Hi everyone, and thanks in advance for fielding my question.
I live near, and fish in the Crow River in the NW metro. The Crow is infamous for high sediment and agricultural runoff pollution. I'm also hoping to help clean up the river. My question(s) is:
Would decreasing the sediment and agricultural pollution loads help increase, or even restore, redhorse spawning beds, and would this be realistically feasible through increasing the size of shoreline buffer zones?
Also, is removal of dams ultimately beneficial or harmful to native species like Redhorse? Is improved overall flowrate and subsiquent sediment outflow worth the risk of invasives (Silver/Bighead carp) taking over?
