Waterbody Improved

ia_circle Erosion from heavily grazed pasture lands and intensively farmed cropland caused excessive siltation in Iowa's Lake Icaria, triggering the Iowa Department of Natural Resources (IDNR) to place the lake on the state's 1998 303(d) list of impaired waters. The local Soil and Water Conservation District realized that the lake, which serves as both an important water supply and recreation area, was being slowly degraded. They began working with landowners in the upper reaches of the watershed to install agricultural best management practices (BMPs) that reduce soil erosion. Their efforts were successful—water quality improved, and IDNR removed Lake Icaria from Iowa's 2008 303(d) list of impaired waters for sediment.
