| Notes | Numerous statistics, from creel censuses to catch-and-effort statistics. Includes data from the Tenmile Lakes system . "In late 1950 the Umpqua watershed experienced one of its greatest floods of recent times. The magnitude of the freshet was such that many gravel bars were shifted, some being moved several hundred feet. As it occurred shortly after the spring chinook spawning period, it was suspected that some loss of spawn resulted.. . The flood came at the peak period of downstream migration. After it had receded, many young fish were found to have perished on the lowlands adjacent to the river. All attempts at salvage proved to be futile. The kill of immature rough fish was extremely heavy." (p.9) |
