Map of USGS gauge 13333000 and the river around it
Where GRANDE RONDE RIVER AT TROY, OR sits 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 Grande Ronde River: 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: 783–1,060 ft³/s (middle half of 82 years of record). Now: 736 ft³/s, below normal.
Below normal for this date. 736 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 82 years of record (1945–2026): 10th 696, 25th 783, median 875, 75th 1,060, 90th 1,350 ft³/s.
Daily means on record for Nov 5: lowest 580 ft³/s, highest 2,840 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 (−1.1% 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.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
