There are so many great places to go swimming in rivers, brooks, lakes, and ponds around the Pioneer Valley, but how do you know if the water is clean enough to swim in or not?
Connecticutriver.us is a great resource for finding out about water quality in the Connecticut river watershed. They provide water quality testing data, keep a historical record of water conditions, and have an easy to use map that shows what places are safe for swimming and/or boating. They also provide information about fishing in the Connecticut river watershed and links to hiking and biking trails.
