Yes, the spring freshet...certainly the reservoirs are used to control flooding, so some of the traditional flood plain areas that would have been spawning areas are no longer flooded every spring the way they would have been 200 years ago. I would say that the spring freshet is not as volatile. The reservoirs are used to control flooding so we don't flood as much of the flood plain each year.
