Reading Nov 5, 10:00 PM EST · provisional USGS data
No flow at this gauge. USGS does not publish discharge here, so there are no flow statistics either; it reports what is shown. Flow on the same river: Big Darby Creek at Darbyville OH (USGS 03230500, 14.5 miles away).
Water temperature, last 7 days: 168 readings from Oct 29, 11:30 PM EDT to Nov 5, 10:00 PM EST; ranging 55.6 to 61 °F; latest 59.2 °F.
USGS provisional data may be revised. Source: USGS instantaneous values.

Map of USGS gauge 395339083130100 and the river around it
Where Big Darby Creek above Georgesville OH sits, with 1 other gauge 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 59.2°F now; the highest in the last 24 hours was 60.3°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.”
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.
Cold water. Water 59.2°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 7.5 mg/L at Nov 5, 10:00 PM EST; 7-day range 7.3–14.4 mg/L
Enough oxygen for coldwater fish: 7.5 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 7.9 at Nov 5, 10:00 PM EST; 7-day range 7.8–8.6
Within EPA's freshwater range: pH 7.9 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 584 µS/cm at Nov 5, 10:00 PM EST; 7-day range 563–849 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.
The National Weather Service has no flood-stage gauge here, so no official flood category is shown.
Checked Nov 5, 11:27 PM EST; readings refresh at most every 15 minutes and statistics daily. Provisional USGS data can be revised. Conditions change: re-check before you go. This is general guidance, not a fishing forecast, a safety guarantee or a statement about access.
