This one was surprisingly straightforward to identify. The lack of a sclerite at the base of the lateral hump narrows the field quite a bit, and the other options followed fairly obvious characteristics to Clostoeca, which only has one species, Clostoeca disjuncta.

aren't stream gauges nifty? last year in the first week of May, a cloudburst raised the river overnight from around 500 cfs to nearly 1500. forewarned, we fished elsewhere!

The "j" will be down to 1,000 CFS by Saturday noon, March 20th. There are only a few large pools that can be fished at this level even though the water clarity is already fair to good. I have seen flies (sulfers) hatch at over 900 CFS and fish feed on them, but this is unusual. Right now I am only seeing a few black stone flies and a few olives. Water temps are also still quite low. It was 38.3 degrees yesterday morning at 8am and rose to 45.9 degrees by 5 pm. I start looking for grannom caddis when temps reach 50 degrees by their mid-morning emergence time. This usually happens between the 12th and 16th of April although in 2005 I witnessed the first fishable grannoms on April 10th, the earliest date since I started keeping records in 1980. When the Redbuds bloom so do the grannoms!
