DES MOINES, Iowa — It's going to be a pretty hot Independence Day weekend, but folks thinking about taking a dip at Saylorville Lake should probably find a different place to swim.
The U.S. Army Corps of Engineers in the Rock Island District says there has been a "visible increase" in algae levels at the lake since Monday, so visitors should avoid swimming there at this time.
The algae results, however, are below the state's actionable threshold.
Water quality tests at the lake are done weekly through a contract with Iowa State University. Officials with the U.S. Army Corps of Engineers say they will be looking into increasing the frequency of these tests to provide visitors with more accurate results in the future.
