Map of USGS gauge 14183000 and the river around it
Where NORTH SANTIAM RIVER AT MEHAMA, OR sits, with 5 other gauges 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.
Normal for Nov 5: 1,920–4,540 ft³/s (middle half of 111 years of record). Now: 1,460 ft³/s, below normal.
Below normal for this date. 1,460 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 111 years of record (1906–2026): 10th 960, 25th 1,920, median 2,980, 75th 4,540, 90th 7,800 ft³/s.
Daily means on record for Nov 5: lowest 499 ft³/s, highest 12,000 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).
Steady over 24 hours (−1.4% discharge). 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.
Species the agency lists for North Fork Santiam River: Chinook Salmon, Coho Salmon, Steelhead.

NWS observed 3.4 ft stage, 1,460 ft³/s at Nov 5, 7:15 PM PST (NWS gauge MEHO3; its stage datum can differ from the USGS gauge height).
NWS river forecast forecast issued Nov 5, 3:16 PM PST. Highest point: 4 ft, 2,290 ft³/s on Nov 14, 4:00 PM PST (Below NWS action stage).
