Map of USGS gauge 14187500 and the river around it
Where SOUTH SANTIAM RIVER AT WATERLOO, OR sits, with 4 other gauges on the same river and our water's map point.
Normal for Nov 5: 935–3,660 ft³/s (middle half of 106 years of record). Now: 1,170 ft³/s, normal.
Normal for this date. 1,170 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 106 years of record (1906–2026): 10th 399, 25th 935, median 2,140, 75th 3,660, 90th 6,010 ft³/s.
Daily means on record for Nov 5: lowest 106 ft³/s, highest 11,900 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).
Steady over 24 hours (−0.8% 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.
Under ODFW's 68°F line. Water 56.7°F now; the highest in the last 24 hours was 57°F. That is under the 68°F at which ODFW says trout, steelhead and salmon “start to feel stressed”. “Fish early in the morning when water temperatures are cooler and fish are more active.”
5 tips for fishing in hot water (Oregon Department of Fish and Wildlife)Species the agency lists for South Fork Santiam 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).
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)Cold water. Water 56.7°F. NWS: “Cold shock can be just as severe and dangerous from water temperatures of 50-60°F (10-15°C) as it is from water at 35°F (2°C).” “Always wear a life jacket in and around the water.”
Cold Water Hazards and Safety (National Weather Service)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.
Turn Around Don't Drown (National Weather Service)Dissolved oxygen 10.6 mg/L at Nov 5, 6:00 PM PST; 7-day range 9.9–10.9 mg/L
Enough oxygen for coldwater fish: 10.6 mg/L meets the 6.5 mg/L EPA sets for coldwater fish (other life stages; eggs and fry need a 8 mg/L minimum).
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency)Turbidity 2.3 FNU at Nov 5, 6:00 PM PST; 7-day range 0.9–6.7 FNU
Water clarity: Turbidity measures the relative clarity of water: higher means murkier. No agency publishes a fishing threshold for it; compare with this gauge's own recent readings.
Turbidity and Water (U.S. Geological Survey)Guidance from the readings above and the published thresholds named with each line; not a fishing forecast, a safety guarantee or a statement about access. Local rules and closures come first.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
NWS observed 3.17 ft stage, 1,170 ft³/s at Nov 5, 6:15 PM PST (NWS gauge WTLO3; its stage datum can differ from the USGS gauge height).
NWS river forecast forecast issued Nov 5, 3:16 PM PST. Highest point: 3.38 ft, 1,420 ft³/s on Nov 14, 4:00 PM PST (Below NWS action stage).
