Cage at North Pool Nearly Underwater

In 2013 the City of San Angelo had to pump water to the cage at Twin Buttes Reservoir's North Pool.  The picture below shows a dry lake bed in front of the structure.
That changed with Fall 2018's massive runoff.  The top of the cage can be seen below.  Look for the thin white horizontal rectangle slightly above the water's surface.  It's below the gatehouse at the top of the dam.

For decades the City's excuse for poorly maintaining Twin Buttes has been:  "There's no water."  That's changed dramatically.  We'll see if the city does any better now that Twin Buttes holds a huge inventory of untreated water to sell.  I'll check with city officials and post their response.

Happy New Year!

Twin Buttes Reservoir reached 1929.55 ft elevation today.  It's up over 36 feet from early September levels.  That's one mighty blessing!

Lucas Oil Bails Out of Drag Boat Races

Lucas Oil announced the cancellation of its drag boat racing series after a nine year run.  San Angelo hosted a drag boat race at Lake Nasworthy for over a decade   The race could continue outside Lucas Oil sponsorship.

Update 12-8-18:  City Council will discuss the boat race on 12-8-18 in Executive Session.

Update 12-28-18:  The City can consult Marble Falls which lost its 26 year drag boat race in 2018.

Twin Buttes Equalized

The North and South Pools at Twin Buttes Reservoir equalized this past week.  Concho Valley Homepage had it happening at 1926.5 feet elevation which occurred on October 28th.  

I thought it might happen at 1927 feet, a level I had seen the South Pool when it had some flow into the North Pool.   The twin pools hit 1927 feet at the stroke of midnight on Halloween. 

The lake is up another third of a foot since then and the two pools hold over 100,000 acre feet.  It's an absolute blessing.

Update for Water Advisory Board

I took the liberty of updating a water supply slide from last month's Water Advisory Board meeting.  We have been blessed with significant runoff rains.  For this I am grateful.

North and South Pools to Equalize with Less than Two Foot Rise

Image result for twin buttes north pool level with south pool

If the North Pool at Twin Buttes Reservoir increases 1.7 feet it will be level with the South Pool.  This hasn't happened in my 25 years living in San Angelo.  I've windsurfed and paddle-boarded both pools but never have been able to go between the pools (other than by land).

Our recent water level rise has been historic.  Early September 2018 pool levels were similar to those pictured here from 2012.  The North Pool is up over 32 feet since mid September.

The irony is the City of San Angelo just thumbed Tom Green County farmers who have significant water rights to Twin Buttes.  It will interesting to see if farmers chose to ignore city effluent in favor of Twin Buttes lake water.

Update 10-28-18:  The Standard Times ran a story on wastewater reuse.  It did not mention the city deal with local farmers to take effluent in place of water from Twin Buttes.

Update 10-29-18:  Concho Valley Homepage picked up the equalization story.   They said the pools equalized at 1926.50 ft elevation.  From prior readings of the South Pool the target I used was 1927 ft elevation.  What's a half foot between friends?

Massive Runoff into Twin Buttes and Lake Ivie

Twin Buttes North Pool rose over 14 feet, adding at least 30,000 acre feet to San Angelo's water supplies.

 The North Pool only has to increase 6 more feet for the pools to equalize.  That hasn't happened for a long time.

Lake Ivie did even better with a 48,000 acre foot increase.

Blessings from heaven.  Lord, keep everyone safe in the midst of all this.

Update 10-19-18:  Twin Buttes holds roughly 80,000 acre feet of water between the two pools.

Update 10-21-18:  It now holds over 90,000 acre feet between the two pools.  Lake Ivie has double this amount with 185,600 acre feet and Lake Spence 113,300 acre feet (with no functioning pipeline to supply the city water).
