The Arbuckle Reservoir is the first significant new water supply reservoir developed in the lower Colorado River basin in decades. LCRA built the reservoir off the main channel of the Colorado River, near Lane City in Wharton County.
The reservoir, which formerly was known as the Lane City Reservoir, could add up to 90,000 acre-feet of water to the region's supply. It 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 benefit the entire basin by helping reduce the amount of water otherwise required to be released from the Highland Lakes to serve downstream demands, including industrial and agricultural customers.

Status of Operational Testing as of May 2019: During the course of conducting operational readiness testing, LCRA has detected seepage from the subsurface in three areas outside the reservoir perimeter. Given the topography and soil characteristics of this area of Wharton County, such seepage is not considered extraordinary. Engineering analysis is currently being conducted to determine the nature and cause of the seepage and to develop a remedial action plan to resolve the situation. A temporary delay is necessary to ensure the long-term operation of the facility without any undue erosion impacts or damage to the reservoir. It is anticipated the reservoir will be fully operational in the spring of 2020; however, should the remedial work be completed earlier, the schedule for operationalizing the reservoir will be adjusted accordingly.
Prairie Regulating Reservoir Project
The proposed Prairie Regulating Reservoir Project would provide LCRA operational flexibility by helping meet the demands of downstream customers within the Lakeside Irrigation Division. The project proposes a gravity-fed, 2,000 acre-foot, off-channel reservoir and improvements to the existing collection and distribution system.
LCRA received an $8 million federal partnership award to help construct a regional conservation project to improve agricultural water management within the Lakeside Irrigation Division.

Bastrop groundwater wells
LCRA also added to the region's water supply by adding four groundwater wells in Lake Bastrop in Bastrop County. The project allows LCRA to pump up to 10,000 acre-feet of water a year, under certain conditions, to cool LCRA's Lost Pines Power Park in Bastrop County.
LCRA also owns the groundwater rights associated with the 5,000-acre Griffith League Boy Scout Ranch in Bastrop County, and is seeking permits to drill up to eight wells for the production of up to 25,000 acre-feet of water when the need arises to meet demand.
Additional water projects
LCRA is exploring additional water strategies for Central Texas, including using surface water, treated effluent and groundwater to address the needs of the high-growth areas of LCRA's water service area.
