Both.. depends on the design.. can control siltation or can allow siltation...see prior post >Do you think it is economic to build and retrofit dams that allow downstream >fish passage? (That's an issue for us in the Northwest.) My understanding is that recent spillway release experiments resulted in a subsidy in excess of a million dollars per surviving salmon. That is not economical. It would depend on the nature of a specific project as to whether retrofit or fish barging is most economical. The best way to increase salmon returns, IMHO, would be for NMFS and U.S. State Dept. to finally crack down on overfishing in the ocean, such crackdown being a difficult thing politically. But this is off our subject.
