No Changes in Operation of Buffalo Bayou Dams
Release Rates May Be Looked At in Future
March 13, 2016
It was a dark and stormy night. Thunder boomed and heavy rain pelted the roof as a small group of us sat nervously in the middle of the rising Addicks Reservoir in far west Houston listening to the district commander of the Army Corps of Engineers tell us Addicks and Barker dams are safe.
Flanking Col. Richard Pannell last Wednesday, March 9, was a panel of officials from the Corps’ Galveston District office, as well as representatives from the Harris County Flood Control District and Granite Construction, the company awarded the $71.9 million contract to replace the leaky conduits in the 70-year-old earthen dams. The audience was a small crowd of about thirty hardy citizens who had braved the heavy traffic and heavy rain and managed to find the Bear Creek Community Center in the middle of a dark, wet forest despite the wrong address in the Corps’ public notice.
Col. Pannell made a thorough and convincing presentation of the history of the dams, the current problems, and what is being done about them. Among other work, the conduits in the two dams will be entirely replaced by new conduits in separate locations. This process will take about three years. He emphasized that the dams were in no immediate danger of failing and explained that the dams are labeled “extremely high risk” because of the potential consequences to Houston, the nation’s fourth most populous city, in the unlikely event that the dams failed.
Dams Operating Normally Despite Leaks
There were several questions about the capacity of the dams and the impact of repairs on the rate of future releases of water impounded behind the dams. The pattern of extended high releases and rapid drops has been criticized for damaging property on the bayou and killing trees and vegetation that control erosion.
After the enormous Memorial Day storm last year, the Corps began releasing impounded stormwater at 3000 cubic feet per second (cfs) for the first time. Normally the release rate is limited to 2000 cfs as measured by the Piney Point gauge. The Corps does not release water from the dams during a rain event, and the high releases began on June 1 and continued for ten days, finally dropping on June 12. The banks were already saturated from the storm, and the damage from the extended high flow was plainly visible up and down the bayou.

The TIRZ, Parks, and the Texas Constitution
Feb. 27, 2015
Here’s the report from the Feb. 25, 2015, Uptown TIRZ 16 board meeting about when the once-a-boat launch on Buffalo Bayou in Memorial Park at Woodway might be reopened.
Please note that Texas constitution guarantees the right of the people to access navigable waterways through public land.
The fenced-off Parks and Wildlife Paddling Trail takeout, referred to by the TIRZ as the “Woodway outfall,” is in need of a guardrail above a steep drop-off, parking reserved for the handicapped, and a gate that allows the park area to be closed at night, according to Sarah Newbery, the TIRZ 16 project director for Memorial Park.
The bayou access point on public land west of Loop 610 has been surrounded by a locked, curtained fence and closed to the public without explanation for almost a year since construction and landscaping were completed on the $1.36 million “erosion control” and drainage improvement project. The larger park area, known as the Old Archery Range, has been closed without explanation for nearly a decade.
The Houston Parks and Recreation Department is reviewing plans for the guardrail, parking, and permanent access gate for the former boat launch, Newbery told the board members meeting on the seventeenth floor of 1980 Post Oak in the Galleria. The TIRZ expects to send the plans out to bids in April and to finish construction by August, Newbery reported.
There will be a sign on the site by next week explaining all this to the public, said Newbery.
But why should the public not have access to the bayou through the park now, since there appears to be no legal or even safety reason why this part of the park should not be open in the meantime? The parks department could erect a temporary guardrail above any drop-off it deems dangerous, as it has done in Buffalo Bayou Park. There’s already a gate and a parking lot.
Will the New Memorial Park Master Plan Be for the People?
Nov. 5, 2014
Public Meeting Monday, Nov. 10, 2014, on proposals for a new Memorial Park Master Plan.

The Memorial Park Conservancy, Houston Parks and Recreation Department, and the Uptown Houston TIRZ are holding the second of four community meetings Monday, Nov. 10, 2014, about proposals for a new $1.8 million Memorial Park Master Plan.
The meeting will be from 6:30 to 8:30 p.m. in the White Oak Conference Center, 7603 Antoine Drive, 77004.
Go and ask them why they have locked up an entire forested section of our Memorial Park south of Woodway west of 610 and closed off access from there to Buffalo Bayou, access that historically had always been open to the public.
As far as we know, which is not much, the proposals for the new master plan make no mention of Buffalo Bayou. The previous master plan from 2004 recommended that the bayou be left alone as “a symbol of dynamic natural process.”
The 2004 plan reported that “a study of the Bayou’s dynamics and stability concluded that, after adjusting to increased urban runoff and water management structures upstream, the Bayou is vertically and horizontally stable, i.e., it is not deepening its channel nor is it dramatically widening its path.”
The landscape architecture firm of Nelson Byrd Woltz is leading the development of the new master plan. The City of Houston and the Uptown TIRZ plan to spend $100 to $150 million in tax money on capital improvements to the park in the next twenty years. None of that money is for park maintenance.
The Lovely Hidden Pool in the Secret Memorial Park Closed to the Public
Why Is the City Shutting Off Access to Buffalo Bayou in Memorial Park?

We were exploring in the woods yesterday (Saturday, Nov. 1, 2014) behind the “prison-grade” apparently permanent fence now surrounding the mysteriously closed $1.3 million not-a-canoe launch, “erosion control” project and drainage outfall in Memorial Park just south of Woodway. This is the park area just west of Loop 610 that used to be called the Archery Range because it was in fact used as an archery range from the 1950s until about 1988.
The bayou here was the site of an old sandstone ford near the current Woodway Bridge that was known in the nineteenth century as Dutchman’s Crossing, and the woods contain the remnants of a large brick kiln (and bricks), charcoal manufacturing, and antebellum market garden, orchard, and plant nursery dating from about 1838 to the 1930s, according to landscape architect and historian Janet Wagner.
We were looking for the much newer paved pathway that until recently led to the bayou from Woodway and that only a few years ago was used by the sporting public to haul and unload their canoes and kayaks on the banks of the bayou underneath the 610 bridge.
For some reason the entire wooded area has been fenced off and the public pathway we were looking for has been eradicated. Only a few pieces of concrete remain, lost under the overgrowth.
