Went up to the hatchery on Saturday to have a look. Water is clear coming out of the dam and into the creek. However, there were very few steelhead up there. I spotted a group of about 15 identical sized fish (7-8lbs) sitting in the creek, but that was it.
Spoke to a guy working there and he said that the fish are definitely late this year. Seems to be the same for all rivers in CA.
As for conditions, the river looks good. It's green with good flows. Saw a couple driftboats launching at Healdsburg this morning.
