This spring, sparsely populated Emmett County will begin a large upgrade to the Tuttle Lake watershed, the Estherville Daily News reports.

Two wetlands will help filter runoff from a total of 3,212 acres. In the past, phosphorus, nitrogen and sediments in runoff cause algae and turbidity problems in the lake.

Because of those problems, the EPA placed Tuttle Lake on its Impaired Waters List in 2002.
