WebAug 1, 2024 · The amounts of phosphorus downstream of the city have decreased about 77% from the highest levels in 1984 because of both voluntary and mandatory restrictions on phosphorus detergents in the city. As the bottom line shows, though, the total phosphorus load in the more agricultural area north of town continues to increase. WebBoth water quality and phytoplankton assemblages were sampled biweekly during the summers from 2001 to 2013. The concentrations of total phosphorus, soluble reactive phosphorus, and total nitrogen decreased 66%, 93% and 31%, respectively, in response to the hypolimnetic aeration and alum treatments since 2005.
