Transcript: Iowa Lake Restoration Program

The Iowa Department of Natural Resources is cleaning dozens of Iowa lakes this summer as part of its ongoing lake restoration program.

This is the Iowa Environmental Focus.

The Iowa DNR has selected 35 Iowa lakes and watersheds for restoration with the goals of improved water quality, a balanced aquatic community and improved fishing and swimming. Their 2013 report states that many Iowa lakes suffer from excessive algol growth and sedimentation.

The DNR plans to work with local towns and watershed groups to develop action plans, including marsh rehabilitation, wetland reconstruction and lake dredging. Similar projects at Clear Lake, Storm Lake and Lake MacBride have enhanced recreation opportunities, putting them in the top five most visited lakes in the state.

Northern Iowa sees cases of ‘swimmer’s itch’

According to the Iowa Department of Natural Resources (DNR), swimmers who frequent Iowa’s natural lakes should be wary of ‘swimmer’s itch’.

The condition is caused by parasitic flatworms that penetrate human skin before immediately dying; this causes itchy, red welts to appear that may persist for up to a week.

So far, cases have been reported from Black Hawk Lake and Crystal Lake.

Swimmer’s itch can be prevented by avoiding areas rife with aquatic plants, reducing time spent in the water, and drying off quickly after swimming. The condition does not generally require medical attention, and can be treated with calamine lotion and an antihistamine.
