When last I reported on Lake Houston dredging, the focus of operations had shifted from the East Fork to Rogers Gully. However, the dredgers were still stationed hundreds of feet offshore. According to State Representative Dan Huberty, shallow water forced them to dredge their way into the Gully. (See below.)
Compare Photos Taken Today
Now, 2.5 months later, the dredgers have reached the Rogers Gully mouth bar and have completed dredging most of it.
Aerial photos taken this afternoon show that all but a small portion has already been removed. The operation could be completed in the next week or two, weather permitting.
Pontoons ferry the spoils to a converted marina across the lake now used as a temporary placement area. From there, trucks take the spoils to a fill-dirt company on FM1960 near SH99 east.
Before Dredging Began
To appreciate the progress, compare the photo below taken two years ago.
It’s not clear yet where the dredges will go next. They’re on a mission, with money that Huberty helped obtain from the legislature, to open up more ditches and streams that empty into Lake Houston. Blockages like the one at Rogers Gully can reduce the conveyance of streams. They create sediment dams that back water up. And that contributes to flooding homes and businesses behind them.
Rider to SB 1 Added During Last Conference Committee
The rider actually stipulates the money will go to the Texas Water Development Board but earmarks it. The text says in part, “Water Development Board shall allocate $50,000,000 for the state fiscal biennium beginning September 1, 2021, for the purpose of providing financial assistance for removing accumulated siltation and sediment deposits throughout the San Jacinto River and Lake Houston.”
The bill became effective on 9/1 after a final conference committee, vote and the Governor’s signature. Huberty credits Chairman of the House Appropriations Committee, Greg Bonnen, Representative Armando Walle, also on the House Appropriations Committee. Huberty said, Bonnen helped it go in and Walle made sure it stayed in.
Huberty said the money will be used to keep dredging continuously as long as it lasts. The City will actually be doing the dredging (see photos below). Huberty also credits Mayor Sylvester Turner and Mayor Pro Tem Dave Martin for working to make the appropriation happen.
Where Money Will Be Used
In addition to East Fork dredging, Huberty sees the money being used to clear accumulated siltation from the mouths of inlets around the lake, such as those in Huffman, Atascocita and Walden.
Update on Status of East Fork Dredging
Shortly before sundown today, I put a drone up from Kingwood over the East Fork and captured the images below.
The shot above shows you just how big this task will be. I first photographed these dredges in the East Fork on October 12. So it’s taken them roughly five weeks to excavate the sandbar between the two pontoons.
Below, you can see what the same area looked like almost a year before dredging started. The photo gives you some idea of the immensity of the task. The sand bars you see grew 4000 feet in length during Harvey and Imelda.
Josh Alberson who boats this area regularly with a shallow draft jet boat found that the depth of the river through his reach had been reduced from 17 feet before Harvey to about 3 feet after Imelda. That’s a major loss of conveyance that backed water up and contributed to flooding on both sides of the river.
Smaller tributaries exhibit similar problems, for instance Rogers Gully.
Thank You Dan and God Speed
Everyone in the Lake Houston Area owes Dan Huberty a huge “thank you” for this one. Huberty, who has served in the House for 10 years, has announced his intention not to run again. Throughout his tenure, Huberty helped reform state education funding. He also passed regulation that forced sand mines to register with the TCEQ during his freshman year in 2011. God speed on the next leg of your journey, Dan.

State Representative Dan Huberty has introduced House Bill 2525. It would create a Lake Houston Dredging and Maintenance District within Harris County. That would include the headwaters of the lake on the East and West Forks of the San Jacinto. The District would have the power to remove sediment and debris on an ongoing basis in perpetuity.
The District would NOT have the power to levy taxes or condemn land, but it COULD enter into interlocal agreements with political subdivisions and corporate entities to help cover expenses and repayment of bonds. The Mayor of Houston and the Harris County Judge would appoint a board to govern the District.
House Bill 2525 would take effect immediately if receives a two-thirds vote of both houses. Otherwise, it would take effect on September 1, 2021 if signed into law by the governor.
Brandon Creighton has filed an identical companion bill in the Senate, SB 1892. Neither bill has passed through committees yet.
Public Hearing Scheduled for Tomorrow Morning
The House Natural Resources Committee will hold public hearings on HB 2525 Tuesday morning, 4/13/2021. You can support the bill three ways at this point:
The House convenes at 10 AM and the committee will reconvene upon adjournment. “If we do not get to the bill in those first two hours,” said Casey Christman, Huberty’s assistant, “it may be last afternoon before it gets heard. It could end up being a very lengthy day.”
Key Points to Make
All things considered, I chose to register my support via the house website. It could not have been easier and only took a couple minutes. The site is extremely well organized. The key points I made included:
Maintenance on the lake has been deferred for decades.
The removal of accumulated sediment will reduce flooding and increase lake capacity.
This will support the economic vitality of the region.
Please support House Bill 2525. To learn more about sediment and debris buildups around the lake, see these posts:

In the 2021 Legislation session, State Rep. Dan Huberty introduced HB2525, a bill to create a Dredging and Maintenance District for Lake Houston. Senator Brandon Creighton introduced an identical companion bill in the senate, SB1892. It deserves the support of everyone in the Houston region who depends on the lake for water as well as those whose homes and businesses flooded during Harvey.
In the three and a half years since Harvey, according to boaters and residents, we have not yet been able to restore the area between Kings Point and Atascocita Point to its pre-storm depth. We haven’t even removed all of the mouth bar.
We need to figure how much sediment comes downriver every year and remove at least that much with a maintenance dredging program to:
Stop or reduce the loss of reservoir capacity
Reduce the risk of flooding
Show good faith to FEMA, eliminate contentious arguments with regular river bottom surveys, and demonstrate how much build-up resulted from a particular disaster.
We also need to be able to quickly accelerate the program after major storms such as Harvey and Imelda.
How You Can Help
I urge you to support HB2525. Write as many local leaders on the City, County and State levels as possible. Pay particular attention to the House Natural Resources Committee where the bill is pending hearings right now. State Senator Brandon Creighton has filed an identical companion bill, SB1892, which has been referred to the Local Government Committee.

State Representative Dan Huberty filed HB2525 on March 1, 2021 to create a dredging district to perform ongoing maintenance dredging on Lake Houston. However, the boundaries of the District will be the boundaries of Harris County. As of March 2, Huberty’s bill does not yet have a senate sponsor, nor has it yet been referred to a committee.
Need for Maintenance Dredging Recognized Decades Ago
Back in 2000, the Brown & Root Report, which came out of the 1994 flood, recommending maintenance dredging to prevent the kind of sediment buildups that contributed to Harvey flooding. But nothing was ever done until after thousands of homes and businesses flooded during Harvey.
Meanwhile, more sediment comes downstream with each flood. And that 2019 money won’t last forever. So ever since the last legislative session, Huberty has sought a permanent solution.
What HB2525 Does and Doesn’t Do
Here are the details of HB2525. The bill will:
Create a special purpose dredging and maintenance district whose operations are limited to Harris County and Lake Houston (including East Fork, West Fork and mouths of tributaries such as Rogers Gully, Luce Bayou and Ben’s Branch.
Maintenance will consist of the removal of floating debris, such as trees that clogged the waterways after Harvey.
The district will be governed by a board of seven.
Harris County Commissioners will appoint three directors.
Houston City Council will appoint three.
The County Judge and Mayor will jointly name the board’s presiding officer.
The District may:
Form interlocal agreements with other political subdivisions and corporate entities or persons to perform the work.
Seek grants of money, equipment or other resources to assist in its operations.
It may not:
Finance, develop or maintain a recreational facility.
Exercise eminent domain.
Perform the same functions as an overlapping conservation or reclamation district.
In addition to raising money from grants, HB2525 gives the District power to issue revenue bonds, but it may NOT levy a tax.
In formulating this bill, financing District operations received considerable discussion. Casey Christman, Huberty’s assistant, said, “We will have a committee substitute on this bill that makes several changes. But this bill would let the Lake Houston Dredging and Maintenance District (LHDMD) create individual interlocal agreements with each entity that purchases water, which at last count was about 68 organizations.”
“The terms of each agreement may differ (i.e. commercial vs. residential) but will outline how and where the fees are assessed. Also, LHDMD would be eligible to apply for grants or funds from other governmental entities, like FEMA or TWDB. Lastly, the new language will permit LHDMD to sell any materials collected. All options could help pay down bonds,” said Christman.
Thanks to Representative Dan Huberty for his persistence and leadership on this issue.

Of course, even when the above water portion of the Mouth Bar is removed, that will still leave a huge portion below the surface. However, all progress is welcome.
At the start of October, the above-water (sub-aerial) extent of the mouth bar was down to the width of one excavator. Two excavators are now working toward the middle from each end. See below.
Like an Iceberg, Most of a Sand Bar Exists Below Water
That’s significant progress given what we started with. But much sand remains below the surface.
Tim Garfield and RD Kissling, two leading geologists now retired from one of the world’s largest oil companies, mapped the depth of the river using sonar and depth poles. They found an underwater plateau exists in this region of the river. See chart below.
Plans for Next Phase Still Not Revealed
FEMA has approved dredging another million cubic yards. And Dan Huberty’s amendment to SB500 in the last legislature dedicated $30 million for dredging the West Fork Mouth Bar. The City is drawing up plans, but they have not been announced yet. The last time I talked to Stephen Costello about this, he said the City was leaning toward dredging a channel somewhere south of the mouth bar. But many details remained to be worked out, such as:
Method of dredging (hydraulic vs. mechanical)
Finding qualified contractors
Determining a suitable placement area, etc.
More news when its available.

Aerial photos of the West Fork Mouth Bar show that the above-water portion on this once-massive sand bar is now down to the width of one excavator for most of its length. A mouth bar is a sand bar where the mouth of a river or stream meets a standing body of water, such as Lake Houston. As water slows when it reaches the standing water, sediment carried downstream drops out of suspension.
The Before Shot
The first photo below shows the West Fork Mouth Bar immediately after Harvey and before any remediation work took place.
At that point in time, the mouth bar extended five feet above water in places. It was 3/4 of a mile wide and a half mile from the northernmost part to the small island in the channel south of the bar. But the part you can’t see, below water, is even bigger.
This massive blockage backed water up throughout the Humble/Kingwood/Atascocita area, and contributed to the flooding of thousands of homes and businesses.
I took the shot below on Sunday night, 10/4/2020. While the camera position and lens perspective are slightly different, they are close enough to show the progress made in removing the blockage, or at least the portion above water.
Close comparison of these two photos shows several smaller islands beyond the mouth bar that the Army Corps removed a year ago. At the completion of the Emergency West Fork Dredging Program (2018/19), FEMA agreed to dredge 500,000 cubic yards (CY) of sediment in a 600-acre area between the mouth bar and Atascocita Point in the upper right of the photos. After dredging the 500,000 CY, the Corps increased the average depth of that area to 5.5 feet. However, within weeks, Imelda filled much of that back in.
This year, the City of Houston started excavating the above-water portion of the mouth bar. The bar is now down to width of the excavators used for mechanical dredging. To fund this effort, the City used money left over from Hurricane Harvey cleanup.
Biggest Part Remains Below Water
But like icebergs, most of the sediment in sand bars lies below the surface. So even when there’s nothing left for me to photograph from the air, most of the blockage will remain. Two local geologists recently measured several cross sections of the river. The river’s profile looks like this.
River depth upstream near Kings Harbor and downstream near the 1960 Bridge is more than 22 feet. Between those two points (which lie about three miles apart), the deepest part of the channel is only about 6-7 feet. Not far from the main channel, however, the river gets much shallower. It’s one to three feet in most places.
The continued presence of this plateau will slow water down and trap more sediment, undermining the effectiveness of earlier efforts.
More Dredging Slated
Restoring the conveyance of the river after decades of deferred maintenance will require much more dredging after the above-water mouth bar is gone.
Luckily, FEMA has agreed to dredge another million cubic yards, according to Houston Mayor Pro Tem Dave Martin. State Representative Dan Huberty also secured an additional $30 million in funding in the last legislature to continue the effort.
Stephen Costello, the City’s Flood Czar, is currently working on developing a next-phase plan, but has not yet announced it.

In the meantime, other related dredging projects, including East Fork dredging and long-term Lake Houston maintenance dredging are reportedly taking shape. Here’s how pieces of the puzzle fit together. But one piece is still missing – long-term funding to pay for the maintenance dredging.
DRC’s scope of work has two distinct phases:
Phase One will remove accumulated materials near and at the mouth bar on the West Fork of the San Jacinto River.
Phase Two will remove accumulated materials in the East Fork of the San Jacinto River AND other locations in Lake Houston.
During Phase One, 400,000 cubic yards of material will be removed over twelve months. To date, DRC has removed approximately 240,080 cubic yards of material. (See photo above.) That’s 60% in approximately 60% of the allotted time, so that part of the project is on schedule.
Phase Two of the project will consist of:
Hydrographic surveys of the West Fork of the San Jacinto River, the East Fork of the San Jacinto River, and Lake Houston to determine dredge material volumes
City of Houston advertising and awarding a dredging contract to the lowest responsive bidder
Phase Two will run simultaneously with Phase One to expedite dredging.
Dave Martin, Houston Mayor Pro Tem
Mayor Pro Tem Martin did not provide an update on where Phase Two currently stands. But residents have reported seeing survey boats on Lake Houston, and the East and West Forks of the San Jacinto.
Long-Term Dredging Plan in Development
Additionally, during Phase Two, City of Houston and its partners will develop a long-term dredging plan for Lake Houston. City of Houston or the Coastal Water Authority will execute the plan.
The intention: to fund dredging operations in perpetuity.
This phased approach will obligate the full grant funding before the 87th legislative session in 2021. This grant funding was made possible thanks to State Representative Dan Huberty (District 127) through the passage of Senate Bill 500.
Mayor Pro Tem Martin credits Huberty for his dedication to the long-term maintenance dredging activities on Lake Houston. “Representative Huberty has been a champion for his residents and a great ally in seeing these additional dredging efforts come to fruition,” said Martin.
$40 Million Project
The total project is valued at $40 million (except for the perpetuity part). Funding for the immediate dredging projects comes through a combination of:
City of Houston Harvey Disaster dollars provided by Governor Greg Abbott
Grant dollars from the Texas Water Development Board (TWDB)
Harris County Flood Control District (HCFCD) Bond Program.
Long Term Funding – Still A Missing Piece of Puzzle
Lake Houston, a City of Houston asset, is losing capacity. Everyone has recognized that fact for decades. But as silt filled the rivers, inlets and lake, maintenance was deferred, reportedly for budgetary reasons. In 2017, during Harvey, the problem became so big that no one could ignore it anymore. Flooding was the immediate problem. But loss of water capacity is an even bigger, longer-term problem.
It’s one thing to have a long-term maintenance dredging plan and another to put it into action. But where will the money come from?
A tax on sand mines? Won’t work. Most aren’t in the City. Or even in Harris County.
Some have suggested creating a taxing district for lakefront homeowners. That won’t work either. Not enough of them. And it would create a stampede for the Oklahoma border. Moreover, it hardly seems fair; the lake is part of a City system that provides water to two million people and generates revenue.
The logical solution seems to be increasing the cost of water. Adding just a fraction of a penny per 1000 gallons should do it. Dredging isn’t just about reducing flooding. Or preserving views for lakefront homeowners. It helps preserve the lake’s capacity. And that benefits everyone.

Correction on 7/4/2020: The article below was based on a City of Houston District E newsletter. It inferred that the City “applied for” five grants (in bullet points below). Other entities, such as the SJRA, applied for those. Mayor Pro Tem Dave Martin personally supports them.
The City of Houston has submitted several applications to the Texas Water Development Board (TWDB) for Flood Infrastructure Fund dollars. Among the projects was one for Taylor Gully Flood Damage Reduction. It consists of evaluating flood reduction alternatives plus design, permitting, and construction of a detention basin located on a 278 acre site to the north of the Elm Grove subdivision.
Woodridge Project One of Six Apps
Other applications include:
San Jacinto River Sand Trap Development
Spring Creek Watershed Flood Control Dams Conceptual Engineering
Upper San Jacinto River Basin Regional Sedimentation Study
Lake Conroe-Lake Houston Joint Reservoir Operations Study
Harris County MUD #153 Siltation Reduction
“All of these projects submitted for funding promote regional resiliency and future sustainability in an effort to protect life and property from future flooding,” said Mayor Pro Tem and District E City Council Member Dave Martin. “The ability to submit these projects to the TWDB for funding would not be possible without State Senator Brandon Creighton’s writing of Senate Bill 7. We continue to applaud the Senator for his forward thinking and hope to receive funding for these projects. State Representative Dan Huberty has also been a vocal proponent for resiliency within our area and just beyond the City boundary. We are thankful to have him as a local engaged leader.”
Neither Martin, nor his office, provided additional details on any of the grant applications.
However, from the wording of the release, it sounds as though state leaders are fully aligned and engaged to support the projects.
Woodridge Village Project Has Long History
The grants, if approved, could help reduce flooding throughout the Lake Houston Area.
Both the City and County have been silent on any deal since then. The County refused a Freedom of Information Act request to release the text of the motion, which was approved in a public meeting. They even protested release of the information to the State Attorney General.
Putting Application in Historical Context
The following is speculation, but speculation based on the historical context. It appears that when County Commissioners voted to demand that the City come up with half the the purchase AND construction costs, the City found it hard. The grant application, if successful, is a way for the City to help the people of Elm Grove, who flooded twice last year after Perry Homes cleared 268 acres of adjacent land.
At the time of the floods, less than 25% of the planned detention pond capacity was in place. Perry has since developed additional detention ponds that provide the other 75%.
A joint reservoir operations study seems necessary. Currently, FEMA is funding a preliminary engineering study to add additional gates to the Lake Houston Spillway. If FEMA also approved the money for construction of the gates, they will be a game changer.
The Spring Creek Watershed flood control dams would provide additional upstream detention. Community leaders identified that as a high priority after Harvey. They would reduce the amount of water coming downstream during a flood.

A “Proposed Agreed Order” dated April 14, 2020, spells out the basis for the alleged violations. Such orders represent a way for both Texas Concrete and the TCEQ to avoid the cost of litigation. The goals of the order: to reach a fair settlement under Texas law and force Texas Concrete to take corrective actions.
Unless Texas Concrete signs the order and pays the fine within 60 days, TCEQ will forward the case to its litigation division. The settlement offer then becomes void.
More Recent Alleged Violations
The enforcement action is in addition to a more recent investigation launched on April 28th of this year. The investigation alleged unauthorized discharge of water and lack of stabilization at the site. A TCEQ letter in response to an inquiry by State Representative Dan Huberty indicated that the investigator could not gain access to the site because no one was there. However, the investigator made limited visual observations from the property boundary. No processing activity was noted. There is no signage. And portions of the Site appear overgrown with vegetation.
The letter also indicates that TCEQ has tried to contact the site’s owner to gain access to the property for a proper investigation.
However, all communication efforts since April 28 have been unsuccessful.
Case Demonstrates Need for Performance Bonds for Reclamation
Calls to Texas Concrete’s headquarters in Houston by ReduceFlooding.com received a similar response. The person answering the company phone claimed they had no plant in Plum Grove. The person also said that she had never heard of Mr. Somaiah Kurre, the person listed as President of Texas Concrete Sand and Gravel, Inc. on the company’s permit. The phone of the plant’s manager had been disconnected.
The company’s web site indicates the Plum Grove Plant is still in operation, even though equipment on the site has not moved since December 1, 2019.
Ironically, Pit & Quarry magazine, and industry trade publication, featured the Texas Concrete Plum Grove Plant as a model for how to adapt to change. The article was dated January 16th of this year.
In the meantime, the plant represents a safety hazard to area children. The gate presents no real barrier to someone intent on trespassing. Pits on such mines can be 90 feet deep according to industry sources. And perimeter roads often collapse.
Such problems underscore the difficulty of getting operators to reclaim a mine when it becomes unprofitable. That’s why Texas should establish performance bonds that guarantee reclamation before the State grants a permit to begin mining.
“We will make sure they fix this,” said State Rep. Huberty. Huberty’s staff is already drafting more sand mining legislation for the session next year.
