Weekend rains welcome for Houston area lakes

Weekend rains bring more than just a drop in the bucket, but we're not out of the drought yet.

ABC13 Meteorologist Travis Herzog crunched some numbers from the US Geological Survey's lake sensors and determined the following:

  • Lake Houston:
    Over 1.7 BILLION gallons of water added (4 percent of the lake's total storage capacity)
    Lake capacity is now at its highest level since August 6th
  • Lake Conroe:
    Over 782 million gallons of water added (0.5 percent of the lake's total storage capacity)
    This brought the lake capacity to the level it had on Thursday. The storage is dropping fast as it is being drained to stabilize the level at Lake Houston.
  • Lake Livingston:
    Almost 7.5 BILLION gallons of water added (1.3 percent of the lake's total storage capacity)
    This brought the lake capacity to the level it had on Tuesday.

So it was more than a drop in the bucket, but we've got a long way to go. It's estimated that we'll need 18-24 inches of rain over a 30 day period to pull out of the drought. Yesterday we averaged 2-4", with 5-7" totals stretching from Pearland to Pasadena to Clear Lake, then down I-45 to Santa Fe.

The 3.02" of rain at Bush Airport was the most since July 2, 2010, when the remnants of Hurricane Alex flooded the city with 5.43" of rain. That was 464 days ago!
