Colorado Stream Update: The lower sections have been heating up!

Current Conditions at Lower Colorado:

The Colorado river is giving up some great days in almost every section. Flows have been consistently trending downwards. Water clarity is ideal! Fish are being found in slow seams and around shelves with soft riffles. There are some fish looking up with sporadic hatches of mahogany duns, midges and caddis but most eats remain subsurface. A good hopper-dropper rig that has a deep enough nymph has been picking up some nice fice. Patterns like princes, 20-inchers, leeches and soft hackle flies are all good choices. Streamers are hit and miss but have put some big fish in the bag. Make sure your streamers are getting down deep, olive and black seem to be the colors of choice.

This is one of the best times of year to be on the water! The flows on the Colorado are great for both wade and float fishing.  The fishing is good.  Clear skies and 60+ degree weather. The water temperature was between 56-59 degrees and Slightly Off.
