The mighty MO is super fun right now!

Its spring... the water is still cold. We always talk about shiny and tiny, and shrink it and pink it. Scuds, Sow Bugs, and BWO are getting the job done. Might see some PMD's coming off soon.

The two handers and streamer fishing are also working well. The flow has been around 3,000 all spring.
