USGS 14207200 TUALATIN RIVER AT OSWEGO DAM, NEAR WEST LINN, OR

PROVISIONAL DATA SUBJECT TO REVISION

Click to hidestation-specific text

Station operated in cooperation with Clean Water Services.

NOTE: Total chlorophyll data collected at this site use a probe 
that does not respond well to the chlorophyll in blue-green algae. 
When blue-green algae are present, the readings from this probe 
may be biased low.
