1/15/25 – The City of Houston’s latest West Fork Dredging Program appears to be off to a fast start. Dredging began about a month ago and has already filled up approximately 10 percent of the placement area. The program was originally estimated to last two years.
Shortly after sunrise yesterday, Callan Marine’s General Pershing Dredge lifted its bit out of the water temporarily as the dredge was repositioned. Note the FM1960 bridge downstream in the upper right.
Pictures Taken 1/14/25
Yesterday morning, the Callan dredge was anchored off Atascocita Point. Just three weeks ago, it began across the river in Kingwood. The pictures below tell the story.
Looking N.Atascocita Point on left and Kingwood on far side of river. Can you spot the Kings Point water tower?
Callan will pump slurry to the placement area through that winding 18″ pipe in the photo above. It goes approximately four miles to an area near the Luce Bayou Interbasin Transfer Canal. See pictures below.
The Amazing Maze
There, Callan separates the water from sand and silt with an ingenious maze. The twists and turns in the maze slow the water down, so sediment drops out of suspension.
Water comes in at the upper right and exits near the same point. Note how the sediment is higher on the wall near the entry, then tapers off. To visually estimate percentage of completion, compare levels on both sides of the diagonal berm in right foreground.
The 35-acre pond currently in use is surrounded by berms approximately 6-8 feet tall that contain the slurry. Callan has room at this same site to build another pond of approximately the same size. The two together will total 70 acres.
Cleared but unfinished areain foregroundwill contain a second pond. Luce Interbasin Transfer Canal on right.Notice how bulldozers have built small temporary walls that channel the slurry away from areas where fill has already reached the full height of the berms.When filled, this area will be high and hard enough to build new homes on.
Bulldozers spread the sediment out in layers that allow excess water to drain out or evaporate. One dredging expert told me that when dry, the sediment will be hard enough to support foundations and homes.
Small, low temporary berms within the placement area concentrate the slurry where workers want it to go.
Water that Doesn’t Evaporate Returns to the Lake
The pictures below track the movement of water within the placement area.
Slurry shoots in from the dredge almost 4 miles away.Then bulldozers spread out and compact the dirt.Water that doesn’t evaporate eventually makes its way through the maze back to the two pipes (center at bottom)Boards in front of the exit pipes control the level of water in the pond and the rate of outflow.After dirt is separated from the water, any remaining water that doesn’t evaporate re-enters Lake Houston (upper left).
Comparison with December
To see how much progress Callan has made, compare the pictures above with the one below taken, just three weeks ago.
Progress as of 12/21/24.
Beneficial Use
I wonder if that return channel will become a ready-made detention basin when the landowner develops the site. This is an ingenious example of “beneficial use” – turning a problem into a solution.
Up the Down Escalator
Nevertheless, there is a cost associated with dredging. Funding for the program comes from FEMA via U.S. Congressman Dan Crenshaw. The City will use money left over from previous West Fork Mouth Bar dredging. Crenshaw secured $125 million in federal funding to cover dredging, including phases already completed.
Some of the sediment shown above comes from natural erosion. Some also comes from upstream sand mining.
With 20 square miles of sand mines in a 20-mile reach of the West Fork between I-45 and US59, the average width of exposed sediment during floods is one mile.
Sometimes I compare flooding issues to trying to walk up a down escalator.
In this case, we’ve failed to establish an effective regulatory regime based on a comprehensive set of best management practices for sand mines. And the public is paying the price in terms of increased flood risk and mitigation costs.
If you haven’t already written the TCEQ to register your concerns about their proposed (but inadequate) best management practices for sand mining, please do so. The public comment period ends on January 24. This post contains more about the problems with the TCEQ’s proposed BMPs. Texans for Responsible Aggregate Mining has even bigger concerns which I posted about yesterday.
Please mail your concerns to Jess Robinson, MC 175, Office of Legal Services, Texas Commission on Environmental Quality, P.O. Box 13087, Austin, Texas 78711-3087. Or you may submit them electronically. Comments must be received by 11:59 p.m. on January 24, 2025, and should reference “APO BMP List Proposal.”
So far, only a handful of people have registered public comments. So please help.

1/14/25 – Texans for Responsible Aggregate Mining (TRAM) has issued a position paper that pans a new set of Best Management Practices (BMPs) for mining that the Texas Commission on Environmental Quality (TCEQ) has proposed. TRAM calls TCEQ’s BMPs “sparse,” “vague,” and “self-evident.”
TRAM asks everyone concerned about flooding and other issues related to aggregate mining to write the TCEQ before the close of public comments on the new BMPs. The deadline is January 24, 2025.
TRAM has also proposed a more comprehensive list of alternative BMPs that it believes will be more effective at minimizing disturbances created by mining.
San Jacinto West Fork mine complex inundated by floodwaters illustrates need for better BMPs
TCEQ BMPs Fail to Address Legislature’s Requirements
Senate Bill 1 in the 2021 Legislative Session required TCEQ “to adopt and make accessible on the commission’s internet website best management practices for aggregate production operations regarding nuisance issues relating to dust, noise, and light…” But the BMPs ignore noise and light.
SB 1397 and House Bill (HB) 1505 in the 2023 Legislative Session then required TCEQ to adopt BMPs related to dust, water use, and water storage. But the proposed BMPs ignore water use.
TCEQ also ignored Texans for Responsible Aggregate Mining’s (TRAM’s) technical team of credentialed professionals. TRAM created a vetted list of BMPs and presented it to the TCEQ for consideration. Instead of drawing from that resource…
“TCEQ spent three years (September 2021 to December 2024) to produce BMPs so sparse, vague, and self-evident, as to be completely irrelevant and useless.”
TRAM
Description of TRAM Concerns
According to TRAM, TCEQ’s draft BMPs weaken TCEQ’s effort to protect public health and natural resources by “pretending to establish new guidelines while actually saying nothing. It is a disservice to taxpayers and to the environment.”
Sparse
In regard to sparse, TRAM says, “The proposed BMP list fails to address many of the real issues associated with APOs, including issues they were directly charged with addressing.”
“While they addressed dust and water storage (albeit inadequately) the TCEQ completely overlooked the “water use” portion of their 2023 charge.” And they still haven’t addressed noise and light pollution from 2021.
“TCEQ has simply failed to comply with their mandates,” says TRAM.
Vague
TRAM also feels that the TCEQ recommendations are “too vague to be useful.” For instance, “Ensure vehicles are driven at reasonable speeds to reduce dust disturbance.” TRAM suggests posting speed limits of 10 or 15 mph for unpaved haul roads. The group believes that the value of a BMP list is in detailing what a “reasonable speed” ought to be.
TRAM gave another example of vagueness. TCEQ proposed “Use fuel-efficient and appropriately-sized equipment to reduce emissions, operation time, and the overall amount of dust you produce.” TRAM questioned what “appropriately sized” meant.
“How is anyone to assess when a BMP is being implemented,” TRAM asked, “if they are described in completely subjective terms like ‘reasonable’ and ‘appropriate’?”
Self-Evident
TRAM also cited TCEQ recommendations that were self-evident. For instance, “Be sure your stockpiles are only as high as your permit allows,” or “The further dust-producing operations are from the site boundaries, the less likely they will be to create a nuisance for any neighbors.”
“Who benefits from these self-evident recommendations and simple reminders to follow the permit requirements?” asked TRAM.
“Completely Inadequate”
TRAM summed up its concerns in two words. “This completely inadequate draft BMP list, three years in the making, only weakens TCEQ’s effort to protect public health and natural resources by pretending to establish new guidelines while actually saying nothing. It is a disservice to taxpayers and to the environment.”
Whatever BMPs TCEQ ultimately settles on, they will neither be required nor incentivized. Still, TRAM believes it is paramount that the list be thorough and well vetted. That’s because, “It will serve to educate the public about what quarry operators could be doing to be good neighbors.”
Send Feedback to TCEQ Now
TRAM and its member organizations ask that you submit public comments to TCEQ at the address or website provided below by the January 24th deadline.
Mail comments to Jess Robinson, MC 175, Office of Legal Services, Texas Commission on Environmental Quality, P.O. Box 13087, Austin, Texas 78711-3087. Or you may submit them electronically. Comments must be received by 11:59 p.m. on January 24, 2025, and should reference “APO BMP List Proposal.”
TRAM suggests mentioning the inadequacies above. The group also suggests including BMPs from TRAM’s list that are most important to you. And insisting TCEQ addresses unaddressed issues required by the Texas Legislature: water use, noise, and light pollution.
More Complete List and Thorough Descriptions Needed
Further, they suggest addressing more issues more completely. For instance, some of the many BMPs that should be included are:
Dust Control: Roads and parking areas for vehicles that will leave the site should be paved.
Light Pollution: Direct light properly and use perimeter barriers to eliminate sky glow, light trespass, and glare.
Mine Management and Truck Safety: Clear roads for school buses by not loading trucks for 30 minutes before and after school bells.
Noise: APOs should monitor the noise exposure at their property line, keeping the noise level below 65 dB if within 880 yards of a residential area, school, or house of worship, and 70 dB if not. Set noise criteria using MSHA on-site guidance and limits from nearby municipalities.
Blasting: Blasting should be monitored with seismographs, located on the perimeter (corners) of the APO property (and in some instances, adjacent or near-by properties in multiple directions).
Water quality: Vegetation is an inexpensive and effective way to protect soil from erosion and filter contaminants, protecting water quality in nearby streams and aquifers. It also protects air quality by holding dust down and filtering the air. Vegetative controls should consist of native plants appropriate for the Texas ecoregion where the site is located and must not include any noxious or invasive species.
Water use: Maximize re-use of process wastewater. Manage fine tailings to reduce volume in settling ponds. Use a tailings thickener system and/or flocculant, as many APOs do. These can provide additional recycled water, reduce water loss and also reduce land use.
Riparian health and safety: In riparian areas, reduce the risk of catastrophic “pit capture” (when a river breaks through the riverbank or constructed levy and runs through the mine pit, as has happened countless times in Texas, due to poor mining practices) by:
Maintaining an undisturbed setback of 50-200 feet from the water’s edge. Create a buffer between mining activities and the waterway.
Leaving vegetation in the buffer.
Minimizing use of heavy equipment in buffers to protect vegetation and reduce soil compaction.
ReduceFlooding.Com Suggestion
ReduceFlooding.com agrees with all of TRAM’s recommendations, but given recent erosion, I would suggest that the minimum safe distance from rivers such as the East and West Forks of the San Jacinto, be 200 feet. Fifty feet can be wiped out in one flood.

1/13/25 – The Texas Commission on Environmental Quality has proposed new Best Management Practices (BMPs) for mining in response to a mandate from the 2023 session of the Texas Legislature. However, in my opinion, the recommended BMPs will do little to nothing to help control sediment pollution from mines in the Lake Houston Area.
The BMPs feel like little more than a half-hearted attempt on the part of a reluctant regulator to create the illusion of environmental protection.
You can find the proposed BMPs at this page on the TCEQ website. You may submit comments on them electronically. To be considered, TCEQ must receive your input by 11:59 p.m. on January 24, 2025. Your email should reference “APO BMP List Proposal.”
Please let the TCEQ know what you think even if you disagree with me.
Notable Omissions
The TCEQ’s recommended BMPs do not really address the biggest mining issues we have in the upper San Jacinto watershed.
I urge you to urge TCEQ to develop BMPs that address:
Discharge of sediment-laden water
Pit capture (when a river starts flowing through a mine)
Periodic flooding.
The proposed BMPs do not cover these issues at all.
The final report of a TCEQ investigation into a West Fork pit capture last year didn’t even mention the phrase. Do they not consider it a problem? I sure wish the TCEQ could enlighten us on this issue. I documented seven instances of pit capture in the Lake Houston watershed last year alone. There may have been more; many mines are in remote, difficult-to-access locations.
Sediment Pollution Reduces Water Quality, Increases Flood Risk
All three of the bullet points above add up to a big problem called “sediment pollution.” Dredging costs for the City of Houston and Army Corps approached $200 million dollars as of October 2023. Better BMPs would likely have reduced or delayed that expenditure of public funds.
At an October 2023 town hall meeting in Kingwood, Mayor Pro Tem Dave Martin presented this summary showing dredging costs totaling $186 million.
But those costs paled in comparison to the damages to 13,000 homes and businesses that flooded in the Lake Houston Area behind giant sand bars that formed sediment dams at the mouths of the East and West Forks of the San Jacinto.
Nor do the costs reflect extra water filtration at the City’s Northeast Water Purification plant.
To be fair, nature causes some erosion. The question is whether local mining practices accelerate it.
Photos of Sediment Pollution Related to Discharges, Pit Capture and Flooding
See the pictures below. I will submit these as part of my comments on the draft BMPs. Feel free to submit them as part of yours, too.

Twenty square miles of mines are upstream on the right in a 20-mile reach of the river.San Jacinto East Fork capturing a mine in Plum Grove.Effluent from the Hallett Mine settling pond (white in upper right) on San Jacinto West Fork escaping into adjacent property owned by others.Close up of same effluent from same pondDike of abandoned Williams Brothers Mine (upper right) eroded by the San Jacinto West Fork (lower left) about to give way……was taken out by flooding from Hurricane Beryl shortly after I took the photo above this one.
Hallett sold the San Jacinto West Fork sand pit below to a real estate developer. Within months, the river captured the pit.
West Fork flows into the pit at the north end……and flows out at the south end.The pit in question is to the right of the S-turn in the river (middle). Here you can see both the entry (lower right) and exit (upper right) breaches in the dikes.
River Speed During Floods High Enough to Stir Up and Carry Even Largest Particles of Sand
Now, let’s discuss the speed of floodwaters and whether it’s sufficient to entrain sand in pits and carry it downstream.
Flood inundated both sides of the West Fork during May 2024.My drone measured logs floating through the captured pit at 5 MPH, more than fast enough to scoop up and carry off the largest grains of sand and other sediment.See below.Industry-standard graph shows the speed necessary to erode, transport and deposit sand/sediment of different particle sizes. Blue line indicates measured speed of water. Red indicates range of typical sand sizes.Another West Fork pit capture at the Hallett Mine after floodwaters receded. Notice how natural channel of the river has been virtually cut off.Effluent from the Hallett Mine (upstream in upper right) polluting the West Fork at the Northpark/Oakhurst Ditch (middle foreground). Water flows right to left.Reverse angle shows proximity of pollution to homes.Same ditch blocked by sand increases flood risk for those homeowners.Farther downstream, the Kingwood Diversion Ditch (top middle) also became blocked by sediment. A Harris County Flood Control District study found that the Diversion Ditch was one of the two most dangerous flooding problems in Kingwood.Broken dike at the Triple PG sand mine in Porter. Industrial waste water is flowing out of the mine into White Oak Creek which joins Caney Creek and the San Jacinto East Fork before flowing into Lake Houston.
Horrifying! Aren’t they? The truly horrifying part is that I have thousands of similar shots. These are not isolated instances.
This is THE biggest environmental problem in the Lake Houston Area. We have industrial waste polluting the drinking water supply for 2 million people and the TCEQ BMPs don’t even address the problem.
Don’t forget to reference “APO BMP List Proposal” when you submit the web form. Greater setbacks of mines from rivers could solve all the problems discussed above.

New West Fork Dredging Program Off to Fast Start
1/15/25 – The City of Houston’s latest West Fork Dredging Program appears to be off to a fast start. Dredging began about a month ago and has already filled up approximately 10 percent of the placement area. The program was originally estimated to last two years.
Before it’s all over, Callan Marine, the contractor, will dredge 876,672 cubic yards of West Fork sediment from 181 acres near the mouth of the West Fork in Lake Houston.
Pictures Taken 1/14/25
Yesterday morning, the Callan dredge was anchored off Atascocita Point. Just three weeks ago, it began across the river in Kingwood. The pictures below tell the story.
Callan will pump slurry to the placement area through that winding 18″ pipe in the photo above. It goes approximately four miles to an area near the Luce Bayou Interbasin Transfer Canal. See pictures below.
