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.
It’s Not Dead Yet
Flood Control Still Pushing Costly, Destructive “Stabilization” Project on Buffalo Bayou
July 31, 2016
It’s a pointless, wasteful, ill-conceived, and maybe illegal project to rip up and raze trees and plants and wildlife habitat, dig up the banks, plug up tributaries, dredge and reroute the channel along one of the last natural stretches of Buffalo Bayou in Houston. This is a dreamy stretch of the river in the middle of the city, filled with beaver, otter, alligators, fish and flying creatures, and even edible plants. It flows for more than a mile past our great public Memorial Park, a natural detention area and significant geologic site that features very old high bluffs and sandstone formations. All of which would be obliterated.
And after almost three years of adamant public opposition, the Harris County Flood Control District is still promoting the project, which will cost the taxpayers at least $4 million plus, not including future costs of maintenance and repair.
It’s mystifying why they want to do this, why they think it would even work, why they don’t realize that the bayou would wash it away or that it would simply all slump away, as has happened in Buffalo Bayou Park downstream, where taxpayers are footing the ever-mounting bill for constantly repairing the banks dug up and stripped of trees and vegetation by Flood Control.
Do They Not Have More Urgent Problems?
Surely, the flood control district has more urgent problems that require our hard-earned tax money. Harris County is one of the most flooded places in the country. And this project, billed as a “stabilization” and “bank restoration” program, will do nothing to address flooding and could even make it worse. The county should focus on the hundreds of miles of channelized bayous and streams unwisely covered in now-aging concrete that should be restored to something more natural and beneficial.
The project, called the Memorial Park Demonstration Project, was first proposed in 2010 by the Bayou Preservation Association under then board chair, Kevin Shanley, landscape architect and principal with SWA Group, the firm responsible for the ugly, obtrusive bridges, collapsing sidewalks, poorly-functioning dog park and non-functioning faux Hill Country fountain and stream in Buffalo Bayou Park.
How Old Is Buffalo Bayou? Where Does It Come From?
Geology Lessons on the Bayou
March 27, 2016
Want to learn about the geology and natural history of Buffalo Bayou?
Save Buffalo Bayou is partnering with professional geologist Tom Helm, who also happens to be an outstanding naturalist and river guide, to offer floating classes on the geology of our 18,000-year-old mother bayou.
Paddle with Tom on a two-hour canoe trip down Buffalo Bayou and see some of our Pleistocene natural history right here in the middle of Houston. Learn all about the formation of the bluffs and sandstone rocks during the last ice age. See examples of depositional environments and fluvial processes. Find out why the banks are sandy and how sand moves downstream, why the river looks the way it does, and much more.
Where, When, Cost
The classes start at the Woodway boat launch in Memorial Park and float past the park and the Hogg Bird Sanctuary, through the historic natural area targeted for destruction by the Harris County Flood Control District. Multiple stops will be made along the way to examine features of interest.
The schedule depends on class size. One to four persons can be scheduled any day of the week, usually with no more than 48 hours’ notice. Groups larger than four persons (up to 30 persons maximum) are accepted only on weekends. These larger weekend groups need to schedule at least one month in advance.
Cost is $50 per person, which includes canoe and equipment, and light refreshments at the end. Discounts are available for academic faculty and students.
Note that the classes will be not take place if the flow of Buffalo Bayou is greater than 300 cubic feet per second (as measured by the Piney Point USGS gauge). At water levels above this, the sandstones are mostly obscured. If a trip is cancelled due to high water, students have the option of rescheduling or receiving a full refund.
For more information, contact Tom Helm.
Some Things We Learned Already: Why Mud Stinks
We floated with Tom recently for a preview of the geology class. Among the things we learned is why some of the mud stinks. The mud and the sand are filled with layers of organic matter, leaves mostly, and as the organic matter decomposes, it smells like … decomposing stuff. But it also builds soil for future vegetation. This process produces the mysterious oily sheen that you see floating on top of the mud sometimes.
We also learned to tell mud from sand from silt. (Hint: it’s a matter of the size of the grains.) Tom showed us how geologists rub the mud between their thumb and fingers to feel the size of the grains.
We studied the patterns in the sand, watched the grains of sand moving in the water, and learned about eddies and sediment deposition and transport. We saw a lot of animal tracks.
We learned to put the constantly changing bayou in the context of its natural process.
In every outthrust headland, in every curving beach, in every grain of sand there is the story of the earth.

Travel down the remarkable historic stretch of our 18,000-year-old bayou proposed for “restoration” by the Harris County Flood Control District and the City of Houston. The $6 million project, violating virtually every Best Management Practice for riparian areas, would pointlessly destroy and rebuild over 1.25 miles of a naturally-functioning bayou as it flows past Memorial Park and the Hogg Bird Sanctuary on the north and the River Oaks Country Club on the south.

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 .
Operation Save Buffalo Bayou: Banners, Signs Erected During Big Regatta Saturday, March 7
March 8, 2015
Defenders of Buffalo Bayou traipsed through clumps of wild chives and violets on the banks of the bayou Saturday, March 7, in order to hang colorful banners from bridges and trees and set out signs informing more than a thousand participants in the annual Buffalo Bayou Regatta about the grave threat to our wild bayou.
Operation Save Buffalo Bayou was a huge success as competitors paddling down the bayou waved and shouted “No bulldozers!” and “Leave it natural!” to members of the Buffalo Bayou defense team sitting on the banks in the project area.
Bayou defenders also handed out informational flyers at the end of the race in Sesquicentennial Park adjacent to the Wortham Center downtown and engaged participants and officials in conversation.
The regatta was organized by the Buffalo Bayou Partnership (BBP), a non-profit organization in charge of developing the $58 million Buffalo Bayou Park between Memorial Drive and Allen Parkway downstream of the project area. The partnership officially supports the $6 million plan to bulldoze one of the last natural stretches of the bayou as it flows past Memorial Park in the middle of Houston.
Sand on the Sidewalks
BBP President Anne Olson wrote a letter of support for the destruction project to the Army Corps of Engineers in June 2014 saying that the plan would “significantly prevent” the bayou from “depositing silt on Buffalo Bayou’s downtown parks and trails.” She also claimed that the project, known as the Memorial Park Demonstration Project, would demonstrate “a prototype that can be employed by bayou property owners who currently remedy their property erosion by all different types of inappropriate stabilization methods.”
In fact the amount of silt and sediment contributed by the historic nature area targeted for destruction by the Harris County Flood Control District is minimal. But the project itself would likely greatly increase the sediment flowing downstream as a result of dredging the bayou, removing trees and plants, and breaking up the soil structure of the banks.
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.
