Memorial Day Weekend Rains Bust Drought

In five days San Angelo made up a seven inch rainfall deficit.  Not only did preciptation surge into the "above average" category, runoff rains filled Lake Nasworthy and added huge amounts to area lakes. The Standard Times reported:

As of 10:45 p.m. Monday, the National Weather Service of San Angelo reported the city’s year-to-date rainfall at 7.82 inches as precipitation was still falling. Monday’s downpour put San Angelo above the rainfall average. The normal year-to-date total for this time of year is 7.47 inches, according to the National Weather Service.
Concho River flow in San Angelo provides a picture of the rainfall events from Thursday to Monday evening.

Pecan Creek's flow is also an indicator of the rains pulses received over the five day period.

The North Concho River feeds O.C. Fisher Lake.  It stands to get more water given increased flow upstream.  Here's the view from Sterling City and Carlsbad:

So far O.C. Fisher is up roughly seven feet.

Twin Buttes is up twelve feet and tributary flow indicates more is on the way.  The Middle Concho River, Dove and Spring Creeks feed Twin Buttes North Pool.


The North Pool is also fed by the South Concho River via the Equalization Channel.

These images indicate the North Pool's elevation should continue to rise.  Twelve feet and counting.

This more than barely breaks our drought.  Our abundant holiday rains are life giving and sustaining.  They are a blessing and I am grateful.
