LCRA does not plan to lower Inks Lake, Lake LBJ, Lake Marble Falls or Lake Austin at this time. However, final decisions about lake lowerings are not usually made until November or December. Lake lowerings typically last up to six weeks, and generally are scheduled from early January through mid-February. Please monitor www.lcra.org or check back for any updates later in the year.
In order to preserve the water supply, LCRA - with permission from the state - cut off Highland Lakes water to most interruptible water customers in 2012, 2013, 2014 and 2015.
Water supply operations are conducted consistent with all applicable water rights and agreements. During water supply operations, needs for water are first met with the natural flow of the Colorado River - to the extent allowable - to reduce the amount of water used from the Highland Lakes. Water may also be released from any of the Highland Lakes as needed to manage excess flood waters.
Releases from Lake Austin are made when needed to meet downstream customer needs, and to supplement the natural flow of the lower river when needed to meet environmental flow requirements. Customers that take water from the Colorado River downstream of Lake Austin include Fayette Power Project, industrial customers in Matagorda County, the City of Pflugerville, Decker Creek Power Station, Lost Pines Power Park and others. Environmental flow requirements include TCEQ requirements to maintain instream flows along the lower Colorado River and supply freshwater inflows to Matagorda Bay and estuary.
Releases from Lake Travis are made when needed to replace water that is released from Lake Austin, and to supply water to customers along Lake Austin. Customers that take water from Lake Austin include the City of Austin, West Travis County Public Utility Agency and others.
Releases from Lake Buchanan are made when needed to replace a portion of the water that is taken or released from Lake Travis, and to supply water to customers along lakes Inks, LBJ, and Marble Falls. Customers that take water from the Highland Lakes above Mansfield Dam include the City of Austin, City of Cedar Park, Travis County WCID No. 17, City of Leander, Lakeway MUD, Ferguson Power Plant and others.
