To the editor:

The curly-leaf pondweed is about to make its annual appearance at Lone Star Lake, and area anglers beseech lake residents and Douglas County Public Works not to spray herbicides on the pondweed. Instead, residents should allow the pondweed to wilt naturally. Once the water temperature reaches the low 70s in June, the pondweed will begin to diminish, and by July 4, it will virtually disappear.

Anglers also implore lake residents and Public Works officials not to employ such herbicides as Round Up and Rodeo around Lone Star and other nearby waterways.

Some knowledgeable observers maintain that many of the waters that Kansans fish, boat and swim in have been adversely affected by herbicides and other agricultural chemicals. Therefore, county residents and officials need to develop methods that will stop this pollution.
