Save Our Streams

The Izaak Walton League’s Save Our Streams (SOS) program helps people just like you check water quality in local creeks and streams. Share your findings with the League, and we can get a clear picture of water quality across the country – the first step in crafting water quality solutions that work. We can also help you restore your stream to good health.
