These are just ideas......


I think it takes longer for the fish to stabilize after the flow goes up.

In the late Summer and Fall when it rains the fish can turn on.

When the flow goes up migratory fish usually move up river.


Having the water go up and down dramatically every day can't be good for the ecosystem.

Many years ago we had an aquatic insect class on the South Fork of the America river at Lotus.

Mike and Kristine Fong put on the class for my shop and the flows then use to go up and down daily.

Mike turned over many rocks during the low flow stage and we did not see hardly any insect life.
