The Galveston Bay Estuary Program was established in 1989 to implement a comprehensive conservation plan for Galveston Bay. Established by the federal government and administered by the Texas Commission on Environmental Quality (TCEQ), the program’s goal is to “preserve Galveston Bay for generations to come.” It is one of two estuary programs in Texas and one of 28 programs nationwide protecting estuaries “of national significance.”
An estuary is “a partially enclosed, coastal water body where freshwater from rivers and streams mixes with salt water from the ocean. Estuaries, and their surrounding lands, are places of transition from land to sea. … Estuarine environments are among the most productive on earth.”
As the Environmental Protection Agency points out, “what happens on the land affects the quality of the water and health of the organisms that live in an estuary. … For example, if a river or stream … passes urbanized and suburbanized areas, it gathers substances such as:
- fertilizers or pet waste that wash off lawns;
- untreated sewage from failing septic tanks;
- wastewater discharges from industrial facilities;
- sediment from construction sites; and
- runoff from impervious surfaces like parking lots.”
Buffalo Bayou is the main river flowing through the center of Houston and emptying into Galveston Bay. Numerous other creeks and tributaries, including Brays, White Oak, and Sims bayous, flow into Buffalo Bayou, which becomes the Houston Ship Channel.
Updating the Galveston Bay Protection Plan
The 22-year-old Galveston Bay management plan is being revised. The Houston Sierra Club is urging the general public to attend a Wednesday afternoon workshop in La Marque to “provide input on how we can have a cleaner and more ecologically intact Galveston Bay.”
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.
Dammed If They Do, Dammed If They Don’t
The Conundrum of the Buffalo Bayou Dams
Why so much water for so long in Buffalo Bayou?
May 26, 2016
The water in the normally empty reservoir had dropped only a few feet by the time we stood on the earthen dam looking down at the dark, opaque blue-gray surface. After almost a month, the rippling water below was still some twenty-three feet deep, and extended as far as we could see along the thirteen-mile long dam and far into the thousands of acres of flooded woods.
It had taken only a little more than twenty-four hours for the rains that began on April 18 to fill the vast flood control reservoirs in west Houston with a record amount of water: a total of more than 206,000 acre feet, a massive amount of water. Imagine 206,000 acres covered in a foot of water. Enough to cover more than eight times the acreage of both reservoirs to a depth of one foot. That much water would take an estimated four weeks to drain, according to reports at the time.
But that was only if there was no more rain. There was more rain, and it was taking much longer. The reservoirs, vast wooded parks with recreational facilities and nature paths, are still draining. As of May 24, the combined total of the two reservoirs was still about 90,000 acre-feet, down to a little less than half.
And Buffalo Bayou was still flowing high and fast, higher and faster for longer than ever before. Property owners upstream had flooded and property owners downstream who had hoped for more moderate flows were instead seeing long-standing trees falling into the fast-flowing stream, banks eroding, sediment collecting, debris causing water to back up onto their property.
Why was this happening and is there a way out of it?
Protecting Galveston, Houston, and the Texas Coast
Public Comment Needed By May 9
April 11, 2016
You may have heard about proposals to protect development along Galveston Bay, the Houston Ship Channel, and Houston itself from a giant storm surge. Dubbed the Ike Dike after Hurricane Ike in 2008, one leading plan is to build a 17-foot high levee for 50 miles along Galveston Island and Bolivar Peninsula, with a massive floodgate across the Houston Ship Channel.
Buffalo Bayou Runs Through It
But the Ike Dike is only one of several ideas being considered for the Houston-Galveston region by the US Army Corps of Engineers and the State of Texas. And in fact, in light of sea level rise (and due to subsidence, sea level is rising more rapidly on the upper Texas coast) and the potential flood damage from future storms, the Corps has been studying the entire Texas coast and gathering information for the past several years. In August 2014, the Corps issued a report called the Coastal Texas Protection and Restoration Project and held a series of four public workshops. And in May 2015 the Corps issued a Coastal Texas Protection and Restoration Study Final Reconnaissance 905 (b) Report.
A Notice of Intent to prepare a Draft Integrated Feasibility Report and Environmental Impact Statement for a Coastal Texas Protection and Restoration Feasibility Study, dated March 23, 2016, was published on the Corps’ Galveston District website. And on March 31 the Corps published a notice in the Federal Register calling for public comment on a draft Environmental Impact Statement for a Coastal Texas Protection and Restoration Feasibility Study. The public has only until May 9 to comment.
