Tracking Wildlife on the Bayou

Boys Scouting Part III

September 20, 2016

Boy Scout Paul Hung rallied his troop for the third floating inventory of the banks of Buffalo Bayou on a recent Saturday morning. Hung is documenting the tracks of wildlife as an Eagle Scout service project, and his fellow scouts in Sam Houston Council Troop 55 are helping.

Hung and other scouts have so far found over 130 tracks of animals including raccoon, beaver, possum, coyote, grey fox, bobcat, great blue heron, egret, otter, nutria, wild boar, and others. The tracks are being plotted on a map, and the information will be published as a pamphlet with the help of Save Buffalo Bayou, which is the beneficiary of the project.

Anyone who wishes to donate to help Paul Hung publish his Buffalo Bayou wildlife pamphlet can do so here.

About a dozen Boy Scouts and adult observers gathered with their Boy Scout wooden canoes at the Memorial Park boat launch at Woodway Sept. 10. It was a steamy morning, and they planned to paddle past Memorial Park and the Hogg Bird Sanctuary all the way to Lost Lake in Buffalo Bayou Park. Hung handed out clipboards and gave instructions for identifying and photographing the tracks and recording their location using a compass app on a cell phone. Nearby was the wooden box, built and recently installed by Troop 55 Boy Scout Saswat Pati, containing reusable bags for picking up trash on the bayou.

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.

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.

Note also the rerouting of the channel. Memorial Park and the Hogg Bird Sanctuary, including a tributary, are on the north, with houses in between. The entire south bank is River Oaks Country Club golf course.

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.

Cottonwood Down

A Giant Falls

June 14, 2016

We have been watching this magnificent cottonwood on the south bank of Buffalo Bayou in Buffalo Bayou Park. Beginning in 2012 the Harris County Flood Control District realigned the banks and removed a lot of trees and stabilizing vegetation from the banks of the bayou between Sabine and Shepherd streets for its “natural stable channel design” improvements in the park.

Those “channel conveyance” alterations left many of the few remaining large trees on the weakened banks in a vulnerable state. In the Fall of 2015 part of this grand old tree broke apart.

And now, finally, sadly, the great tree has fallen. Others will go eventually.

Big trees fall into the bayou all the time. It’s part of the natural process, and fallen trees collect sediment for bank building, provide fish and wildlife habitat, and slow storm waters. But trees, whose massive roots help hold the bank together, are not supposed to fall in the water because in the name of progress we dug up and destroyed the structure of the surrounding banks, breaking up the intricate root systems of the vegetation that had been there for a very long time.

Still, we have had unusually high rainfall and stream flow in our bayous. The banks in many places are now lush with new green growth and wildflowers. For nearly two months we have had record high flows in Buffalo Bayou as the Army Corps of Engineers attempts to empty the flood control reservoirs behind Barker and Addicks dams in western Harris County. We have reports of trees downed all along the bayou.

Watch this slideshow of the great cottonwood as it maintained its lonely vigil until the end.

Then And Now

The View From the Bridge

June 13, 2016

Okay, it was a trick question. We asked our readers to identify the location of Geoff Winningham’s lovely black-and-white photo of Buffalo Bayou taken in 1998. And we asked for a photo of the same view now.

Shoulda been easy. The photo was published in Winningham’s beautiful photographic study of the bayou, Along Forgotten River, which traces our Mother Bayou from its source in the Katy Prairie to its end in Galveston Bay. And the photo was identified, of course.

Except that somehow the identification in the book was wrong, says Winningham. He went out and checked himself last week. The photo was taken looking upstream from the Waugh Bridge, not the Montrose Bridge. Still, the view doesn’t look much the same. The river seems to bend differently now, after the “channel conveyance improvements” by the Harris County Flood Control District starting in 2010. Not so many trees either. Here’s the way it looks now. Still lovely.

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.

Paving, Flooding, and Loss of Wetlands: Making It Easier to Build More Roads

Public Comment Needed by May 7

May 3, 2016

The Texas Department of Transportation wants to make it easier to build roads over our vital prairie wetlands by creating a one-size fits-all statewide stormwater discharge permit. The Texas Commission on Environmental Quality (TCEQ) is considering the 53-page proposal, known as Permit No. WQ0005011000.

The new permit is opposed by wetlands activists such as Galveston Baykeeper, which would like to see the state Department of Transportation do a better job of protecting wetlands and enforcing federal law.

Highways and paved surfaces are a major source of flooding as they rapidly collect and funnel rainwater that can no longer soak into the ground. Wetlands detain, absorb, and cleanse stormwater, which is why they are protected under the federal Clean Water Act – if they have a connection to a federally protected waterway.

Coastal Prairie Different from Edwards Aquifer

Environmental attorney and Galveston Baykeeper board member Jen Powis says the organization has been watching the state transportation department move toward “one big statewide permit” for about two years. Until now permits were issued based on the specific conditions of each community, Powis told writer Janice Van Dyke Walden in the May/June 2016 issue of Gulf Coast Mariner magazine.

“I’m a strong proponent of local solutions for specific places,” says Powis. “We all know that Houston looks very different from the Edwards Aquifer.”

You can read the proposed Permit No. WQ0005011000 here. And here is how to make a comment about it to the TCEQ. Comments are due by May 7.

Out on the Bayou with the Boy Scouts

Documenting Wildlife Tracks and Weird Nature Stuff

April 6, 2016

We went out with Paul Hung and his band of intrepid Boy Scouts last week to document wildlife tracks on the banks of Buffalo Bayou.

We saw a lot of interesting things, including footprints of mysterious creatures behaving in puzzling ways, some strange yellow liquid, and flying seat cushions nesting in the trees.

This was the second outing for Paul and his teen-aged colleagues from Boy Scout Troop 55, Sam Houston Area Council. For his Eagle Scout Service Project, Paul proposed documenting the wildlife on the bayou as it flows along the southern edge of Memorial Park. Save Buffalo Bayou is the beneficiary, and we hope to publish Paul’s results as a pamphlet.

Fortunately the flow was very low, less than 200 cubic feet per second, which is about base flow in the bayou when it hasn’t been raining. The Army Corps of Engineers assured us in advance that the reservoirs in the dams upstream were empty, and barring any unforeseen weather event, the water would be low enough for us to see plenty of activity on the mud and sand of the banks. Which we did.

Paul was well organized. He handed out clipboards, small rulers, and post-it notes, and instructed his fellow scouts to use these with the GPS app on their cell phones to take photos and number and record the size of tracks. The group was divided into pairs in canoes. A few adults went along too, including Richard Hung, father of Paul, and Troop 55 Assistant Scoutmaster Janice Van Dyke Walden.

Tracks Everywhere

There were tracks everywhere. Creatures crawling, slithering, hopping and tiptoeing across the sand, burrowing, strolling, turning about and flying away; digging holes, chasing each other, stepping and sliding in and out of the water.

Reminder: The Threat is Still Alive

Operation Save Buffalo Bayou II

March 14, 2016

Okay, so we harshed the mood a little with our small, silent reminders that regatta contestants were paddling through a historic natural area still threatened with destruction.

“Thanks for polluting my day,” yelled one paddler in the crowd of hundreds of Buffalo Bayou boaters playing loud music and stopping to pee in the woods. We were watching from the sandy bank of the lovely middle meander, forested with young willows and box elder that would all be cut down, the meander filled, graded, and planted with grass.

The event was the 44th Annual Buffalo Bayou Regatta on Saturday, March 12. And once again we hung our beautiful Save Buffalo Bayou banner (Night Heron by Houston artist Frank X. Tolbert 2) from the railroad bridge and set out small white signs alerting participants to the fact that the wild stretch they were passing through would all be bulldozed under a plan proposed by the Harris County Flood Control District and the Bayou Preservation Association (BPA).

The project, known as the Memorial Park Demonstration Project, demonstrates exactly the wrong thing to do. (See Buffalo Bayou Park and Fonteno Park.) It would raze most of the trees and vegetation along more than 1.25 miles of the 18,000-year-old bayou as it passes by Memorial Park and the Hogg Bird Sanctuary. These trees and vegetation and even the sand are part of the riparian zone, essentially wetlands, that hold the banks together, cleanse and filter the water, slow and absorb storm runoff, provide wildlife habitat, among many other important ecological functions. The $6 million “natural channel design” project, financed with $4 million in county and city taxpayer funds, would dredge and reroute the bayou and plug tributaries, obliterate ancient cliffs, destroy 250,000-year-old sandstone formations, and fill in our lovely meander (a natural detention area). Killing the bayou’s ecosystem in the name of “restoration.” And landscape design.

And no, contrary to rumors, the project, although holding its breath, is not dead. The Army Corps of Engineers is still deciding whether to issue a permit for the project, which is otherwise a violation of the federal Clean Water Act.

The Bayou Preservation Association first formulated the plan for the project in private meetings in 2010 and  former BPA president Kevin Shanley, then a principal with the landscape architecture firm SWA Group, was the primary promoter. SWA Group is the design firm that is also responsible for the landscape design of Buffalo Bayou Park downstream east of Shepherd.

So this is why we had signs up warning of landscapers lurking. In Buffalo Bayou Park downstream, we set out a few signs pointing out that landscaping has washed away (several times actually) and that removal of vegetation has caused erosion problems, and that repairs were $$$$ (paid with City funds). Yes, we were bad! Those signs did not last long, however.

Upstream around Memorial Park and the Hogg Bird Sanctuary our signs pointed out where beavers live, where banks were being naturally rebuilt by the bayou, and the Pleistocene bluffs that would be graded into a slope. Interestingly, the bayou, during and after the Memorial Day flood in 2015, has already graded the lower banks of those steep bluffs into a slope.

The River Oaks Country Club is theoretically a one-third partner in the demonstration project and owns the entire south half of the project reach. But in the meantime the club in two places has armored its banks with ugly concrete riprap, one of the most environmentally destructive methods of erosion control (pdf), and also, we allege, in this case illegal, as we contend that much of the riprap was placed in public waters, also a violation of the Clean Water Act.

The club, unfortunately, is having erosion problems on its high banks in those places because it cut down a lot of trees and extended the mowed and watered grass of its golf course up to the edge of the banks.

We put out signs pointing out that riprap damages the ecosystem and is part of the problem, not the solution.

But we’re glad people had fun, enjoyed the bayou, and picked up some of trash.

Maybe they’ll think about the future of the bayou.

And special thanks to river guide Tom Helm and to Richard Hyde for extra long duty putting out and picking up our banner and picking up our signs.
