NOTICE: A recreational use advisory was issued by the Oregon Health Authority for Detroit Lake and the North Santiam River below due to high levels of a toxin caused by a cyanobacteria bloom. For more information visit this link. ‌

River levels best for fishing are at or below 3,000 cfs, and the river is currently running at around 1,250 cfs at the gauge in Mehama. These flows should be the norm throughout the summer months. ‌

Most of the summer steelhead and spring Chinook have migrated up into the river and are working their way towards the upper sections of the river where water temperatures are coolest. This year's summer steelhead run is the strongest since 2016 with over 4,600 adults already counted at Stayton. As of July 27, they have counted over 18,000 adults passing above Willamette Falls.‌

The spring chinook run is just about over for the year. Most of the fish destined for the North Santiam are now in the river. Nearly 21,000 adults have been counted at Willamette Falls so far.
