Little Rock Lake (05-0013) Investigation and Recommendation for Inclusion on 2008 303(d) Draft List for Nutrient Impairment

Little Rock Lake experienced very severe algal blooms over the past few weeks in July and these blooms raised extensive concerns with lakeshore property owners and lake users. These concerns were forwarded to the Minnesota Pollution Control Agency (MPCA) and Minnesota Department of Natural Resources (MDNR). Multiple staff from the MPCA surveyed conditions on the lake during the week of July 23, 2007. This memorandum will focus primarily on sampling conducted by Harold Wiegner, David Tollefson (intern) and myself on July 25 but will also note an initial investigation by Matt Lindon and Kelly O'Hara on July 12, 2007.
