Actually, it is my experience that all the rivers on the west side are sort of "late" this year... Not only the Cedar, but also the other usual suspects that start rendering fruits by mid Jun after the run off have been effing hard so far. At the same time, lakes that traditionally shut off by June (trout wise, I mean) are still on. It feels more like end of April than end of June.General consensus is the season has been really bad so far. I'll give it a couple more goes until alpine lakes are a game.
The Cedar was 55 degrees yesterday, a couple of degrees below average but not terribly colder, so I don't know what is going on. My bet is that something is off with the food chain and the insects.
