City to Pump Water from South Pool

San Angelo City Council agenda for April 3rd shows the following item:

Consideration of selecting Gajeske, Inc. for RFP WU-02-12 Lake Pumping System to transfer water from the South Pool of Twin Buttes Reservoir to the North Pool and authorizing the Interim City Manager or his designee to execute any necessary related documents.

I wrote about the City's RFP for pumping dead pools in late January. The South Pool increased several feet, while the North Pool withered.

This isn't the first time the subject of pumping from the South Pool arose.  Harken back to May 2004:

CONSIDERATION OF MATTERS DISCUSSED IN EXECUTIVE/CLOSED SESSION, SPECIFICALLY TO ADVISE ATTORNEY TIM BROWN OF QUESTIONS RAISED BY TCEQ AND TO BEGIN THE PREPARATION OF A RESPONSE

Council discussed whether to apprise Attorney Tim Brown of questions raised by the TCEQ regarding the City's rights to pump water from the south pool over Twin Buttes Dam and to divert water by City property leaseholders along the South Concho River.

Motion, to advise Attorney Tim Brown of questions raised by TCEQ and request that he begin the preparation of a response, was made by Councilmember Rainey and seconded by Mayor Lown. Motion carried unanimously.

Last summer the issue rose again

DISCUSSION AND CONSIDERATION OF PUMPING WATER FROM THE SOUTH POOL OF THE TWIN BUTTES RESERVOIR
City Manager Harold Dominguez and Water Utilities Director Will Wilde presented background information.  A copy of the lake level chart document is part of the permanent supplement file.  Discussion was held on the creating a plan to pump the water in the future from the pools and explore recreational uses for the area.
Note the South Concho River, which feeds the South Pool, has the most consistent flow of any river in the Concho Valley.  What recreational uses did Council have in mind for the South Pool?

Will the City of San Angelo deplete our most drought resistant windsurfing lake and turn it into a mudders' paradise?  Time will tell.

One thing's for sure, access will be limited, per Council actions in January 2012: 

Motion, to authorize staff to move forward with controlled vehicular access to the four designated access points, as presented by staff: 1) access to south shore of the north pool of Twin Buttes, 2) access to the west side of the south pool of Twin Buttes, 3) access to the east side of the south pool of Twin Buttes, and 4) access to the area north of Hwy 67 related to public safety issues and access to public areas at the Twin Buttes Reservoir, was made by Councilmember Hirschfeld and seconded by Councilmember Alexander. Motion carried unanimously.

Councilmember Alexander suggested staff consider opportunities to generate revenue, specifically user fees, and reinvestment strategies.

Twin Buttes stakeholders input was sought on February 16, long after the Council train had left the station.  I'm concerned given Twin Buttes stakeholders placed RV hookups low on the priority list, yet such amenities were high in the consultant's report.



User fees, this is starting to feel like a setup.  Will I be charged per board, maybe per sail?

Twin Buttes: Tale of Two Pools


The South Pool recently sent water into the Equalization Channel at Twin Buttes.  I wonder if the trickle reached the badly depleted North Pool (pictured above).

While 2012 rains greened the ground, they're yet to add substantial runoff to area lakes.

 
Twin Buttes is the blue line in the chart above.  It's back in the hurtin' zone, with most of the water in the South Pool and away from the dam gates.  Pray for a gully washer in the Twin Buttes watershed..
