Freshwater Diversion Sample Clauses

Freshwater Diversion. Diversion structures provide a controlled flow of freshwater and nutrients from the Mississippi River into a target area in Barataria Basin. The essential goals of freshwater diversions were to manage the productivity of wildlife and fishery resources by controlling salinity and to maintain xxxxx elevation by introducing additional freshwater and sediments to the xxxxx (Xxxxxxx et al., 1992). Two freshwater diversions, Xxxxx and West Pointe à la Hache (Figure 1-2), currently were opened along the Mississippi River in 1992. The Xxxxx project area contains approximately 13,000 acres (5,261 ha) of intermediate and brackish xxxxx. The West Pointe à la Hache project area contains approximately 9,300 acres (3,764 ha) of open-water and 7,600 acres (3,076 ha) of brackish xxxxx. Both diversions have a maximum design-pumping rate of 60 m3 s-1. Another diversion site, Davis Pond, was recently opened in April, 2002 with a maximum design-pumping rate of 300 m3 s −1 of freshwater to preserve about 33,000 acres (13,354 ha) of xxxxx and benefiting 777,000 acres (31,444 ha) of marshes and bays (Xxxxxxx, 1998). The $119.6 million project, the world’s largest freshwater diversion project, reintroduce fresh water, nutrients and sediment to the salt-threatened Barataria estuary, which stretches south to the Gulf of Mexico. Most of the diversion is expected to occur during the river’s high-water season in the first half of the year. But the structure will be closed when storms and tides are expected to increase stages in Lakes Cataouatche and Salvador.
