Endocrine-disrupting contaminants such as environmental estrogens have been found and studied in large lakes and streams and shown to exist at concentrations that have adverse effects on wildlife. However, very little is known about the sources and effects of environmental estrogens in small, shallow lakes. Preliminary data suggests that these compounds are present in shallow lakes and have an effect on the survival and reproduction of wildlife. Researchers at the University of St.
Moose, one of Minnesota's prized wildlife species, are dying at much higher rates in Minnesota than elsewhere in North America. Recently observed increases in mortality rates amongst some moose in northeastern Minnesota have led to concern that the population there may be entering a decline like that seen in the northwestern part of the state, where moose populations fell from over 4,000 to fewer than 100 in less than 20 years. Additionally the specific causes of increased mortality amongst individual moose remain under investigation.
With only 1% of Minnesota’s native prairie remaining, many prairie plant and animal species have dramatically declined. Of the 12 butterfly species native to Minnesota prairies, two species, the Poweshiek skipperling and the Dakota skipper, have already largely disappeared from the state and are proposed for listing under the U.S. Endangered Species Act despite being historically among the most common prairie butterflies and having their historic ranges concentrated in Minnesota.

Pasture and hayland account for 62% of the agricultural land use in Clearwater County. In 2012, it was the 12th largest producer of beef cattle in Minnesota. In a county where 22% of pasture/hayland acres are within 300 feet of riparian areas, management practices need to be introduced that enhance rather than restrict the farm operations that use these zones for their livelihood. Clearwater County's Silver Creek and Ruffy Brook are currently listed as impaired by fecal coliform.
Improve parking, buildings and other features at the Lake Elmo Swim Pond to better meet ADA standards and improve other park visitor needs. The swim pond area was originally developed in 1986. The park had 464,200 visits in 2013.
Renovation and partial relocation of the roads and parking areas at the park; including improvements to buildings and other related facilities. The current park building was constructed in 1985. The park had 75,300 visits in 2013.
