In the last legislative session, State Representative Dan Huberty sponsored an amendment to Senate Bill 500. The amendment earmarked a $30 million grant for additional dredging at the confluence of the San Jacinto River and Lake Houston. Last week, Harris County approved the grant application to the Texas Water Development Board. That will actually transfer the money so that it can be put to work.
How $30 Million Grant Would Be Spent
County Engineer John Blount explains how the money would be spent in his cover letter that accompanied the request to Commissioners.
“The approach to completing work under the grant,” says Blount, “would be for the County to receive the grant funds, make the City of Houston a subrecipient to start immediate dredging, and to develop a long-term plan for keeping the region’s raw water supply viable with adequate reservoir capacity. The County would be reimbursed from the grant for administrative and other related expenses incurred.”
County Plays Central Role In Coordinating Effort
Blount concludes, “If authorized, the County will work with the Flood Control District, Budget Office, County Attorney, City of Houston, and the State of Texas, to advance all necessary applications and agreements needed to initiate the dredging activities funded in the 2019 legislative session. Grant awards, if made, will be presented to Commissioners Court for consideration at a future date.”
Commissioners Court approved the motion unanimously in its Tuesday, December 17th meeting. And by Friday, the actual grant application had been sent to the TWDB, according to Matt Zeve, Deputy Executive Director of Harris County Flood Control. The TWDB board should consider the request at its first board meeting in January, tentatively scheduled for the 10th. Huberty expects quick approval because the Legislature earmarked the money specifically for this purpose.
As a result of sediment deposited during Harvey and Imelda, the East Fork Mouth Bar grew southward 4000 feet and now has almost reached the point where Luce Bayou and water from the Trinity River will enter Lake Houston.Photo taken 12/3/2019. Water flows from left to right.
West Fork Also Plays Role in Water Transfer
That’s also why the West Fork must remain clear. It brings water, when needed, from Lake Conroe.

Looking northwest toward the San Jacinto River and the West Lake Houston Parkway Bridge. Note the submerged sand about to break through the water surface around the mouth bar.Photo taken 12/3/2019.Kayaker RD Kissling standing in less-than-knee-deep water 700 yards south of the West Fork Mouth Bar.Photo taken November, 2019.
Like icebergs, sand bars mostly exist below the surface. What you see above water is a small percentage of what exists below water.
These photos illustrate why more dredging is essential. The mouth bars form dams behind the dam that block the free flow of water and decrease reservoir capacity.
Exploring Most Cost-Effective Options for Future
Between June when the Legislature approved the money and now, the City, County and State have explored ways to work together to ensure they spend the money cost-effectively. The county hired a consultant to explore the merits of do-it-yourself dredging vs. hiring a contractor. At the moment, the partners lean toward the contractor approach. It offers long-term flexibility as they explore future needs around the lake.
In addition to the $30 million from the State, the City of Houston allocated $6 million from money left over from Harvey disaster recovery funds. The County also allocated $10 million in its flood bond for dredging.
Initial Disposal Site Already Approved
The Army Corps approved Barry Madden’s property as a disposal site for the spoils. Madden’s property is opposite River Grove Park. That puts it miles closer to the Mouth Bar than previous placement areas used by the Corps. That should reduce costs by reducing the need for booster pumps and fuel.
The pieces of the puzzle are starting to come together.

If you boat between the San Jacinto East Fork and Lake Houston, perhaps you’ve noticed it’s a little harder getting from A to B lately. The San Jacinto East Fork Mouth Bar has grown approximately four fifths of a mile during the last two storms and the channel depth has decreased 6X.
These three pictures tell the story dramatically.
I took the first after Hurricane Harvey and the second after Tropical Storm Imelda. The third comes from Google Earth BEFORE Harvey.
East Fork Mouth Bar After Harvey
Looking north toward Kings Point from the East Fork of the San Jacinto River after Harvey. Note fresh sand several feet deep everywhere. Photo taken 9/14/2017, two weeks after Harvey.
East Fork Mouth Bar After Imelda
Extent of East Fork Mouth Bar After Imelda. Photo taken 12/3/2019.Note in this photo how much closer the sandy bottom is to the surface throughout the entire area.
Pre-Harvey to Post-Imelda Growth
Satellite image from January 2017 BEFORE Harvey. Yellow line represents approximate growth in East Fork Mouth bar between then and today – about four fifths of a mile.For alignment purposes, note the tip of the Royal Shores Lake in the first aerial photo and Royal Shores in the second.
Boater Josh Alberson says the maximum channel depth in this area decreased from 18 feet after Harvey to 3 feet after Imelda.
Geologic Change on a Human Time Scale
Note how the leading edge of this growing bar is now almost even with the entrance to Luce Bayou. When we get another storm like Imelda, the East Fork Mouth Bar could block the Interbasin Transfer Project from delivering water to Lake Houston.
Changes like these usually happen on a geologic time scale. They happen so slowly, humans can barely perceive them during the course of a life time. However, Harvey and Imelda produced this change in two years. They provide us with a rare glimpse of a living planet in our own backyard.
If you have children, grandchildren or students, please share these photos with them. They make valuable life lessons about the power of moving water and respect for Mother Nature. They may also stimulate curiosity in Earth sciences and engineering.

Instead of accelerating completion of detention ponds on Woodridge Village as Perry Homes promised, the company appears to have pulled all excavation equipment from the site. Contractors who were supposed to have been working on detention pond N-1 have gone…BEFORE they finished S2 and BEFORE they finished a berm sealing off the southern portion of the site at Fair Grove Drive.
Equipment Left Site Instead of Beginning On Next Pond
Perry Homes had promised in its letter to accelerate construction, but this will slow it down – if they ever return. The only work being done Friday? Removal of some dead tree piles on the northern portion of the site.
Jeff Miller took all the pictures and videos below on Friday and Saturday. He also monitored work on the site and provided this scouting report.
Looking south toward Taylor Gully and the Harris County Line along the eastern embankment of the S2 detention pond.The channel along the eastern portion of Taylor Gully is now lined with concrete. The spillway into the S2 detention pond has been widened and smoothed. The S2 detention pond is behind the camera position. Looking East.Looking west across S2 detention pond. The dirt that eroded into the pond has been scooped back up onto the banks and compacted.Still no grass on the banks, however, so it could all wash back in with the next big rain.Looking north. The grassy area in the background was supposed to have contained the N3 detention pond. However, contractors have simply excavated a channel from the northern section directly into Taylor Gully so now runoff can accumulate even more quickly.Contractors widened and concreted the Taylor Gully channel along the eastern side of Woodridge Village. But they left the most vulnerable part of the channel without concrete. At the end corner by the telephone poles, water comes from the left. But no concrete protects the area where the water makes a sharp 120 degree turn. Expect water to erode behind the concrete and peel it away in the next big rain.
Woodridge Village Section One Now a Virtual “Ghost Town”
This weekend, Woodridge Village Section One looked like a ghost town, not a bustling construction site with people working against a deadline.
Heavy construction equipment used to be parked by dumpster in the background. Now it’s nowhere on the property. Looking south. Another view of the same area that held construction equipment. It’s all gone and the berm sealing the site off from Fair Grove Drive is missing.
Still Removing Dead Trees/Mulch on Northern Section
On Friday, only smaller equipment turning tree piles into mulch remained.
Perry Homes Intentions Now a Mystery
As of Sunday morning 12/22/2019, no equipment actually working on construction could be seen on the site. The excavators and dump trucks parked at Fair Grove for months have been removed.
Perry Homes is NOT accelerating completion of detention ponds as it promised the City of Houston.
Instead, Perry Homes has thrown a curtain of silence around this job. It’s hard to know what their intentions are. At this point, Perry Homes’ lawyer J. Carey Gray has as much mud on his face as Elm Grove residents had in their homes.
The only thing we can say with certainty: Lowering flood risk for the people of Elm Grove does not seem high on Perry Homes’ priority list.
For Sale And For Lease Signs Serve as Christmas Yard Decorations
Meanwhile, a drive down Shady Maple or Village Springs, the two streets that border Taylor Gully, revealed residents’ attempts to salvage Christmas from the chaos of floodwaters. Dumpsters and debris still line the streets. Some people still live in trailers in their driveways. No apple cider around the hearth for them. They’ll be lucky to find space for a table top Christmas tree. For Sale and For Lease signs outnumber Christmas yard decorations ten to one.
On a street called Right Way in North Kingwood Forest, I found nine For Lease signs in a row. Sad reminders of Imelda and Perry Homes.Only three months ago, these homes were filled with families who flooded for the second time.
Kathy Perry Britton just added another credit to her resume, “The CEO Who Stole Christmas.”

Water Supply, Not Just Flood Mitigation, An Issue
Dredging affects more than flood mitigation. It also affects water capacity for Lake Houston. The lake supplies drinking water for 2 million people. The Interbasin Transfer Project will soon bring 500,000 gallons per day from the Trinity River. But a growing East Fork mouth bar could soon block Luce Bayou. That’s where the water will enter the lake to be used by the Northeast Water Purification Plant.
West Fork Also Plays Role in Water Transfer
That’s also why the West Fork must remain clear. It brings water, when needed, from Lake Conroe.

Perry Homes Pulls Excavation Equipment From Woodridge Village Before Finishing Detention Ponds

Contractors who were supposed to have been working on detention pond N-1 have gone…BEFORE they finished S2 and BEFORE they finished a berm sealing off the southern portion of the site at Fair Grove Drive.
S2 Pond Still Not Complete; Does Not Meet Regs
On October 17th, a lawyer for Perry Homes’ subsidiaries sent a letter to the City of Houston Attorney promising that the company would “accelerate” completion of detention ponds. Even though Perry Homes had already substantially completed Detention Pond S2, it took Perry 63 days to restore it to its pre-Imelda condition. Worse, contractors left before the pond met the regulations in Montgomery County’s Drainage Criteria Manual. It still doesn’t have fencing, service roads around its entire perimeter, or grass on its banks. Finally, it holds water when regulations call for a dry bottom.
Equipment Left Site Instead of Beginning On Next Pond
Perry Homes had promised in its letter to accelerate construction, but this will slow it down – if they ever return. The only work being done Friday? Removal of some dead tree piles on the northern portion of the site.
