OUR WATER: 87 billion gallons impounded, more to come

Oak Creek 109% full, Spence captures 30.5 billion

SAN ANGELO, TX - As of 7:00 p.m. Saturday night, October 13, 2018, the reservoirs of the Concho Valley have collectively impounded over 87 billion gallons of water, with much to come as rains continue through the week.

As impressive a number as that may sound, it is less than 20% of the total capacity of the water that could possibly be stored. Together the reservoirs can hold 462 billion gallons of the wet resource at maximum capacity, a total of 1.4 million acre-feet of water.

(An acre-foot of water is the amount of water needed to cover one acre of land one foot deep in water, or 325,851 gallons)
