The Lower Colorado River Authority, which manages the Highland Lakes system in Central Texas, announced it would begin lowering Inks Lake for a period of eight weeks starting Oct. 1.

The lowering will cause Lake Travis, located downstream from Inks Lake, to rise by about 3.5 inches, according to a news release from the authority.

In a nutshell

The LCRA announced Sept. 9 that the lake would be lowered to provide property owners an opportunity to work on docks and boat slips, as well as to remove debris from the lake and shoreline.

Inks Lake will be lowered by 1 foot per day to about 879 feet above mean sea level by Oct. 9. It will then be slowly refilled by Nov. 28. Lowering the lake will require the release of about 5,000 acre-feet—about 1.6 million gallons—of water through the hydroelectric generator at Inks Dam.


Explained

The 5,000 acre-feet of water will flow downstream to Lakes LBJ and Marble Falls into Lake Travis, which will rise by about 3.5 inches. As of Sept. 10, Lake Travis was at 673.08 feet above mean sea level, about 87% full, per LCRA data.

Remember this?

Inks Lake was last lowered in 2020.
