The goal of the Corps of Engineers Urban Study Program is to provide planning assistance to local interests in a variety of water resource areas. The St. Paul District conducted the Grand Forks-East Grand Forks GFEGF Urban Water Resources Study which was a cooperative effort among local, state and federal agencies. Primary attention was given to flood control, water supply and wastewater management supporting investigations addressed recreation and energy conservation. Flood control studies showed that the East Grand Forks levee project authorized in 1953, but not constructed, still was economically feasible and recommended further study under the Corps postauthorization program. Flood emergency plans were developed jointly with both cities to improve their flood fight preparedness and effectiveness. Regarding water supply, a low-flow study of drought flows on the Red and Red Lake Rivers found that river flow, plus storage provided by the cities low-head dams, would satisfy 2030 demands during a 50-year drought. The study concluded that separate wastewater treatment facilities based on lagoon systems were the most cost-effective means of handling major point sources through 2030. However, if zero discharge criteria were promulgated the large land areas needed for lagoon effluent disposal could make advance mechanical treatment attractive. Overflows from Grand Forks combined sewers into the Red River, which is the citys drinking water source, were the most serious problems.
