Reasons cited included pollution from feedlots and farm fields, storm-water runoff in cities and towns, and increasing development around lakes. Some of the lake communities here are feeling development pressures, for example in Otter Tail and Douglas counties. With some lakes completely ringed with houses, cabins and resorts, development spreads to nearby areas. Though away from shoreline, this development still is in the watersheds which drain to the lakes, sending more runoff into them from roofs, streets and parking lots. Along with this expansion comes more wastewater needing treatment.
Septic systems can have a direct impact on lakes too.
Some communities are dealing with this by installing sewers around lakes, or using cluster septic systems, which treat wastewater from groups of homes and businesses. It will take vigorous partnerships among local and state governments, and on the part of all area residents, to maintain the natural beauty and rich resources that draw tourists and residents here.
