The Lake Report By: Blake Kellum, SJRA December 6, 2012As recent as December 4, 2012, Southeast Texas was categorized as having drought conditionsin the moderate or severe range. It seems that weather forecasters, across the state of Texas,are sending out confusing messages these days… I’ve heard everything from “expect droughtconditions to continue through spring” to “a return to normal winter rainfall amounts areexpected.” It seems to be a “coin toss” and nevertheless not much has changed for conditionson area reservoirs as of late.Lake Conroe’s level continues a slight downward trend and is currently reportedat 197.93above mean sea level (msl) by the San Jacinto River Authority. This is a bit over 3 feet belownormal pool elevation of 201.00 msl. SJRAhas received almost ½ of an inch of rainfall at thedam since the start of the month, but it has had little effect on lake level because of extremelydry soil conditions that act like a sponge to soak up any potential runoff. With both air andwater temperatures cooling and cloudy days, the evaporation levels are not affecting lake levelas severely as during the warm months.
Lake Livingston, with its massive 17,000 square mile drainage, continues to hold fairly steady atnear normal level at ¾ of a foot below. Reported stage, or elevation, at the dam is 130.26msl(normal is 131.00msl). Rainfall in the immediate water shed, since the first of the month, hasaveraged less than ½ of an inch, but as always, any heavy rainfall event in the upper watershedaround the Dallas/Fort Worth Metroplex can impact flows and lake level. The Trinity RiverAuthority is reporting a discharge rate of 1,000 cubic feet per second (cfs) at the dam. Theselow flows are continued to satisfy the needs of TRA’s downstream customers and stakeholders.For more information on reservoir conditions and much more, go to:www.sjra.net for Lake Conroe and San Jacinto River Authority informationorwww.trinityra.org for Lake Livingston and Trinity River Authority information.For information on Lake Levels in all 50 states go to www.lakelevels.info and select the state ofyour choice from the menu.
