some of what I have learned about 'springers'...most of the coastal rivers are not long enough and/or do not have consistent summer water flows and deep pools for true spring chinook to hold in...most coastal rivers are not open for chinook fishing until either May 23 or Aug 1.
ODFW is doing several things to improve spring chinook fishing on the coast, from new CMP (Coastal Multi-Species Conservation and Management Plan):
"Chinook populations in this SMU (Columbia river south to Elk river) include early (returning in the spring or summer) and late (returning in the fall) adult components. In those Coastal basins that do not extend into the Cascades, early and late returning Chinook are considered in this plan to be one population, given that: a) there are fewer isolating mechanisms between the two life history components; b) these basins are not naturally conducive to independent spring or summer Chinook populations (as evidenced by both the lack of snow-fed summer water and the limited presence and scope of early Chinook runs); and c) existing data do not strongly support a bi-modal distribution in returns. This determination is subject to change with new genetic or spatial and temporal distribution information (e.g., the Nehalem summer run is potentially an independent and isolated population). Early component fish in several populations provide diversity and some fishing opportunities that are important to protect and enhance where possible. In order to distinguish different run timing in Chinook populations, early components are referred to as spring-run or summer-run Chinook (depending on the location). The more abundant late component is referred to as fall-run Chinook. Independent populations of spring returning Chinook are called spring Chinook (as opposed to spring-run Chinook)."
'Springer' Hatchery plantings going forward under CMP:
Trask-400K, Nestucca- 200K, L.Nestucca-30K (new fishery), Yaquina-100K (new run), N.Umpqua-342K, CoosBayFrontal-100K(new run)
Hatchery Spring Chinook Actions
• L Nestucca ChS - look into tidewater fishery (develop acclimation site) and stock 30k if feasible (new production)
• Yaquina and Coos ChS - program size based on number of fish needed to evaluate the new programs’ fishery contribution and impacts to wild populations; contribution and impacts will be reviewed in 5 years, which may lead to program increases or decreases
• New Yaquina ChS program will be monitored well enough to determine effects to nearby wild ChS life-history variants (Siletz and Alsea) and include surveys that look for carcasses (as opposed to float surveys that count live fish) to determine the stray rate of hatchery fish into the wild spawning areas
• N Umpqua ChS - remove hatchery fish at Rock Creek Hatchery Dam trap20; account for hatchery fish that pass above Winchester Dam
