Residents around Indian Lake in Worcester, Massachusetts, are raising concerns after a spike in fish deaths following the recent application of aquatic herbicides.

Fishermen, boaters and picnickers familiar with Fox Valley Lake north of Kahoka might be a little surprised to see how the lake looks. The 108-acre body of water is 8 feet lower than normal — and will remain at that level until the beginning of March. It is all part of an ambitious plan by
Warmer weather and water temperatures are spurring the growth of aquatic plants across Wisconsin and increasing calls from waterfront property owners for help in controlling the plants.
