Discover Scenic Secrets of Buffalo Bayou with Reporter Brandi Smith and Geologist Tom Helm
Nov. 17, 2018
KHOU television (Channel 11) is airing a four-part series on the hidden wilderness of Buffalo Bayou in Houston. Thank you, KHOU. Titled “Brandi on the Bayou: Buffalo Bayou’s Hidden Wilderness,” the series is reported by KHOU’s Brandi Smith and airs Tuesday mornings at 6 a.m.
The first episode was broadcast Tuesday, Nov. 13, and featured geologist, river guide, naturalist, and Save Buffalo Bayou board member Tom Helm.
You can watch that first episode here. The next episode airs Tuesday, Nov. 20, at 6 a.m. and the final episode on Dec. 4. All the episodes will be available online.
But you don’t have to be a television reporter to float down Buffalo Bayou learning from Tom Helm.
Helm offers geology classes on the bayou. Find out more about the ancient history of this 18,000-year-old bayou, where it comes from, where it’s going, and why understanding the natural function of a dynamic river is important for effective flood risk reduction. Houston has rocks, and they are hundreds of thousands of years old!
In addition Helm offers a Happy Hour Bat Trip with refreshments on Buffalo Bayou in Buffalo Bayou Park.
Fall Photographing with Jim Olive, a Butterfly, and a Coral Snake
Monarch Discovers Daisies on That Bend in the Bayou. Big Coral Snake Slithers By
Nov. 17, 2018
We were a little delayed for a fall photo of that Bend in the River. We have been documenting this particular place on Buffalo Bayou through the seasons for more than four years. Photographer Jim Olive has obligations elsewhere these days, so we had to go with the day he could be here and the early morning weather on that day.
It was overcast and the flow was a high, a little under 2,000 cubic feet per second (cfs). It had been raining. Base flow in the bayou–normal flow when it’s not raining–is about 150-200 cfs.
But we waited and waited for the right moment, which is what a professional photographer does. We were standing on that same high bank in Memorial Park in the middle of Houston looking at the bayou flowing downstream with River Oaks Country Club property on the opposite bank. It was the same location, but as you can see if you look at Jim’s series of photos, it has changed through the years. Nature is not static.
Jim patiently shifted position and cameras and lenses. In the meantime, as usual, the photographer’s assistant wandered off, looking around, mainly for something edible to forage, and found some small puffball mushrooms growing on a rotting log. These little, round white mushrooms are variously described as “edible” or “choice.” The latter means delicious. “Edible” means they won’t kill you but they don’t necessarily taste good.
There were daisies growing on the high bank, and suddenly a big orange and black Monarch butterfly was fluttering there, feeding on the flowers on its way to Mexico. If you look closely, you can see where it had been in Jim’s photo.
As we were leaving we encountered the most beautiful coral snake on the path through the woods, right where we had seen a gigantic, sleeping king snake coiled up in the old, broken drainage pipes left over from Camp Logan, the World War I training camp and military hospital that occupied this land back then. This snake was “red and yellow, kill a fellow” and not “red and black, all right, Jack,” so definitely a coral snake. Turns out there are numerous variations of this ditty we learned as children to distinguish a highly venomous coral snake from the harmless milk snake. But a coral snake is not aggressive. And it can hardly bite. So not really dangerous at all unless you try to pick it up. This one was very large and shiny. Jim, an expert naturalist, thought maybe it had just shed its skin.
As for the little puffballs, they were okay. Ordinary, really. Not as delicious as the honey mushrooms or oyster mushrooms one can find growing in the park and along the bayou. The photographer’s assistant made a mushroom omelette.
How Katy Prairie Landowners Could Help Houston Fight Flooding
A Conversation with Jim Blackburn
Blackburn is an environmental lawyer, founder of the Bayou City Initiative, and co-director of the Severe Storm Prediction, Education and Evacuation from Disasters Center (SSPEED) at Rice University in Houston
Nov. 13, 2018
Q: How could preserving the Katy Prairie help minimize flooding?
A: Preserving the Katy Prairie alone can be useful and, with management, even private lands that are in cattle production can be useful. Mainly, it is about getting roots to penetrate the soil and water following the roots down into the ground. If you combine that will a small levee like what is in rice fields, you can perhaps pond another foot of water on the flat land. Together, the potential to store water is substantial.
Q: It’s been said that the Katy Prairie acts like a natural sponge. How does this work?
A: The roots of prairie grasses penetrate and break the soil, and in doing so, they create natural pathways. There is space around the root, and the water naturally penetrates. Those roots go down five or six feet. With roots in the soil, a very impermeable clay soil can become permeable.

KPFT Radio Accidentally Revives Dead Bayou Project
Five-Year-Old Interview About Memorial Park Demonstration Project Causes Confusion
Nov. 12, 2018
Well, we were confused too and a little upset as we listened to Evelyn Merz of the Houston Sierra Club being interviewed this afternoon on KPFT by Mike Honig of Thinkwing Radio about the Memorial Park Demonstration Project. That project would have stripped, dredged, and rerouted over a mile of Buffalo Bayou flowing past Memorial Park in the middle of Houston. The stretch is a historic nature area, one of the last remaining publicly-accessible forested stretches of the bayou in the city.
But the more we listened, the odder is seemed. Above all because the project is dead. Save Buffalo Bayou was founded over four years ago to stop this pointless project, which was promoted by Kevin Shanley of SWA Group, the landscape architecture firm responsible for Buffalo Bayou Park. (See the problems here.) The firm also happened to be on retainer with the Harris County Flood Control District, which became the official sponsor of the project, believing it had community support. Shanley was then the president of the Bayou Preservation Association. And for a time the project manager for the engineering firm hired to do the project was also on the board of the association.
In any case, it was a terrible, unpopular idea that served no good purpose and wasn’t going to work anyway. Based on a faulty analysis of bank collapse on the bayou, the project cost had increased from $6 million to $12 million. And after Harvey in August 2017, Flood Control District Director Russ Poppe, who inherited the project from his predecessor, publicly declared at a Bayou Preservation Association symposium that the project would not be going forward.
It turned out that the radio interview with Merz was five years old, and someone at KPFT had pulled it off the shelf to fill air time.
Merz, a member of Save Buffalo Bayou’s advisory board, was outside doing chores during the broadcast and just as surprised as everyone else to hear about it. She is also chair of the conservation committees of the Lone Star (Texas state) Chapter of the Sierra Club as well as the Houston Regional Group of the Sierra Club,
Station manager Don Freeman was apologetic, explaining the station operates “on a shoestring.” We urge everyone to support the nonprofit KPFT, a valuable public resource.
Birds of the Bayou
Report from Buffalo Bayou beat correspondent Janice Van Dyke Walden
Nov. 11, 2018
I had the great pleasure this weekend to take wildlife photographer Greg Lavaty canoeing down Buffalo Bayou to photograph birds. In the three hours of an overcast morning in the section of Memorial Park/River Oaks, Greg heard or spotted 33 bird species (full list below, along with some of his photos). Many thanks to Gary Studwell who helped crew so Greg could have a stable experience in fast water. It is truly wonderful that we have this wild corridor in the middle of our nation’s fourth largest city. Let’s keep it wild.

Growing, Growing Grass and Boys
Boy Scouts Help Nature on Buffalo Bayou
Oct. 31, 2018
On a fine Saturday morning last March, a small group of Boy Scouts got together with shovels and some potted plants and headed towards the public boat launch in Memorial Park near Woodway. Under the leadership of now 15-year-old Austen Furse, their goal was to plant gamagrass on the upper bank of Buffalo Bayou. The native grass is a stabilizer plant, known for its deep-rooted ability to hold the bank together.
Stabilizers are one of two basic categories of riparian plants that naturally work in succession to fix a sandy bank. There are colonizer plants that spread out near the water’s edge, sending out shallow roots. They prepare the way for the stabilizers with stronger, deeper roots. Stabilizers, which can be grassy or woody, help dissipate the erosive flow of the water and collect sediment to incorporate into the bank and hold it together. Riparian plants, including trees like willows and sycamores, generally work to absorb and cleanse water, among other benefits. The bayou, like other streams, naturally does this intelligent landscaping, although sometimes competing plants that aren’t supposed to be there intrude, fugitives from lawns and gardens, for example.
It was early March, and the bank was almost bare. Once a wooded nature trail, the public area had been stripped and graded more than four years ago to install a massive concrete outfall that drains stormwater from Post Oak Road. The mowed upper banks were planted with non-native, rapidly spreading Bermuda grass, the lower banks hardened with fake stone. And after three big floods, most recently the monster flow in Buffalo Bayou from Hurricane Harvey, the area was not looking so good.
This was Furse’s project to earn the rank of Eagle Scout. He is also a contender for the Hornaday Prize for natural resource conservation projects. The five boys helping him were all from Troop 55 of the Sam Houston Area Council. Within a few hours they had planted some 200 plants.
“Austen is a great young man,” said Daniel Walton, conservation coordinator for the Memorial Park Conservancy, the private nonprofit that manages the public park. “The way he handled it all was pretty impressive.”
Furse said that until a recent kayak trip, he had never really seen the bayou “which we drive by everyday.” He said it was “so cool.” That he saw “snakes and things.” This brief interview took place in October, in the midst of the growing gamagrass, as giant dragonflies buzzed like noisy, low-flying helicopters all around.
In the months that followed the initial planting Furse returned to monitor the grass, documenting its growth, sending reports, notifying Walton of potential threats like mowers and competing invasive weeds. At one point the bank was overtaken by an army of horseweed, which though native, can take over and monopolize disturbed areas, pushing out other native plants, points out native plant expert Katy Emde, a member of Save Buffalo Bayou’s advisory board. A variety of native plants supports a variety of insects, which in turn support a variety of wildlife.
“I think it is always interesting to see how plants that can be annoying are beneficial, nonetheless,” wrote Emde in an email. “It turns out that most native plants are beneficial, even if they are not our favorites.”
Furse also sent photos to Save Buffalo Bayou. And it was difficult to tell which was growing faster: Austen or the gamagrass.
Thank you, Austen Furse, and your helpers and advisors in Troop 55.
Did Straightening Upper Buffalo Bayou Make Future Residents More Vulnerable to Flooding?
Federal Project in Late Forties Reduced Bayou Capacity Upstream
October 29, 2018
By the early morning of Aug. 28, 2017, after about thirty hours of record heavy rains from Hurricane Harvey, storm runoff was rising so fast in the two federal reservoirs in west Houston that the Corps of Engineers feared the water would overflow the aging earthen dams. They made the unprecedented decision to open the dam floodgates, slowly at first and then, in the following days, much wider, as stormwater did indeed begin to spill around the northern end of Addicks Dam north of Interstate 10.
For most people living and working on Buffalo Bayou, the peak of the flooding had already passed on Sunday, Aug. 27, when the floodgates were still closed. That Sunday storm runoff draining from the paved and built city into the bayou below the dams sent anywhere from two feet to eight feet or more into homes and other structures built on or near the banks.
But when the dam floodgates were opened in the first hours of Monday, roaring floodwaters pouring out of the dams spread out and inundated neighborhoods built on the bayou’s floodplain below the dams for more than six miles to just below Beltway 8 (West Belt). Many of these homes had not flooded earlier.
The horrific flow through the open floodgates eventually reached more than 16,000 cubic feet per second (cfs). For much of Buffalo Bayou in west Houston flood stage is around 6,000-7,500 cfs.
As a result, many more homes and other structures flooded on the upstream stretch of Buffalo Bayou between the federal dams and Beltway 8 than downstream of the beltway. (Homes built in the reservoir flood pools behind the dams also flooded, but that’s another story.)
Blaming the Bayou. “Kinks” and “Bottlenecks” Downstream
This six-mile stretch of the bayou upstream of the beltway was straightened and shortened by the Corps of Engineers more than seventy years ago. The bayou downstream of the beltway remains a meandering stream, largely unchannelized, twisting and turning its way nearly to Shepherd Drive. Below Shepherd the bayou was stripped and channelized in Buffalo Bayou Park by the Corps in the Fifties. From there it flows along a heavily altered route through downtown, eventually becoming the Houston Ship Channel.
In the wake of this disastrous flooding upstream of the beltway, distraught and shell-shocked property owners, many of them without flood insurance and dealing with severe losses, have been blaming the “kinks” and “bottlenecks” in the meandering bayou below Beltway 8 for flooding their homes. The belief is that the meandering bayou constricted the flow and caused water to backup and flood property upstream. The common complaint is that the bayou downstream is too narrow and is “like a hose” that gets a “kink” in it, causing the water to stop and back up.
Who Owns the Bayou?
Rights, Responsibilities, and Flooding Your Neighbor
Sept. 20, 2018
Update Sept. 29, 2018: The National Oceanic and Atmospheric Administration has released new rainfall statistics and adjusted rainfall frequencies in Texas and Houston.
Updated Oct. 29, 2018, with recent photo of completed massive erosion control project on Buffalo Bayou.
Over the past several years, in the wake of extreme floods, we have received numerous complaints about damaging “erosion control” projects on the banks of Buffalo Bayou – projects damaging not only to the natural functioning and ecosystem of the bayou but also potentially to people living and working up and downstream of the projects.
Property owners bulldoze the banks, build massive retaining walls made of concrete block or sheet metal, dump piles of concrete construction debris into the bayou, strip and line the banks with concrete riprap.
This in addition to stripping the banks of trees and vegetation, reshaping the banks, gouging out pathways, and landscaping with walkways and non-native flower gardens.
Do they have the right to do this? Is it a good idea? Who owns the bayou really? What permits are required, if any, to do these things?
And does the bayou itself have rights?
Did Retaining Wall Make Flooding Worse?
What happens if someone installs concrete riprap or a massive retaining wall that deflects the flow of the bayou away from their property and floods neighbors or damages public park property? This has happened repeatedly on Buffalo Bayou.
In one case, a large property owner in River Oaks, whose bank is likely affected by a large stormwater outfall directly across the way, installed a controversial concrete block wall along several hundred feet of bank in 2016, initially without a permit from the City of Houston. That armoring washed away during Harvey, and the property owner has now rebuilt the eroded bank, apparently dumping material into the channel, and installed a massive sheet metal wall that has alarmed residents across the bayou and elsewhere, threatening a narrow strip of land that the Houston Parks Board has been eyeing for a hike-and-bike trail.
Is that legal? Is it right? Does it work?
Shocker: The Port of Houston Owns Buffalo Bayou
This will come as a surprise to many people: The Port of Houston owns the submerged lands of Buffalo Bayou all the way from the bay to the headwaters. In 1927 the Texas State Legislature gave the Port of Houston “all the submerged lands lying and being situated under the waters of Buffalo Bayou, San Jacinto River, White Oak Bayou, Bray’s Bayou, Simms Bayou [sic], Vinces Bayou [sic], Hunting Bayou, Greens Bayou, Carpenters Bayou, Old River, Lost River, Goose Creek and Cedar Bayou, and all other streams within the authority tributary to the Houston Ship Channel, so far up said streams as the State may own same … for public purposes and for the development of commerce only …” (See Sec. 5007.004)
Many people with property on Buffalo Bayou would think they own to the center line of the channel since the Harris County Appraisal District describes it that way and taxes it too.
Is the water in Galveston Bay really that clean?
Bay’s ‘A’ grade on water quality misleading, clean water advocates say
By Alex Stuckey, Houston Chronicle, Sept. 7, 2018
“I think it’s kind of misleading to label water quality an ‘A,’ ” said Brian Zabcik, clean water advocate for Environment Texas, after reviewing the [Galveston Bay] report. “But it’s a very narrow definition of water quality.”
So narrow, in fact, that Erin Kinney, a [Houston Advanced Research Center] research scientist, said researchers didn’t take into account any chemical spills in the water.
The levels of dissolved oxygen and nitrogen in water samples from rivers, bayous and the bay “were most often at acceptable levels for supporting diverse and healthy aquatic life,” the report stated. “The water quality problems that did exist — relating to high levels of phosphorus — typically occur in bayous that receive runoff and wastewater from human activity in residential, industrial, commercial, and agricultural areas.”
Public Comment Invited on Spending Plans for Harvey Aid
Plans, Priorities for City, County to Spend Federal Housing and Urban Development Funds
By Mike Morris, Houston Chronicle, Sept. 10, 2018
Houston area residents are inching closer to getting long-awaited Hurricane Harvey aid, and have until Oct. 6 to comment on the city of Houston and Harris County’s draft plans outlining how the governments will spend the more than $1 billion each soon will receive.
You can find the plans at this link.
In a mid-May memo to city council members, Houston’s Housing Director Tom McCasland expected the Department of Housing and Urban Development aid to be arriving in early September. Local officials now are hoping to launch their housing repair programs sometime in November.
