High Bank on Bayou Damaged by Bike Riders
Fools Dug Up Vegetation and Drove Boards Into Top of Bluff
But Boy Scouts Do More Good Deeds, Plant Vegetation
March 7, 2018
Riding a bike along the edge of a cliff above a river is bad enough. Even walking on top of a high bank can be damaging. But the high banks of Buffalo Bayou in Houston’s Memorial Park are already stressed and attempting to recover from the overbank flooding that came with Harvey last summer. Large sections of the bank slid away, taking down trees and vegetation. With time, however, the vegetation will grow back, the downed trees will collect sediment, and the banks will rebuild.
Now that recovery will be much more difficult. In the past weeks, off-road cyclists built a bike jump and wooden ramp right at the very edge of the bank near the main tributary draining the center of the park. This is very near the Bend in the River that Save Buffalo Bayou and photographer Jim Olive have been documenting through the seasons for the past four years.
The culprits apparently removed vegetation, dug holes, and drove large boards into ground. And then, of course, they’ve been pounding the edge of the bank with their bikes. They also dug up dirt to mound it into a jump further down the bank.
Representatives of the Greater Houston Off-Road Biking Association (GHORBA) condemned the construction.
“We would never approve this type of activity,” said C.J. Bernard, trails director for the biking association, in an email. “For anything we do at GHORBA related to trail development and maintenance, we follow the IMBA Sustainable Trails guidelines which highly emphasizes ways to identify potential erosion concerns and provides ways to eliminate and/or minimize.” (IMBA is the International Mountain Bicycling Association.)
“Most likely it is from a mountain biker that isn’t associated with GHORBA, as our trail stewards must approve features before they are built and this one, to my knowledge, was not,” wrote Christy Jones, president of GHORBA, in an email.
The dirt paths through the woods along Buffalo Bayou south of the Picnic Loop in Memorial Park are unofficial trails. However, they are much used by walkers and runners. Other trails in the park are officially open to bike riders as well as others. The neighboring Arboretum, however, does not allow bikers on its paths.
A representative of the Memorial Park Conservancy said the structure would be removed. “We are very grateful that you alerted us to this and will assess and remove the structure ASAP,” wrote Cara Rudelson, chief operating officer of the Memorial Park Conservancy, the private nonprofit organization running the public park. “We always have our eyes out for unauthorized use of the unofficial trails!”
Boy Scouts Plant Riparian Rebar on Bank of Buffalo Bayou
In the meantime, some more positive news: members of Boy Scout Troop 55 are doing good deeds again. This time, under the leadership of Boy Scout Austen Furse, who developed the plan for his Eagle Scout project, they planted 200 buckets of native eastern gamagrass on the upper banks of the ugly stormwater outfall, formerly a nature trail, also known as the Woodway Boat Launch, in the Old Archery Range of Memorial Park west of Loop 610. This happened Saturday morning, March 3.
Eastern gamagrass is an herbaceous stabilizer plant, described as “riparian rebar” and a “big, green leafy cousin of corn.” Though slow to establish, once established, eastern gamagrass can grow to six feet or more and has “extremely good root stability,” according to Your Remarkable Riparian, a field guide to riparian plants found in Texas.
Take note, property owners contemplating ugly and damaging concrete riprap for bayou banks.
Let’s hope the young gamagrass doesn’t get mowed down.
Austen is planning to photograph the site every week or two to document the results, says his mother, Anne Furse.
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?
Sept. 1, 2016
Updated Sept. 11, 2016
You could not step twice into the same river. Heraclitus
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.
Can An Urban Stream Restore Itself?
Yes, With Room to Move. Free Rivers Are Healthier and Better for Flood Control

By Susan Chadwick, Executive Director, Save Buffalo Bayou
This article is adapted from a presentation made at the Southwest Stream Restoration Conference in San Antonio, Texas, on June 2, 2016.
Save Buffalo Bayou is a non-profit organization founded two years ago to fight a public project described as a “restoration” project on one of the last natural stretches of Buffalo Bayou as it flows through the middle of Houston, past 1,500-acre Memorial Park and another 15-acre public nature preserve, the Hogg Bird Sanctuary. Since then our organization has expanded into broader, related issues. But today’s topic is restoration.
Here are some of the most common responses I would get when I would say that this mile-long plus stretch of the bayou is natural, along with what were some of the most common defenses of the project.
The river’s not natural because the river changes.
It’s not natural because it’s been altered by high runoff from urbanization.
Trees fall into it.
It has terrible erosion problems. Look at those steep high banks!
It’s terribly eroded. Look at those sandy banks!
It’s eroding terribly. Sediment from the banks in Memorial Park washes up on the sidewalks of Buffalo Bayou Park we built downstream in the floodway right next to the river.
All that sediment carries bacteria. If we stop the banks from eroding so much sediment, we will reduce the bacteria. (Although sediment-laden Buffalo Bayou is less polluted than White Oak Bayou, which runs relatively clear and extremely foul due to being encased in concrete.)
And of course the big one: the river needs to be stabilized because it moves around.
Then there’s the argument, both implied and explicit, that prompted me to select this topic for presentation today: an urban stream cannot restore itself.
A Profound Misconception About How Nature and Rivers Work
All of those statements, of course, indicate a profound misconception about nature, about how a river works and how rivers benefit us.
A river is a living symbol of change. A living system. A dynamic process of nature that works for our benefit. Even the simple grains of sand work on our behalf to cleanse the water.
It’s for the Birds
Report on Plans for the Hogg Bird Sanctuary on Buffalo Bayou
May 11, 2016
First the positives about the presentation Monday evening, May 9, by the Houston Parks Board about plans for the little-known 15.56-acre nature preserve on Buffalo Bayou known as the Hogg Bird Sanctuary.
The sanctuary at the end of Westcott Street south of Memorial Drive is probably better recognized as the mostly impenetrable woods next to the parking lot for the Houston Museum of Fine Arts’ Bayou Bend Collection and Gardens, located across the bayou, accessible by a footbridge. Bayou Bend is the former home of the Hogg Family, who developed River Oaks and in 1924, along with partner Henry Stude, sold at cost to the city the 1,503 acres that became Memorial Park. (The Hogg Brothers also sold to the city at cost 133.5 acres of land intended to be part of Hermann Park. In 1943 the city sold that land for the establishment of the Medical Center, which provoked the continuing ire of their sister, Ima Hogg.) Ima Hogg, a cultural and civic leader and one of the city’s most revered philanthropists, donated the family house and gardens to the museum in 1957 and then donated to the City of Houston the woods on the north side of the bayou as a nature preserve.
Ima Hogg a Defender of Nature and Public Parks
Ima Hogg, who died in 1975, was also an ardent conservationist, early civil rights activist, mental health activist, and defender of park space for the public, in particular Memorial and Hermann parks. In her letters to city officials over the years, available in the archives of the Museum of Fine Arts, she described her firm belief that woodland parks should be kept as natural as possible and criticized in a 1964 letter to then Mayor Louie Welch, who famously thought public parks unnecessary, the “alarming situation” of rapidly diminishing park areas in Houston and “throughout America,” including through construction in the parks by “worthy institutions” that really ought to look for building sites elsewhere, she wrote. Miss Ima was still angry that the city had “relinquished so much of the acreage” in Memorial Park for highways and a golf course and in an earlier letter to then city director of public works, Eugene Maier, demanded that the money the city received from the state for the highway land be used to acquire and improve additional park sites. Let’s guess that probably didn’t happen.
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.

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 .
The Piles of Concrete Came Down
Country Club Armors High Banks with Chunks of Rubble
August 12, 2015
For months we watched with suspense the towering piles of concrete riprap. They hung heavily over the edge of a high bank on the south side of Buffalo Bayou near the downstream end of one of the loveliest natural stretches of the bayou in the city. It’s a long stretch of the bayou that the Harris County Flood Control District wants to bulldoze and “restore” to a “more natural state,” so we were apprehensive.
A row of small telltale colored flags had first appeared near the waterline here and upstream at the upper limit of the area targeted for flood control’s highly destructive Memorial Park Demonstration Project.
The south bank of the nearly 1.5 mile project area is owned by the River Oaks Country Club, which is a one-third partner in the $6 million public project initiated and promoted by the Bayou Preservation Association. The club, which has nearly completed a renovation of its golf course on the bayou, had long threatened to armor its banks with riprap if the “stabilization” project didn’t go through.
And now the club has carried through on its threat, laying down black plastic sheeting on the steep banks at those two locations downstream and upstream, distributing chunks of concrete on the slopes, and covering the blocks with dirt. Club member Steve Lindley, who is overseeing the riprap work as well as the golf course upgrade for the club, said that the plastic sheeting is porous and biodegradable and that club plans to seed the dirt with grass to keep it from washing away and eventually to plant it with native vegetation such as chili pequin.
Leave It Alone: Buffalo Bayou Will Naturally Repair Itself
Opponents of the Memorial Park Demonstration Project Say Buffalo Bayou Is Fine Post-Flood
By Dianna Wray, Houston Press, Wednesday, June 10, 2015
After the rains started coming down on Memorial Day weekend, geologist Bill Heins, an ardent opponent of the Memorial Park Demonstration Project, couldn’t stop thinking about what was happening as the waterway continued to swell and slop over its usual banks along the last natural stretch of Buffalo Bayou that exists in Houston.
The flood waters haven’t fully receded yet, but both those in favor of the project and those against it have been out on the bayou looking for anything to back up their arguments. Project proponents point to signs of erosion on the soggy banks as evidence that we need this project. Those against it, including Heins, argue that the banks are showing signs of only minor erosion and that the evidence so far shows the natural system of the bayou — even during a record-setting flood — is working perfectly, meaning the Memorial Park Demonstration Project is unnecessary.
