Map of USGS gauge 03228300 and the river around it
Where Big Walnut Creek at Sunbury OH sits, with 2 other gauges on the same river.
Federal guidance. 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:
Under the federal 68°F line. Water 57.7°F now; the highest in the last 24 hours was 60.1°F. That is under the 68°F at which the National Park Service, at Grand Teton National Park, recommends anglers stop fishing in the afternoon (“cease fishing at 2 p.m. when water temperatures are likely to exceed 68°F”). Water warms through the afternoon, so check again later in the day: “Carry a pocket thermometer to monitor water temperature.”
Normal for Nov 6: 3–39.1 ft³/s (middle half of 38 years of record). Now: 128 ft³/s, much above normal.
Much above normal for this date. 128 ft³/s is above the 90th percentile of daily mean flow for Nov 6 at this gauge over 38 years of record: 10th 0.44, 25th 3, median 7.96, 75th 39.1, 90th 119 ft³/s.
Daily means on record for Nov 6: lowest 0 ft³/s, highest 2,060 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 24.3%, from 169 to 128 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.
Species list not on file for this gauge. Check the Ohio Department of Natural Resources, Division of Wildlife: Ohio steelhead stockings 2021-2025 · 2026-27 Ohio fishing regulations.
Flow far above normal. Above the 90th percentile of daily mean flow for this date (USGS class “much above normal”), from 38 years of record. Expect higher, faster water than usual for the season.
hyswap: flow categories (WDFN_stats schema) (U.S. Geological Survey) Statistics documentation (percentiles of daily mean discharge) (U.S. Geological Survey)Cold water. Water 57.7°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 8.8 mg/L at Nov 5, 11:00 PM EST; 7-day range 7.7–12 mg/L
Enough oxygen for coldwater fish: 8.8 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)pH 7.7 at Nov 5, 11:00 PM EST; 7-day range 7.7–8.4
Within EPA's freshwater range: pH 7.7 is within the 6.5–9 range EPA gives for freshwater aquatic life.
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency)Specific conductance 492 µS/cm at Nov 5, 11:00 PM EST; 7-day range 475–730 µS/cm
Dissolved ions: Specific conductance rises with the ions dissolved in the water. No fishing threshold is published for it; compare with this gauge's own recent readings.
Conductivity (Electrical Conductance) 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.
NWS observed 5.57 ft stage, 132 ft³/s at Nov 6, 12:00 AM EST (NWS gauge SBYO1; its stage datum can differ from the USGS gauge height).
NWS has not set flood categories for this gauge.
Forecasts are not available. Only observed stages are available for this point.
