Map of USGS gauge 14137000 and the river around it
Where SANDY RIVER NEAR MARMOT, OR sits, with 1 other gauge on the same river and our water's map point.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer: the trout lines ODFW uses are 68°F and 70°F.
Species the agency lists for Sandy River: Chinook Salmon, Coho Salmon, Steelhead.
Source: Salmon and steelhead sport catch waterbodies (2025 expanded catch by month and waterbody code) (Oregon Department of Fish and Wildlife).
Normal for Nov 5: 464–1,330 ft³/s (middle half of 114 years of record). Now: 265 ft³/s, much below normal.
Much below normal for this date. 265 ft³/s is below the 10th percentile of daily mean flow for Nov 5 at this gauge over 114 years of record (1912–2026): 10th 323, 25th 464, median 802, 75th 1,330, 90th 2,540 ft³/s.
Daily means on record for Nov 5: lowest 233 ft³/s, highest 10,900 ft³/s.
Classes as USGS labels them (hyswap: flow categories (WDFN_stats schema) (U.S. Geological Survey) ); percentiles from the USGS daily statistics (U.S. Geological Survey) (approved daily means; the reading is provisional and instantaneous).
Rising over 24 hours: discharge up 19.4%, from 222 to 265 ft³/s. Rising or falling means a change of more than 10% in discharge (or 0.2 ft of gauge height) over 24 hours; our rule of thumb, not a USGS class.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
Flood categories: action stage, minor, moderate and major flooding (National Weather Service)Rising water. Rising over the last 24 hours (discharge up 19.4%). Keep your way back to the bank in sight and watch the level while you fish. “Rising” is our rule of thumb: more than 10% in discharge or 0.2 ft of gauge height in 24 hours, not a USGS or NWS class.
Turn Around Don't Drown. “A mere 6 inches of fast-moving flood water can knock over an adult.” No flow number makes a crossing safe; if in doubt, stay out.

NWS observed 690 ft stage, 265 ft³/s at Nov 5, 6:15 PM PST (NWS gauge SRMO3; its stage datum can differ from the USGS gauge height).
NWS river forecast forecast issued Nov 5, 4:01 PM PST. Highest point: 690 ft, 509 ft³/s on Nov 10, 10:00 PM PST (Below NWS action stage).
