The smaller streams are still pushing a lot of water with runoff but lower level streams are beginning to come into form. It's best to lay eyes on a stream first to see if you are able to wade it. It will vary from area to area on what is available! Nymphing early but throwing small attractor patterns in the afternoon should produce some quality fishing.
The Month Ahead:
As run off subsides small stream fishing will become very, very good in late June and early July. Attractor dry flies are usually all that is needed.
Long Term Fishing Forecast:
Most small streams fish best in the summer months once waters recede from run off in late June or early July
