The U.S. Army Corps of Engineers has temporarily closed both Ives Run Beach on Hammond Lake and South Shore Beach on Cowanesque Lake after a routine water sample from each of the swimming areas revealed elevated levels of E. coli bacteria.

Bacteria levels in freshwater bodies like lakes fluctuate daily based on precipitation, water inflow, and the presence of humans or waterfowl. Contamination typically originates near the shoreline rather than in deeper water. USACE conducts water quality tests weekly to closely monitor these changing conditions.

USACE manages more than 400 lake and river projects nationwide and welcomes millions of visitors each year. 🚣 While those visits create opportunities for recreation and family memories, preventable tragedies still occur on public waters annually, many involving people not wearing life jackets.

⚠️ “The recreation areas operated by the U.S. Army Corps of Engineers are provided for visitors to get outside, enjoy nature and create wonderful memories,” said Maj. Gen. Jason E. Kelly, USACE deputy commanding general for civil and emergency operations. “If your plans this summer include activities on the water, take appropriate precautions. Wear a life jacket, swim in designated areas, recreate responsibly and encourage your family and friends to do the same.”

*Hammond Lake Only*

"Notice to anglers: It's unlawful to fish in the panfish enhancement special regulation water except in compliance with size and daily limits.

These regulations are intended to increase the number, quality, and size of panfish through the use of minimum length limits on crappies (both black and white).

When these regulations apply to more than one species in the same waterway, the daily limit is 20 for each species with the total daily limit not to exceed 50 panfish combined. For these purposes, panfish includes carp, catfish, suckers, Rock Bass and White Bass."
