The source of troublesome lake algae is not always clear, but an interdisciplinary research project with two Michigan State University researchers found an answer may include colder groundwater that feeds some inland lakes. This finding could help predict the formation of harmful algal blooms to mitigate their impact on drinking water, tourism, fishing and fish
Article Credit: wisconsinlakes.org Fertilizers, leaves, grass clippings, eroded soil, and animal waste are all sources of nutrients, including phosphorus. Phosphorus is main nutrient that drives eutrophication (premature aging) in most lakes. Relatively small amounts of phosphorus can cause water quality declines. A concentration of 25 parts per billion of phosphorus in water can promote excessive
In December, 2010 Wisconsin became the first state in the country to adopt phosphorus water quality standards for lakes, reservoirs, rivers, and streams. The Environmental Protection Agency has approved Wisconsin’s revised rule as a revision to Wisconsin’s federally-approved National Pollutant Discharge Elimination System program under the Clean Water Act. Under the new rules DNR determines
