Harris County Flood Control District has quietly started repairs to two more Kingwood Drainage Ditches. The first is G103-33-01, the ditch between Fosters Mill and Kings Point that enters the river near the mouth bar at Scenic Shores. The second is the Kingwood Diversion Ditch, G-103-38-00. It runs down the west side of Woodland Hills, crosses Kingwood Drive by the fire station, then descends to the lake between Trailwood Village and Forest Cove.
Work In Progress as of Monday 5/11/2020

Work on Diversion Ditch Expected to Start This Week
According to Beth Walters of Harris County Flood Control, work on the Diversion Ditch should start this week. Below are several pictures taken of severe erosion that threatens homes and trails.

Photo taken in 2009.Kayakers have dubbed this area the Kingwood rapids. During floods, it offers the only white water experience in Kingwood.
Ditch maintenance includes erosion repairs, silt buildup removal, mowing, de-snagging (removing downed trees), and removing collapsed drainpipes.

Additional details are not yet available on the length of time repairs will take.
Thursday evening, I posted about a drainage ditch on the western edge of Woodridge Village in Montgomery County that Perry contractors had partially blocked off.

With storms and possible flash flooding predicted for Friday and Saturday, nervous residents worried about possibly flooding a third time and expressed their concerns to the contractor. Luckily, the current batch of Perry Homes’ contractors proved far more responsive than the last.
Contractors Clean Out Ditch Friday Morning Before Storm
Friday morning, they started cleaning out and widening the ditch. The rains came that night and into Saturday morning. And the nervous residents breathed a sigh of relief. There was no visible flooding, according to Jeff Miller, who toured Adams Oaks Saturday morning as rain ended.
Miller sent in these pictures of work in progress on Friday morning before the rain.

Miller’s pictures make it apparent that the ditch which emptied Adams Oaks is becoming part of a much bigger ditch that extends south from Detention Pond N2. In fact, the old ditch looks as though it will become the backslope interceptor swale for the new, bigger ditch, which is really the tail of the N1 detention pond that helps connect it to N2 and Taylor Gully. See map and photo below.
The newly “rehabilitated” ditch ran along the western (left) edge of Woodridge Village between N1 and N2.
Photo by Jeff Miller taken Saturday morning, shows that the old ditch, left, became the backslope interceptor swale for a much bigger new ditch (right.) This should improve Adams Oaks drainage. Photo take Saturday, 5/16/2020 after about 2 inches of rain.
Regardless, the contractors responded to concerns and scrambled to connect Adams Oaks with their drainage system before the storm.

As additional detention ponds take shape, they will help hold water back from S1 and S2. That may help them prevent overflowing which flooded Elm Grove twice last year.
Status of Sale to County/City
That’s important. By Houston law, any financial transaction greater than $50,000 must be approved by a vote of City Council. And the Council did not consider the donation of land to Harris County Flood Control this week for a Perry deal this week.
You may remember that that was one of two conditions Harris County put on a purchase deal with Perry Homes. And Friday was Perry Homes’ deadline for consummating a deal. However, if the City and County can work something out before Perry finds a private buyer, I assume the land would still be for sale.

Aerial photos taken on 5/11/2020 show wastewater on neighboring properties outside the Triple PG mine in Porter are higher than in the mine’s settling pond. If heavy rains materialize this weekend as predicted, that wastewater could be flushed downstream into the drinking water for 2 million people.
Mine Has History of Dumping and Pumping
Earlier this year, I photographed the mine pumping wastewater from its settling pond toward the neighboring properties. A TCEQ investigation confirmed that wastewater had exited the mine for the fourth time in a year. Investigators found that the wastewater had levels of suspended solids 676% higher than water from nearby White Oak Creek. But they also found that elevation differences had confined the wastewater and kept it from entering the wetlands near White Oak Creek.
Heavy Rains, Flash Flooding Could Flush Water Downstream
However, heavy rains predicted for later today and Saturday could change that. Jeff Lindner, Harris County Flood Control meteorologist says rainfall rates of 1-3 inches per hour will be possible and there is a slight (10-20%) risk of flash flooding, both days. Isolated totals could reach 6 inches on Saturday, he predicts.
How High Is Water On Neighboring Properties
So how high is the water outside the mine compared to inside?
In the photo below, note the two sets of arrows on either side of the road. The strip of trees under the upper right arrow does not belong to the mine. However, the land under the lower right arrow does belong to the mine. I included the second set of arrows because they are closer to the camera and that makes it easier to see the elevation difference in the water. Notice how much higher the water is on the right than on the left relative to the road.

Photo taken 5/11/2020.Looking east over flooded properties (inside tree-line) that neighbor mine.Photo taken 5/11/2020.Terms of a temporary injunction restrict the mine from using its dredge. So the mine has started dry (or semi-dry) excavation. That meant removing wastewater from this pit.Photo taken 5/11/2020.
On January 20, 2020, I photographed the mine pumping water out of its settling pond toward adjoining properties. See below. The pit above can be seen in the upper left of the photo below.
See the pipe cutting diagonally from the middle of the frame to the lower right. Also note, the pond in the upper left of this image corresponds to the pond in the foreground of the image below.Note water level on January 20, 2020By February 13, three weeks later, that pond was largely empty. It is common for mines to pump water from one pond to another.But illegal to pump water outside the mine.
Why Mines Should Not Flaunt Rules
If approaching storms flush sediment- and chloride-laden wastewater downstream, it will end up in the San Jacinto East Fork and Lake Houston, the source of drinking water for 2 million people.
This underscores the need for the state legislature to pass laws that move mines out of the floodway. The Triple PG mine actually sits at the confluence of two floodways. That makes it vulnerable and dangerous…especially when an operator apparently flaunts rules designed to protect the safety of the public.

Left unrepaired, such erosion can destroy property and trails. These repairs are part of HCFCD’s ongoing maintenance efforts.
Here’s a list of planned maintenance projects on other ditches around the Kingwood area.

Perry Contractors Opened Up Woodridge Ditch Hours Before Rain Struck
Thursday evening, I posted about a drainage ditch on the western edge of Woodridge Village in Montgomery County that Perry contractors had partially blocked off.
Last year, residents of Adams Oaks, a Porter subdivision that borders Woodridge Village, say that alterations to that same drainage ditch contributed to flooding dozens of homes twice. Recently, the encroachments on the ditch became more pronounced as construction on the Perry site kicked into high gear.
With storms and possible flash flooding predicted for Friday and Saturday, nervous residents worried about possibly flooding a third time and expressed their concerns to the contractor. Luckily, the current batch of Perry Homes’ contractors proved far more responsive than the last.

The purchase is not on the Harris County Commissioners’ Court agenda for next week.
