As water warms, look for increasing mayfly activity. Right now evening caddis activity is very good here, and nymph patterns presented through heads of riffles are working. With flow at the dam around 12300 cfs (13000 cfs at Heise, 5500 cfs at Lorenzo) water is where it should be but needs to warm a bit. Expect crowds at all boat ramps. There are stories of crowding and social situations on the icon water boat ramps and on the stream, seemingly more than in past years. Much of this situation can be understood because many other local outdoor activities such as concerts and outdoor workshops are cancelled except for fishing which tends toward social distancing. Add to this that metropolitan area folks coming here to escape covid-19 situations. So unusual crowding should be expected.
