Reading Nov 5, 9:00 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. We found no other gauge on the same river that publishes flow.
Water temperature, last 7 days: 169 readings from Oct 29, 10:00 PM EDT to Nov 5, 9:00 PM EST; ranging 67.3 to 71.6 °F; latest 70.9 °F.
USGS provisional data may be revised. Source: USGS instantaneous values.

Map of USGS gauge 0219897945 and the river around it
Where BACK RIVER 0.4 MI DOWNSTREAM US17, NR SAVANNAH, GA sits.
Federal guidance. Georgia DNR Wildlife Resources Division publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Georgia rule, with Georgia DNR Wildlife Resources Division's own figure added:
Stressful for trout. Water 70.9°F now; the highest in the last 24 hours was 71.6°F. At 68°F the U.S. Fish and Wildlife Service says rainbow trout “start stressing”, and the National Park Service at Grand Teton recommends that anglers “cease fishing at 2 p.m. when water temperatures are likely to exceed 68°F.” Its advice: “Fish early in the morning while the water temperature is cooler”, “Play and land fish quickly to reduce exhaustion stress” and “Keep the fish in the water as much as possible.”
High water temperatures prompt fishing advisory in Grand Teton National Park (29 July 2022)Species list not on file for this gauge. Check the Georgia DNR Wildlife Resources Division: Georgia trout fishing and weekly stocking report · Georgia fishing regulations.
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 5.6 mg/L at Nov 5, 9:00 PM EST; 7-day range 5.1–6.8 mg/L
Below EPA's coldwater mean: 5.6 mg/L is under the 6.5 mg/L 30-day mean EPA sets for coldwater fish (other life stages), though above its 4 mg/L minimum. One reading is not a 30-day mean. Wyoming Game and Fish: “Higher water temperatures lead to lower oxygen levels.”
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency) Anglers encouraged to adjust fishing practices as temperatures rise (Wyoming Game and Fish Department)pH 7.4 at Nov 5, 9:00 PM EST; 7-day range 7.1–7.7
Within EPA's freshwater range: pH 7.4 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)Turbidity 12.6 FNU at Nov 5, 9:00 PM EST; 7-day range 3.6–22.6 FNU
Water clarity: Turbidity measures the relative clarity of water: higher means murkier. No agency publishes a fishing threshold for it; compare with this gauge's own recent readings.
Turbidity and Water (U.S. Geological Survey)Specific conductance 23,600 µS/cm at Nov 5, 9:00 PM EST; 7-day range 10,400–31,300 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, 9:33 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.
