Oregon — Fish returning to Foster Dam continue to reflect steady annual runs, as the Oregon Department of Fish and Wildlife (ODFW) released its latest weekly recreation report highlighting spring fishing conditions, regulatory updates, and environmental concerns.
At Foster Dam, adult salmon and steelhead enter a fish ladder on the south side before being held in a trap for processing by hatchery staff. Operations occur one to three times per week depending on seasonal returns. On average, the system collects about 4,000 spring Chinook, 4,700 summer steelhead, and 670 winter steelhead each year.
Hatchery crews retain select hatchery fish for broodstock—about 500 pairs of Chinook and 700 pairs of summer steelhead—while unmarked spring Chinook and winter steelhead are released upstream into native habitat along the South Santiam River.
Across Oregon, ODFW reports that spring fishing opportunities are expanding, including a limited reopening of Chinook retention below Bonneville Dam from April 11 through April 13. Anglers are allowed to keep two adult hatchery salmonids per day, with only one Chinook permitted.
The agency also warned of emerging environmental risks after invasive golden mussels were discovered on a watercraft entering Oregon from California. Officials say the species poses a serious threat to ecosystems and infrastructure by consuming key food sources and damaging water systems.
Drought conditions are already affecting fish stocking plans in some areas, with warmer and shallower waters forcing hatchery fish to be redirected. Meanwhile, trout stocking, kokanee fishing, and early spring angling opportunities remain strong across multiple regions.
ODFW also reminded anglers and hunters of seasonal regulations, reporting requirements, and upcoming spring turkey and bear hunting seasons, urging outdoor enthusiasts to check local conditions before heading out.
