If the flow is not to low they will go to the Spinney dam. The deep bend below the fence is a good start ..Egg pattern trailing red serendipity worked for me. Hard fighters and leapers The browns will lay behind scarfing spawn. C&R only though..
if they aren't on that river, the Gunnison usually has a longer season, from Neversink all the way up to Almont. Just gotta time it right, so the longer Gunnison River has more opportunities, and way more fish in Blue Mesa than Elevenmile, too.
