Map of USGS gauge 04200500 and the river around it
Where Black River at Elyria OH 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. 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.
This gauge is on our page for Black River, but no agency page we read lists its species.
Normal for Nov 5: 17–146 ft³/s (middle half of 82 years of record). Now: 30.8 ft³/s, normal.
Normal for this date. 30.8 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 82 years of record (1945–2026): 10th 13, 25th 17, median 36, 75th 146, 90th 476 ft³/s.
Daily means on record for Nov 5: lowest 2.8 ft³/s, highest 2,590 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 16.5%, from 36.9 to 30.8 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.
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)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.

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 0.92 ft stage, 31 ft³/s at Nov 5, 9:15 PM EST (NWS gauge ELRO1; its stage datum can differ from the USGS gauge height).
Forecasts are issued as needed during times of high water, but are not routinely available.
