Alsea River Fish Report for 9-3-2025
Alsea River Report
Alsea River - Alsea, OR

The OHA issued a July 31 advisory due to the presence of cyanobacteria and now an Aug. 15 update due to very high saxitoxin (paralytic shellfish toxin) levels. ODFW recommends that people avoid harvesting and eating softshell and bay clams harvested in the estuary!
Fall Chinook is finally back open on the coast! It is still early in the season, but there are likely a few fish around the bay at this time. We have had more reports of fish being caught in the bay but without any significant rainfall this last week it still is slow going in the Alsea. Weeds are also prevalent this time of year so remember to check your hooks frequently as you troll for Salmon!
Coastal Cutthroat will be distributed throughout the Alsea basin and provide an excellent and fun opportunity during the remainder of the summer months. As we move into August cutthroat will continue moving throughout the basin. With the lower waters, hitting the river in the early mornings before temperatures rise can be a good bet for landing cutthroat in the basin! Anglers are reminded/ to check the regulations for use of bait and whether there are closed streams.
