Gajeske's Pumps Return for 2014


For the third year in a row the City of San Angelo will pump water from Twin Buttes' South Pool into the Equalization Channel.  The setup is a virtual repeat from 2012 and 2013.


As of now there are no intake pipes leading into the water.


I'll post more pictures later.

Pumps Are Back at South Pool


San Angelo Live picked up the City's rumored intent to pump the South Pool for the third year in a row.  City Council approved pumping in their April 1 consent agenda.  There was no discussion on the item.

I visited the South Pool today for recreation purposes, accessing the lake from a different entrance than San Angelo Live. The lake is up slightly to 1921.25 feet elevation.  The City's bid documents state they plan to pump ten feet out of the South Pool (down to elevation 1911 feet).  I don't think that's physically possible given the size of the pipes.  They might could get there with a straw.

Today I saw three pumps, along with three diesel tanks.  They're back in the spot they occupied the last two years (see picture from 2012 above). The scene today was distinctly more brown.

With no intake pipes going to the water another windsurfer and I were able to drive down the beach past the Equalization Channel to access the west wind.  I expect shoreline access to be reduced dramatically in the near future.

The wind blew today but it was highly variable, typical of our west winds.  I switched back and forth between a 110 liter and an 87 liter short board.  My sail size was 5.5 square meters, rigged flat, but it could've been 4.5 or 6.5, depending on the wind speed.

They weren't the roughest conditions I've windsurfed, but at times they were challenging.  I was glad to have someone else on the water today.  Age and the extra ballast I'm carrying made sailing a little tougher.  Can't do anything about the age but I can address the weight issue.  I'll do my darnedest to windsurf it off!

South Pool Sailable for Now


No pumps yet at the South Pool.  The water level keeps rising slightly.  I windsurfed  the South Pool today.  I rode a F2 130 liter shortboard and a 6.0 square meter North sail.  It was the right rig in the gusts.  I had a few runs that were about the fastest I've traversed the lake (parallel to the north shore).  Fortunately, I had company on the water. 

A convertible wetsuit and a pair of old Okespor booties kept me comfortable.  Despite our colder than normal winter our shallow lake is turning warmer quickly.

There are a few skinny, thorny mesquites growing in the shallow water.  There's the usual broken glass, familiar to anyone who recreates at either the North or South Pool at Twin Buttes. 

Waterfowl were out in force and I saw many fish jumping.  It was a great day to be outside and on the water.  It's not clear which method the city plans to use to pump the South Pool.  It'll either be the last two year's setup, three pumps with piping to the Equalization Channel or one pipe with three pumps over the dam to the South Concho River bed. 

It's time to sail the South Pool, before the pumps reduce it again to a shallow mud hole.

Water Advisory Board Meets Infrequently


Former City Councilman Paul Alexander spoke during public comment at San Angelo's City Council meeting on April 1st.  He shared his longtime interest in water and his desire to impact local water supplies while on City Council.  He parlayed that into an appointment on the city's Water Advisory Board.

The Water Advisory Board is yet to meet since Alexander's appointment.  I searched the city's old website numerous times on the Water Advisory Board only to find it rarely met. The purpose the few times it met seemed to be to rubber stamp a decision by former Water Chief Will Wilde.  One of those was the selection of Carollo Engineering for the Hickory Project.

The board met once under new Water Chief Ricky Dickson to approve the bid for the well field expansion.  That was July 29, 2013.

The city's new website shows no agendas under the Water Advisory Board archive.

The new website is disadvantaged as older documents must be manually loaded. 

The web has an article from 2003 and a brackish water use study from 2008.  Jim Turner at ConchoInfo raised Alexander's question a year ago.  Several weeks after his piece the Water Advisory Board met.

Piecing together the recent picture reveals the Water Advisory Board met in:

July 2013
August 2012
January 2011

The city's YouTube site has a video from 2013 where UCRA consultant Stephen Brown predicted fall rains, such that Dickson would need a boat.  Unfortunately, that didn't happen.

Oddly UCRA's Stephen Brown said they had something to bring back to the Water Advisory Board in a few weeks or a few months.  That didn't happen either.  The UCRA presented the Red Arroyo Project to City Council, not the Water Advisory Board.

The board with San Angelo's most important charge should be more than an annual rubber stamp.

Pumps to Return to South Pool


Tuesday, April 1st is deja vu time as San Angelo's City Council considers reinstalling Gajeske's pump system to move water from the South Pool at Twin Buttes Reservoir.  The city can pump to the North Pool via the equalization channel or over the dam to the old South Concho River bed which leads directly to Lake Nasworthy.  The three pumps can move 75 acre feet a day with gravity flow through the EQ channel, but only 25 acre feet a day if they go over the dam.

The city council background packet implies the pumping would go South Pool to North, taking only one month to move the South Pool's about 2,700 acre feet (current roughly 2,900 acre feet less the 200 acre feet that pumps can't get).  Then the pumps would be moved to the North Pool to pump that body, currently at about 1,900 acre feet ( and not pumpable using the city's last pumping arrangement).

Dead storage for the North Pool is elevation 1885 feet.  It currently sits at 1882.4 feet. 

This makes moving the water through the Equalization Channel a two stage pumping operation.  Stage one they've done several times, thus city officials have some idea as to the potential impact.  Due to seepage and evaporation losses the combined pools would be about 3,900 acre feet (that's without runoff rains).

The city successfully pumped the North Pool down to 1882 foot elevation, but not lower. After draining the South Pool it will be interesting to see where the City locates the intake piping to tap the remaining water  in the North Pool. They may need a lot of piping.

Of the current 4,900 acre feet, the city will be lucky to get 2,000 acre feet for its municipal water supply when all is said and done.  Lord knows, we need it and more.

Update 3-31-14:  Myself and another windsurfer had fun at the South Pool yesterday.  I was on a 4.5 square meter sail and a 110 liter board.  It was great in the gusts and a bit of work in the lulls.  I was worried about the water temperature, but was find with a warm shirt and convertible wetsuit.  The water was up slightly at 1921.25 feet elevation.   The next month and a half may be prime sailing time, i.e. pre-pumping.

City's Twin Buttes Water Rights Under Legal Challenge


Law360 reported:

Houston (February 19, 2014, 4:32 PM ET) -- A conservation group asked the Texas Supreme Court Tuesday to invalidate the city of San Angelo’s municipal water permit, arguing that state regulators should have more closely scrutinized the impact the permit would have on the environment and downstream users.

In a petition for review filed with the high court, the Concho River Basin Water Conservancy Association said that the Texas Commission on Environmental Quality should not have approved an amendment of the city’s existing water permit without first determining whether the change would unduly strain water supplies or adversely affect the rights of other water rights holders.

“Without requiring the proper [analysis], the commission amended the city’s water rights, stripping away existing special conditions designed to protect other water rights and the on-stream environment,” the petition said.

Concho — a nonprofit group formed to protect water rights tied to a tributary of the Colorado River — says that TCEQ should have considered how amending the city’s permit would impact the basin and others who rely on the water source under the Texas Water Code and state administrative law.

Because the city was not required by TCEQ to satisfy the so-called “no injury rule,” the permit amendment was improperly approved, Concho says. The Seventh District Court of Appeals also erred when it misinterpreted the high court’s decision in City of Marshall v. City of Uncertain and held that the TCEQ only needed to consider the public welfare, groundwater effects and consistency with state water plans before amending the permit, according to Concho.

“This error amplifies the commission's error in failing to acknowledge that its witness only provided an unsubstantiated and conclusory expert opinion that there were no adverse impacts caused by [the permit amendment] and did not perform the required no injury analysis,” the petition said.

And Concho says that the TCEQ should have compared the city’s original permit conditions with those of the amendment to conduct the appropriate analysis under the no injury rule. Instead, TCEQ took the “novel” position that a comparison was unnecessary because the amendment only operated to delete an outdated provision authorizing the city to store and release storm water, according to Concho.

TCEQ successfully argued to the lower appeals court that the state’s Water Rights Adjudication Act eliminated the distinction between “storm and flood flow” and “normal flow” of a river and that the city’s water permit amendment did nothing more than clarify its existing rights.

But Concho says that there is no case law to support TCEQ’s argument and notes that the Water Code and TCEQ’s own regulations still refer to the difference between storm flow and normal flow.

“It is incorrect that the Adjudication Act ‘did away’ with the normal-flood flow distinction for all purposes,” the petition said. “The appeals court failed to reach this issue and petitioner requests the court to grant this petition to address this issue, which is critical to the water law jurisprudence of the state.”

Concho contested San Angelo’s permit when the amendment was up for debate at the TCEQ, and sued in state court after the agency found the permit amendment would result in no adverse impact on other water rights.

The dispute revolves around water rights the city secured dating back to a 1960 permit that allowed the city to construct the Twin Buttes dam and reservoir and several subsequent amendments to the permit governing the amount of water San Angelo could draw down.

An attorney for San Angelo declined to comment Wednesday.  San Angelo is represented by Jason T. Hill, Martin Rochelle, Tom C. Massey and Timothy L. Brown of Lloyd Gosselink Rochelle & Townsend PC.

Concho is represented by Glenn Jarvis of the Law Offices Of Glenn Jarvis and Mary K. Sahs of Sahs & Associates PC.

The case is Concho River Basin Water Conservancy Association v. Texas Commission on Environmental Quality et al., case number 14-0028, in the Texas Supreme Court.

Twin Buttes Pumping to Return


Vendors have until March 12 to submit bids for pumping water from Twin Buttes.  Bid documents request a pump system capable of moving water from both the North and South Pools. 

No matter which route the city uses pumped water will need to cross long stretches of dry land.  Once again they'll be huge losses to seepage, thirsty vegetation and evaporation.

An addendum to the bid proposal stated the City plans to pump the South Pool down to elevation 1911 feet above sea level.  I don't think the city got that low last year when they used Option 3 and all three Gajeske pumps sucked air. 



The proposal seeks short term rental proposals to pump Twin Buttes water, likely in time for the May boat races.  As of now only the South Pool has water to give.
