We tried the uppermost section Saturday, July 3, hiking downstream from Timothy Lake for about 2 miles. Beautiful water and nice holes, but no fish... no strikes, nada.
Harriet Lake was pretty crowded as you'd expect, so we scrambled down the hilllside where the guardrail is, about halfway between Harriet and the bridge. A couple strikes on the spinners, but nothing hooked, so I switched to a fly and got to watch some small trout repeatedly try (and miss). Anyone wishing to poke around there will probably get more action with fly right now.
