“View Adult Salmon Swim!”
The Winchester Dam was built in November 1890 and is in the National Register of Historical Places. In 1945 a more permanent fish ladder and the first fish counting station on Winchester Dam was built. In 1964, new public and counting windows were constructed in the upper pools of the ladder. These viewing areas were improved again in the 1980’s. Since the fall of 1991 all counts have been conducted from a 24 hour video camera. Biologists use the fish counts to monitor populations, make management decisions, and recommend angling regulations. A video camera records fish passage, and a technician views the tapes to record species and size, fin clips, and any predator marks. The primary species of anadromous fish counted at Winchester Dam are summer and winter steelhead, spring chinook salmon, and coho salmon. Adult fish can be observed swimming upstream through a fishway on the famous North Umpqua River. Species present at different times of the year include steelhead, chinook salmon, coho salmon, trout, lamprey, northern pike minnow and suckers.
