Welcome to OFF. Here's that section of the ODFW Recreation Report:
SANTIAM RIVER (SOUTH FORK): steelhead, Chinook , bass
Flows in the South Santiam below Foster dam have been fluctuating around 1,000 cfs at Waterloo as of May 4. Water releases out of Green Peter reservoir are being reduced for the next few weeks to ensure adequate filling before the summer, which should make for excellent fishing conditions in the interim below Foster dam.
New summer steelhead and spring Chinook have begun to arrive at Willamette Falls but it will take a few weeks before the majority of them arrive in the basin. Winter steelhead are in the basin now and can be found throughout the river. So far, 107 winter steelhead, 28 summer steelhead and 255 spring Chinook have entered the trap below Foster as of May 4. Best sections to fish are from Wiley Creek to Pleasant Valley boat ramps, around Waterloo County Park, and from Lebanon down to the confluence with the North Santiam.
Closed to trout fishing until May 23, 2015.
