Abstract:

Water backpumped into Conservation Areas 1 and 3 is confined largely to canals and peripheral marshes. Water pumped into Area 2 extends into the interior marshes. Water that is backpumped into all three areas can alter water quality in the canals by breaking up water stratification, by resuspending bottom sediments, and by introducing water of a different chemical character. Concentrations of nitrogen and phosphorus decrease as water moves through the conservation areas in canals. This decrease is due partly to dilution by rainfall and runoff, and partly to net uptake in the canals and peripheral marsh. Uptake, estimated for three canals, accounted for a 2-percent decrease in phosphorus per mile and a 4-percent decrease in nitrogen per mile.
