PUBLIC INPUT SOUGHT ON WATER QUALITY STANDARDS FOR LAKES USED FOR SWIMMING
A series of public meetings to gather input from citizens regarding proposed
criteria for evaluating Iowa lakes used for swimming will be held throughout
the state during the month of March. The list of meeting dates, times and
locations is listed below.
The proposed standards measure the transparency of the water and recommend
maintaining water clarity of a little more than 3 feet (1 meter) in at least
75 percent of the measurements. A standard of maintaining Chlorophyll-a
levels not to exceed 25 micrograms per liter in 75 percent of the
measurements taken is also being proposed. Both standards are based on
measurements taken during the summer recreational months between Memorial
Day and Labor Day.
The standards will apply to 127 lakes in Iowa that have a maintained beach,
appear on the list of Significant Public Owned Lakes or have a mean depth of
more than 3 meters (9.9 feet). A listing of the lakes and additional
information can be found at:

Water clarity is a safety issue on lakes where swimming is promoted as a
recreational activity. Poor water quality and lack of clarity can result in
not being able to spot a person having a problem in the water and at risk of
drowning, said Chuck Corell, chief of the Water Quality Bureau for the Iowa
Department of Natural Resources.
"But we have a number of studies that also show water clarity in lakes is
very much an economic factor as well," Corell said.
"In addition, we have seen research from other states that transparency of
less than one meter reduces lakefront property value by as much as 22
percent. We also have data from the 2006 Iowa State University study that
shows Iowans prefer lakes with cleaner water and those areas with better
water quality often enjoy greater economic activity and higher shoreline
property values," said Corell.
The proposed standards were developed based on recommendations written by a
Nutrient Standards Advisory committee chaired by Michael Burkart, an
associate professor at Iowa State University.
