TRWD has also constructed more than 250 miles of large diameter water pipelines (72” and larger), 27 miles of floodway levees built by the Army Corps of Engineers, more than 72 miles of Trinity River Trails and a 2,000-acre wetland water reuse project designed to increase future water supplies for the area. Benbrook Lake, an Army Corps of Engineers facility, is also part of the TRWD water supply system. Future supply options include reallocations in Army Corps reservoirs and new reservoirs that require federal permits administered by the Corps.

Katherine Zitsch – Vice President
Katherine Zitsch leads the Natural Resources Division at the Atlanta Regional Commission (ARC), the regional planning agency for Metropolitan Atlanta. She is also the Director of the Metropolitan North Georgia Water Planning District, which is responsible for water planning in the 15‐county Atlanta area. Together, these agencies work to meet the water supply needs of 5.7 million people in Metropolitan Atlanta. ARC acts as the contracting and coordinating agent for local governments, and as the representative for local governments on matters related to reservoir and water supply operations at two U.S. Army Corps of Engineers reservoirs—Lake Lanier and Allatoona Lake—which collectively provide approximately 80% of the region’s water supply. ARC believes an effective Corps made inflow/return flow policy and deference to States in allocating water are critical to maximizing the water supply benefits provided by federal reservoirs.

JPP reservoir is owned and operated by the U.S. Army Corps of Engineers and Murfreesboro has had a water supply contract with the Corps since 2003.

Glenn Page - Director 

Glenn Page represents the Cobb County‐Marietta Water Authority (CCMWA), from which he recently retired as General Manager.  CCMWA is a wholesale provider of drinking water to nearly 1 million people in 5 counties in northwest metropolitan Atlanta. CCMWA operates two drinking water treatment plants, one drawing from the Chattahoochee River downstream of Lake Lanier and the other receiving its water directly from Allatoona Lake through a 1963 water storage contract with the U.S. Army Corps of Engineers. CCMWA also owns and operates a pumped storage reservoir upstream of Allatoona Lake, permitted by the State of Georgia to release water as “made inflows” to CCMWA’s storage in Allatoona for CCMWA’s sole use. One of CCMWA’s customers operates two water reclamation facilities that produce return flows to Allatoona that are also allocated by the State of Georgia to CCMWA. Among other things, CCMWA is concerned about preserving state primacy in allocating waters of the state, and about the proper accounting of made inflows and return flows by the Corps in determining the amount of water available for water supply through CCMWA’s purchased storage.

George Otstott - Director

George Otstott is Vice President of the Board of Directors for the Northeast Texas Municipal Water District (NETMWD), based in Hughes Springs, TX.  After disastrous flooding in the Cypress River Valley in 1947 a dam to control flooding and provide a water supply to the river valley basin was built by USACE and formed the Lake O’ the Pines Reservoir just west of Jefferson, Texas.  The dam was built in partnership with seven local cities, including Jefferson, George's hometown, who acquired the rights to the water supply and later became the Northeast Texas Municipal Water District. NETMWD is a regional unit of government which was specially created in 1953 by the Texas Legislature to be the local sponsor of Lake O' the Pines Lake O' the Pines Reservoir. The district serves 8 counties in Northeast Texas and provides finished water to 10 cities in the basin and raw water to several cities and industries in the basin. NETMWD works with the USACE, state agencies of Texas, and additional stakeholders on water resources in northeast Texas, including Lake O' the Pines.  NETMWD administers water protection programs in the entirety of the Cypress Creek Basin.  NETMWD works to assure sustainable habitats for threatened or endangered species and helps to assure the vitality of wetlands that have been recognized by international treaty to have significance in the Cypress Creek Basin.
