CARTER LAKE, Iowa (AP) — An Iowa official says there’s no easy solution or quick fix to a persistent algae problem at a lake in western Iowa. Chris Larson with the state Department of Natural Resources told the Carter Lake City Council that unusual weather over the last three years have made it difficult to clean up Carter Lake.

Larson said routine maintenance from the city’s mechanical harvesters may be the best long-term solution for the lake. The Council Bluffs Nonpareil reports that DNR recommended the city begin using harvesters in mid-April or early May. Priority areas for algae removal will be discussed at a later date.
