The reservoir will be about twice the size of this reservoir in Florida.
The embankment of the new reservoir will be similar to this reservoir in Ohio. The sides will be about 40 feet tall.
The Lower River Colorado Authority is aggressively working to expand the region's water supply and meet the LCRA Board of Directors’ goal of adding 100,000 acre-feet per year to the region's water supply.
Lane City Reservoir Project
The largest of LCRA’s new water supply projects is an off-channel reservoir LCRA is building near the Texas Gulf Coast. The project will be the first significant new water supply reservoir developed in the lower Colorado River basin in decades. The Lane City Reservoir will be constructed off the main channel of the Colorado River, near Lane City in Wharton County.
The reservoir could add up to 90,000 acre-feet of firm water to the region's supply. Firm water is water that can be counted on without shortage even during a repeat of the worst drought conditions in the region's history.
The Highland Lakes were created to manage floods on the Colorado River and to provide a sustainable source of water for the basin as a whole. The Lane City Reservoir is the first project that will allow LCRA to capture and store significant amounts of water downstream of the Highland Lakes. The new reservoir will increase LCRA's operational flexibility, which will lessen the need to send Highland Lakes water down the Colorado River to customers near the coast, while improving water reliability and efficiency to meet agricultural and environmental demands.
The reservoir is expected to begin operating in 2018.

Bastrop groundwater project
The Bastrop County groundwater project has added 10,000 acre-feet to the water supply by allowing LCRA to pump up to 10,000 acre-feet of water a year, under certain conditions, at LCRA's Lost Pines Power Park in Bastrop County. Four wells have been drilled.
