State of the Bayou

Downed Trees. New Channel. New Riprap. Washed Out Sidewalks, Beavers, and Turtles

But Some Banks Naturally Rebuilding

Does It Make Sense to Repair?

We finally had a chance recently to float down beautiful Buffalo Bayou to see how things have changed. Our trip took us past Memorial Park in the middle of Houston. We also biked along the bayou through Terry Hershey Park far upstream in west Houston below the dams to see what was happening there.

The good news is that some of the high banks that had slumped in Memorial Park and the Hogg Bird Sanctuary during the Memorial Day 2015 flooding are naturally rebuilding.

The bad news is that the River Oaks Country Club has added more riprap to the south bank, hard armoring the bank with ugly, damaging concrete rubble, including where it should not be.

Nature’s Miraculous Way of Restoring. For Free.

Houston has had multiple record-breaking rains and flooding since the spring of 2015. When Buffalo Bayou overflows its high banks, as it did in the Memorial Day flood of 2015, the banks in places sometimes slump or slide away. This happens when the overflowing water seeps through the ground and saturates layers of sandy clay that liquefy, sometimes causing the bank to give way. Buffalo Bayou is 18,000 years old, and this has been happening for a very long time.

This natural tendency to slump is one reason why we think attempting to engineer these banks as proposed by the $6 million Memorial Park Demonstration Project won’t work. It’s also the reason why we think building and repeatedly repairing sidewalks at the bayou’s edge is wasteful and foolish.

Cool Off With Geology Classes On The Bayou

A Good Time for Floating with Tom Helm

August 13, 2016

You may think it’s way too hot to go outside. But it’s actually much cooler down on the bayou, thanks to the water and the shade from overhanging trees.

Also it’s free of mosquitoes since the damselflies eat them up. Nature works that way. Bats eat mosquitoes too. Mosquitoes don’t breed in flowing water anyway.

So now is the perfect time (unless it’s raining) to cool off and learn about the amazing geology of one of the last natural stretches of our 18,000-year-old Buffalo Bayou as it flows past Memorial Park.

Float for a couple of hours through this historic nature area with geologist, naturalist, and river guide Tom Helm. Tom will explain the ancient sandstone formations and high Pleistocene bluffs, the patterns in the sand, why the river changes course and how sediment taken away from one side gets deposited on the other. And much more. See mole cricket tracks and watch diving hawks! Witness the grace of a great blue heron flying in front of your canoe!

Right here in the middle of Houston.

Tom takes care of everything. Look under Classes at the top page of this website. Or contact Tom directly. Scheduling is flexible so arrange a time that suits you and your family and friends.

Get outside, have a good time, and learn something new! The water is low now so the sandstone formations and sandy banks are visible.

But if it’s raining or the flow is too high, classes will be postponed.

Update on Puzzling Project to Bulldoze Wild Buffalo Bayou

Damaging, Expensive, Contradictory Plan Still Threatens

Conflicts Still Apparent, Purpose Still Unclear

No Permit Yet

October 8, 2015

The Harris County Flood Control District has responded to largely critical public comments to the Army Corps of Engineers about Flood Control’s misguided project to destroy one of the last natural stretches of Buffalo Bayou in Houston, a most remarkable asset to have in the middle of a city. The Corps is reviewing the Flood Control District’s responses, says Jayson Hudson, who has been the Corps’ Galveston District project manager for the permit application.

Flood Control must apply for a permit from the Corps of Engineers because the Clean Water Act requires the Corps to ensure that projects on federal waters do not damage the health of our waters. Federal waters are defined as navigable streams (Buffalo Bayou) up to the Ordinary High Water Mark, their tributaries and adjacent wetlands, all of which form the great living veins and arteries of our limited water supply. Some studies argue that all riparian areas , the highly biologically diverse natural gardens and forests along stream banks so vital for clean water, should be considered protected wetlands .

But It’s Best to Leave the Bayou Alone, Says BPA’s Water Quality Director

Feb. 5, 2015

We lost track of the number of times our jaws dropped listening to Steve Hupp present the Bayou Preservation Association’s argument for destroying one of the last natural stretches of Buffalo Bayou in Houston.

Hupp, who was speaking to the Briar Forest Super Neighborhood council on Jan. 20, is the water quality director for the BPA, which was founded in the 1960s to protect the natural banks of Buffalo Bayou from the bulldozers of the Harris County Flood Control District. Hupp lamented that a representative of Flood Control wasn’t there to help him make his case for bulldozing and dredging some 80 percent of a healthy stretch of our wild, southern bayou for more than a mile in and around our public Memorial Park, including the great cliffs of the Hogg Bird Sanctuary. This $6 million boondoggle, touted as “bank restoration and stabilization,” is called the Memorial Park Demonstration Project (MPDP). Demonstrating exactly the wrong thing to do for erosion control by razing the riparian buffer, the project will destroy the bayou’s ecosystem. According to the BPA, the bayou will be re-engineered to “a more natural state.”

Briar Forest, which is south of Buffalo Bayou between Gessner, Westheimer, and Dairy Ashford, has been fighting its own battle with Flood Control over a plan to destroy a significant amount of forest to create stormwater detention basins.

City Council Member Oliver Pennington was at the meeting. Pennington, who is running for mayor, represents District G, which includes Briar Forest way out there and much closer into town, the south bank of Buffalo Bayou in the “bank restoration” project area. The south bank, which is half of the project, is owned entirely by the River Oaks Country Club, founded in 1924, of which Pennington is a member and which is donating $2 million or one-third of the projected cost of the “stabilization” project. The club is in the process of digging up and rebuilding its golf course, which over the decades has encroached on what was once thick riparian forest, moving closer and closer to the edges of the high banks of the bayou.
