FLOW: 4280 cfs in Glenwood Springs
WATER CONDITIONS: Clear one day, blown the next as we warm up
OVERALL RATING: 3 out 10 if clear, less if muddy and off-color
FOOD SOURCES PRESENT: BWOs, Caddis, Golden Stoneflies, Midges
THE LOW DOWN: Spawning Closures are in effect from March 15 to May 31st at Elk Creek upstream to US6 Bridge, Canyon Creek upstream to I70 Bridge.
Hatches have turned on in a major way over the last week, we now are seeing plenty of caddis and BWOs, plus a few random stoneflies as we warm up. The fish are on the caddis and BWOs.
Watch the foam lines in the slower sections of the river, the bugs can accumulate there and the fish relate to them some days better than others.
You should see more caddis on the bright days and mayflies on the cloudy ones.
No need to put on the river super early, let it warm up a bit and get those bugs moving around.

HINTS: Don't focus on just the large slow runs. The fish tend to move into the faster and shallower water when the hatches are coming off. If the fish aren't eating deep, shallow up those nymph rigs and see if they're suspended.
