Fishing Conditions

April 24, 2018

 Yesterdays wet weather bumped the river, it was topping out at 600 cfs last night. With a warm week to follow the river may rise even more. Don't bother going up into the National Forest reaches, there's still a lot of snow. Food is most definately being sturred and the banks are beginning to get scoured with rising water so make sure you bring a few San Jaun variations. There are stoneflies here and they would make a good lead bug in these conditions. Baetis droppers should also be with you. The water temps are below what they need to hatch but they will be getting flushed out of the rocks as the flow increases.
