We have been getting some unusual late spring rains here in Northern California. This is causing heavy runoffs and overflows at a time that it never happens. This morning I found fingerling Bluegills swimming about 1/2 mile out into a field on my ranch. They got there swimming in what amounts to sheet flows of water barely deep enough to cover them. I've seen it before so it didn't surprise me. My point is only that the little buggers can travel far distances in almost no water when forced to do so.
