 This is the time of year also when we start paying close attention to temperatures on rivers and streams around the state. The mild winter is setting up for a tough summer on many streams, and we can find ourselves with low and warm water sooner than normal. FWP staff monitor temperatures on streams and generally will implement angling restrictions on trout streams when temperatures get above 73 degrees for more than three days in a row. That can differ depending on the species of fish that needs protected.
