Map of USGS gauge 04189000 and the river around it
Where Blanchard River near Findlay 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: 15–65 ft³/s (middle half of 99 years of record). Now: 23.2 ft³/s, normal.
Normal for this date. 23.2 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 99 years of record (1924–2026): 10th 7.9, 25th 15, median 29, 75th 65, 90th 220 ft³/s.
Daily means on record for Nov 5: lowest 3 ft³/s, highest 1,270 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).
Falling over 24 hours: discharge down 18.9%, from 28.6 to 23.2 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.
