Map of USGS gauge 04189260 and the river around it
Where Blanchard River at Ottawa OH sits, with 5 other gauges on the same river.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. Ohio Division of Wildlife publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Ohio rule: 68°F.
Normal for Nov 5: 29–320 ft³/s (middle half of 17 years of record). Now: 41.7 ft³/s, normal.
Normal for this date. 41.7 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 17 years of record (2010–2026): 10th 14, 25th 29, median 50, 75th 320, 90th 1,160 ft³/s.
Daily means on record for Nov 5: lowest 8.82 ft³/s, highest 4,170 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 (+9.4% 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.
