Sand Is Choking Lake LBJ, But a Battle Looms Over Its Removal

This article originally appeared in the September 2018 issue with the headline “A Gritty Debate.”

In early 2017, homeowners in Sandy Harbor, a waterfront community in the Highland Lakes chain where Lake Lyndon B. Johnson meets the mouth of Sandy Creek, called Kevin Collier about a problem: sand. There was so much of it that it was preventing some of them from getting their boats in the water. Could he help?

Collier co-owns Collier Materials, a Marble Falls–based company that collects and sells sand, soil, and rock, generally for construction. His most notable project at the time was dredging the reservoirs in nearby Llano, at no cost to the city. Using excavators, Collier Materials pulled sand from the reservoirs to expand their holding capacity, which the town badly needed. The company then refined the sand at a nearby plant and sold it for construction materials.

Over the years, Sandy Harbor had lost much of its lakeside access because of sand that had risen almost to the height of its docks. Now the homeowners wanted to know if Collier could dredge there as well. But he said no for two reasons: Sandy Harbor didn’t have a place to put the sand after he removed it, he said. And, once dredged, the sand needed to be processed in order to be used for anything. To do that economically, Sandy Harbor would need a small industrial facility nearby, which it did not have.

But the volume of this type of sand piqued Collier’s interest; it sells for about $8 to $10 a ton and could be worth a lot in sufficient quantity. So he hatched a plan to clear the waterway—and, in the process, set off a firestorm in Llano County, pitting ranch owners against lake house owners, growth advocates against preservationists, and the needs of industry against the old ways of landowning in rural Texas.

Sandy Creek rises in the northern part of Gillespie County, about a third of the way from Fredericksburg to Llano as the crow flies. It then runs north and east, through Enchanted Rock State Natural Area, constantly eroding the granite and other rock it encounters. Long ago that sand would empty into the Colorado River and be flushed out to the Gulf of Mexico and then to God knows where.

That is, until the Wirtz Dam was completed in 1951, creating Lake Granite Shoals, which was later renamed for our thirty-sixth president. After that, the sand began to accumulate in the 21-mile-long lake’s slow-moving water, shrinking the lake by about one hundred acre-feet a year, according to the Texas Water Development Board. (That’s one hundred acres at a depth of one foot.) As a result, some shallow areas of the lake, particularly those near the mouth of Sandy Creek, need regular dredging, which the Lower Colorado River Authority periodically enables by releasing water from Wirtz Dam, lowering the lake.

Collier wanted to find a way to capture and sell this sand—as much as 1,700 tons a day. To do that, he needed to find someplace upstream to build his operation.

Collier wanted to find a way to capture and sell this sand—as much as 1,700 tons a day. To do that, he needed to find someplace upstream to build his operation, a place with access to the creek, where the sand was flowing; access to state highway 71; and enough acreage to house a refining plant. “The only place that fit that description was Mr. Nash’s spot,” Collier says, referring to Steve Nash, the head of Nash Builders, a construction firm based in Horseshoe Bay, about five miles away. Nash, who moved to the region decades ago, owns land with creek access, a ranch that he and his wife had planned to retire to, before Steve was bitten by a rattlesnake and his wife decided she’d rather live in nearby Marble Falls.

Nash stood to benefit from the plan in two ways. His company builds homes and apartments, part of the area’s recent development boom, and sand is one raw material at the heart of that construction. “We’ve poured over one thousand yards of concrete in the last ten days,” Nash says. “I shudder to think what it would cost if that sand had to be trucked in any further than what it is now.”

By allowing Collier to build a plant on his land, Nash could make money on the sale of sand and cut down on the cost of concrete, which contains sand. The by-products of the mining, too, could go to development: The silt from the refining process, he says, might be used under parking lots. River rock would go to landscaping, and the sand would also make gunite, a cement mixture used to build swimming pools. On his ranch, the detritus of the Hill Country would be shaped into materials to be used in nearby homes and businesses, all the while generating revenue.

But to get there, Collier and Nash will have to secure six permits from five state and local agencies. And the Llano County Commissioners Court, which has no authority because it cannot control land use, bowed to popular sentiment by passing a resolution opposing the plan. Then there are the neighbors, some of whom have already banded together under the name Save Sandy Creek. Once word got out about Collier’s plans, the group made T-shirts and protested at the county commissioners court. They created a website and social media page, objecting to the traffic, noise, and light pollution that a plant would bring to a patchwork of old ranch land. And they’re protesting the demands such a facility would have on their water supply.

Collier and Nash are at the start of the permitting processes and say they hope to build a plant in the most unobtrusive way they can. But they claim that their opponents have been caught up in a kind of hysteria. Nash, for his part, sees the plant’s critics as embodying the same NIMBY-esque reaction he’s always had to stare down as a developer. “Most people are just swept up in the misinformation,” he says, referring to a report in a local news website, the Daily Trib, that indicated the plant would have a deleterious effect on surrounding fish habitats. (Collier says there will be no such effects because the plant will recycle the water it uses and will not release any water into the creek.) “But there’s just a select few who really are no-grow. They oppose anything that has to do with growth.”

Collier says that he and Nash are performing a public service: helping to prevent the buildup of sand in the lake while meeting economic needs in the county. But that is not a popular position. “I just had an employee the other day tell me, ‘Kevin, I’m thinking about taking Collier Materials off of our work shirts. We can’t go into a store. People keep giving us a hard time,’ ” Collier says. “My guys driving their company vehicles, cars just pull up beside them and shoot the finger at them.”

Jennifer and Fermín Ortiz.

Fermín and Jennifer Ortiz own a ranch upstream from Nash’s property, living what appears to be an idyllic life. Fermín is the former chairman of the Llano County Republican Party; Jennifer is in the fifth generation of a ranching family that has owned the land since 1870. We talk on the wraparound porch of an 1872 ranch house, where Jennifer’s uncle was born and died. They live on a nearby hill, in a cabin that once belonged to author J. Frank Dobie, which they bought from the University of Texas and relocated to their land. On the other side of the ranch house is a four-hundred-year-old oak tree whose heavy and sagging limbs are carefully counterbalanced by a complicated system of supports.

The Ortiz family leads the opposition to the sand plant, something made trickier by the fact that Jennifer and Collier are related by marriage. “The Collier family used to play on this creek,” she says. “I grew up around Kevin.” The Ortizes make a number of practical arguments against the plant. But the most important one, Jennifer says, is not likely to be considered during any permitting process. “This land is sacred,” she says. “I think most people who have been here a while feel that way.”

“Everybody out here has been approached” by other business interests about the possibility of mining sand, Fermín says, but they’ve turned those offers down out of an emotional attachment to the land. “People want to argue about property rights, what a man can do with his property,” he says. “I’m a capitalist.” But, he says, alluding to a cardinal rule of hunting, “you don’t shoot towards a neighbor’s fence. There’s a point at which your neighbor’s safety, your neighbor’s livelihood should be in play.”

The impacts are numerous. There’s the truck traffic on a two-lane rural road. Collier has said he expects 40 semis a day, which means up to 80 trips total. (It would take more than 42 trucks a day to remove the volume of sand Collier anticipates.) Then there’s the plant’s noise, which opponents fear would shatter a quiet landscape. The plant is intended to operate from 6 a.m. to 7 p.m. seven days a week, so it will need industrial lights for part of the year. (The original application requested that the plant run 24 hours a day, though Collier says he has since reconsidered.)

Nash contends that the plant would be set in the middle of his acreage and so secluded that it will be barely visible, if at all, to neighbors. (Based on a recent walk through the property, it seems that he is correct about this.)

Then there’s the question of water. Sand crushers like the one Nash and Collier plan to install are thirsty; they say that this plant will draw, at maximum, 30 gallons of water a minute from Sandy Creek. But the operation will need 216,000 gallons a month, which will be recycled. That’s too much for Nash’s neighbors, who rely on the creek’s water for ranch life and are sometimes forced to truck water in, especially during drought years. The climate in the area has changed significantly, Jennifer says: “It used to be cooler and wetter. It is different. And there’s no reason to expect that it won’t continue to be different.” They fear Nash’s operation will deplete the water table while providing no benefit to them.

“We quarry granite out of Marble Falls. The Capitol’s made out of that stone,” Nash says. “Marble Falls was a beautiful dome once, like Enchanted Rock. Now it’s been cut, cut, cut.”

The prospect of a sand plant is part of a greater issue that confronts the Hill Country, Jennifer says: whether these old ranches will survive at all as the area gets hotter, drier, and more saturated with development, as Austin and San Antonio pull more of the region into their orbits. Jennifer fears that the plant will help open the door to industry, that it will be the first of many projects to come to this area to make money.

Here on her land, her sleep is untroubled, she says, except for one recurring nightmare. In the dream, she wakes up, “and right across from my house are houses,” she says, a subdivision of the kind that has recently been creeping this way from Austin. “There’s a lot of families around here that have been here for generations and generations, and that’s a part of Texas I don’t think we want to see go away. I don’t think even the people in the cities want that to go away, because that’s what they like about Texas.”

That’s a real threat, says Cliff Kaplan, who runs the communities program for the Hill Country Alliance, a nonprofit dedicated to the region’s natural systems and rural character. “The aggregate industry appears to have ramped up its operations to meet demand in the Hill Country,” he says. Often these projects, like Collier’s plant, are in unincorporated areas, which means local residents have little say. “The counties have so little ability to do anything that landowners are left without officials who can go to bat for them.”

Compounding that, he says, is accelerating “land fragmentation” in the area. “The large parcels of land that have traditionally been owned by families passing it down from one generation to the next seem to be going away.” They’ve been subdivided into smaller plots that are bought and maintained for a variety of uses. That makes the environment “harder to steward.” There’s a risk, Kaplan says, that the Hill Country “will start to look like anyplace in America.”

Nash is less troubled by growth. In his view, the drive to make use of Sandy Creek is part of the natural order of things. This region, part of a geological oddity called the Llano Uplift, has been blessed with mineral riches, of which sand is just the least valuable, and people have always tried to turn them to productive use. “We quarry granite out of Marble Falls. The Capitol’s made out of that stone,” he says. “Marble Falls was a beautiful dome once, like Enchanted Rock. Now it’s been cut, cut, cut.”

The area’s development boom has been long in the making, he says, and it cannot rightly be halted. “I’ve lived here forty-four years, and this is what I’ve waited for,” he says. “A live oak tree is prettier than a sand screen, there’s no question about it. But I’ve always lived by this: the only constant is change.”

    The article fails completely to mention this all started when a very small group of people petitioned, successfully so, to have all sand removal operations in the river beds stopped years ago. God forbid a drop of oil from their machines hit the water even though as much is done everyday by recreational activity. Ever since, the lake has been filling with sand at an accelerated rate. The middle of the lake is not about 2 feet deep in many places. What once was 15 feet deep river channels is now about 6. Sand removal is necessary so now the issue is how to convince the environmental militants that it can be done without causing the earth to explode. And no wonder nobody comments on Texas Monthly articles, a mountain of spam awaits.

      This article failed to mention the huge amout of Llano County residence that oppose this sand plant and crusher on the beautiful clear waters of Sandy Creek. This is not a handful of people. The City of Sunrise Beach passed a resolution to oppose this Sand Plant/Rock crusher as well as The Llano County Commisioners Court. The people have spoken! No Sand Plant and Rock Crusher on Sandy Creek! This is an attempt to decieve the Sandy Harbor property owners into believing their water front will be dredged and no more sand will pile up at their boat docks at the point the creek meets LBJ. The location of the Nash Builder ranch is miles from the point Sandy Creek flows into LBJ… and the property owners between Nash and LBJ are not signing the Collier Materials contract! Furthermore, Collier Materials has not completed the contract with the City of Llano to dredge the Llano Lake and has left it in a huge mess. Collier wants to move the plant and increase its size and production on Sandy Creek where that sand is alot more profitable for Collier. Don’t be fooled. This is an Evil attempt with much deception, all to profit Collier Materials and Nash Builder corporations. Money is the root of all evil.

        If you will go back several years and look into what the environmental alarmist did, you will see they got laws passed that do not allow equipment to operate in “river beds” which was later interpreted by liberal judges to mean anything near a river. Sand removal on the Llano and Sandy Creek tributaries ceased as a result. The sand in the lake didn’t fall out of the sky, it was a result of stopping the removal of sand further up the rivers. So yes, it is relevant and yes it is contributing to shallow water around the boat docks. Allowing someone to remove sand up river will result in less sand in the lake. It’s really that simple. If someone makes a profit or even an obscene one in the process, so be it. All the sand in the rivers and in LBJ could be removed without bothering a single person or thing but today environmental alarmists are having the day even though not a single prediction they have made has come to fruition. We don’t have beach front property in Denver resulting from ice caps melting and we haven’t lost our ozone layer. I bet the population of Venezuela would gladly accept anyone into their country who will make a profit if they could just buy food and not have to flee the country to keep from starving, all a direct result of people voting against profits.

        • St. Anger

          Do you think maybe the sand pileup is related to blocking a river and calling it a lake?

          • David Nix

            Good thinking. We can remove the dam and we won’t have a sand problem.

        • JAMES CARAS

          “Allowing someone to remove sand up river will result in less sand in the lake. It’s really that simple.”

          No, it’s not that simple and will actually have the opposite effect. Numerous scientific studies in the area of hydrogeology have demonstrated that digging/mining in any river or creek with moving water erodes the banks both upstream and downstream of the sand mine and leading to increased sedimentation overall.

          • David Nix

            Yes, it really is that simple. Quoting some “scientific study” that finds otherwise is idiotic. It is to ignore and deny the evidence before us. The sand accumulation has become exponentially worse in the last 10 years since the sand removal was halted. Ask anyone that knows the lake and it’s depths in each area of the lake. We don’t need a study or to speculate, it has already happened.

          • JAMES CARAS

            I don’t know why you put scientific study in quotes, as if they are not real things that should heavily weigh in on any decision-making. It is not one scientific study, it is the consensus of many I have read and posted about in other forums regarding the sand mine.

            You are conflating two things that have differing consequences.

            Yes, sand removal *from the waters of lake LBJ directly in front of the docks* in Sandy Harbor has helped those neighbors. While I might speculate that that too increases erosion upstream because of what I have read, I understand their plight and would never deny them that right.

            However, dredging in Lake LBJ is very different from mining sand a mile or so upstream of the Sandy Creek/LBJ delta. The evidence that sand mining in creek- and riverbeds leads to increased erosion and sediment migration both upstream and downstream of the mining site, and is the consensus view of many papers I have read on the topic written by many hydrogeologists, all backed by empirical research and observable scientific evidence.

            in my research it has also been noted that where tributary creeks and rivers enter a lake, a delta will form of the more course sediment (sand). And that the encroaching sand will build up and slowly migrate towards the dam. There are three ways to deal with this proposed by scientists who care about protecting the recreation and holding capacity of the lake (and lifetime of the dam that formed it), none of them very good: (1) route sediment-laden flow around the lake via an alternative channel, especially during and right after precipitation events; (2) build smaller dams further up the tributary creek to slow the water and allow sediment to collect behind them; or (3) dredge the sand out of the lake. None are inexpensive solutions, and none are mining the tributary feeding the lake.

            Building smaller dams near the entrance to lake LBJ is probably the only viable option other than simply dredging, but then those smaller dammed reservoirs fill quickly and then have to be dredged to make them useful for longer periods of time. The impact of building any dam is that it significantly reduces sediment travel downstream, since the sediment collects there.

            In terms of the sand mine, digging a hole is not the same thing as putting up a dam. Digging causes erosion upstream as the potential energy difference between the particles upstream and the bottom of the hole is increased, and particles will then move at a faster rate downstream to fill the hole. A dam puts a potential energy barrier that catches sediment that would flow normally, and does not induce erosion and sediment flow upstream of it. This is why I believe that mining is detrimental to sediment flow into the lake, or at best neutral, while a small dam that is dredged regularly to keep it operational is beneficial.

            Again, just to reiterate: dredging only helps Sandy Harbor if you are directly dredging the sand in front of their docks. From what I have read and analyzed, dredging upstream of your docks in Sandy Creek only hastens the rate at which the course sand delta fills and expands.

            I am not an unconcerned party looking to poke at an online article. I am concerned about the course sediment (sand) buildup in the Sandy Creek arm of lake LBJ because I have a dock right on it just downstream of the “party sandbar” (which will only be getting larger) and eventually (years away but still) I will be having to dredge in front of my dock just to get the boat in and out. But what I don’t want to do is encourage dredging upstream on Sandy Creek thinking it will help, when after hours of research I am now convinced that the dredging/mining will only accelerate the problem.

            So I am trying to speak truth, to selfishly protect my own interests as well of those of my “upstream” neighbors. I have no incentive to argue against doing something that would help me.

          • JAMES CARAS

            Couple of other points:

            1) You are right that sedimentation seems to be getting worse:
            “The rate of capacity loss on Lake LBJ (due to sediment accumulation) has nearly tripled during the period from 1995 to 2007 when compared with the period from 1951 to 1995. This increase in sediment accumulation rates may be attributed to increased development within the Lake LBJ watershed.”

            (Volumetric and Sedimentation Survey of Lake Lyndon B. Johnson, May 2007 Survey. Prepared for the LCRA by the Texas Water Development Board, April 2009.

            So if anything the introduction of further development in the form of a sand mine and associated infrastructure right on Sandy Creek will only exacerbate the solution. Furthermore, the Collier family has stated numerous times that he wants increased development (housing, businesses) in the area. This is in addition to the impact of the sand removal.

            2) Sedimentation of lakes does not occur uniformly across a lake bottom. Course sediment (sand) localizes at the delta – causing the problems in Sandy Harbor. The fine sediments flow to the deepest part of the lake, right by the dam, and are the cause of the ever shortening lifespan of a dammed lake for generating hydroelectric power. Almost everywhere else the depth is generally unaffected. This is true for studies done decades ago for Lake Powell and other lakes confronting similar issues, and documented more recently here here for LBJ:

            “The thickest sediment deposits are in the submerged river channel throughout the main lake body, and sediment was not present in the Llano River arm, Colorado River arm, or Sandy Creek arms of Lake LBJ. This sediment distribution suggests incoming sediment quickly travels downstream within Lake LBJ, where it settles to the
            bottom, upstream of Wirtz Dam.”

            (Volumetric and Sedimentation Survey of Lake Lyndon B. Johnson, May 2007 Survey. Prepared for the LCRA by the Texas Water Development Board, April 2009.

            Again, I have done tons of research in this area. I am a trained scientist (admittedly a PhD Biochemist). The info I have provided above is but the tip of the iceberg.


    Note that Collier is not proposing they will dredge the sand from in front of the docks of concerned citizens of the Sandy Creek neighborhood (and they do have a problem.. no doubt).

    Everyone seems to believe that removal of sand in a creek that feeds into lake LBJ will result in lower sedimentation of the lake. But numerous scientific studies in the area of hydrogeology have shown the opposite: that digging in any river or creek with moving water has the opposite effect: eroding banks upstream and downstream of the sand mine and leading to increased sedimentation overall. This will compound the problem for the water-font properties around Sandy creek and also lower the expected lifetime of Lake LBJ in terms of the hydroelectric power obtained from Wirtz Dam as the fine sediments settle against it at the deepest part of the lake.

    The only reasonable way to mitigate course sedimentation buildup in the deltas where a creek enters the lake is to build smaller crude dams (rising above the creekbed, NOT a hole that fills) upstream of the delta to form a barrier by which sand will pile up behind, and then remove that sand periodically. This would give Collier the sand it needs while also being a service to the neighborhood. But again, this is NOT what is proposed.

    The writer failed to mention there are 47 MILES of sand along the banks of Sandy Creek. The vegetation has certainly been reduced after the years of drought we had leading up to current time. Dredging only worsens this effect. All that sand flows downstream each time we have a big storm event. The most recent flooding caused SO much sand to flow down that new islands were formed in the middle of Lake LBJ. People who didn’t have sand before now have thick sand “beaches.”
