Reading Nov 5, 7:00 PM CST · 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: HARPETH RIVER BELOW FRANKLIN, TN (USGS 03432400, 0.8 miles away).
Water temperature, last 7 days: 169 readings from Oct 29, 8:00 PM CDT to Nov 5, 7:00 PM CST; ranging 60.6 to 67.6 °F; latest 64.2 °F.
USGS provisional data may be revised. Source: USGS instantaneous values.

Map of USGS gauge 034324146 and the river around it
Where HARPETH RIVER AT MILE 81.33 NR BERRYS CHAPEL, TN sits, with 6 other gauges on the same river.
Federal guidance. Tennessee Wildlife Resources Agency publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Tennessee rule:
Under the federal 68°F line. Water 64.2°F now; the highest in the last 24 hours was 66.2°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.”
High water temperatures prompt fishing advisory in Grand Teton National Park (29 July 2022) (National Park Service)Species list not on file for this gauge. Check the Tennessee Wildlife Resources Agency: Tennessee trout fishing and stockings · Tennessee 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 4.1 mg/L at Nov 5, 7:00 PM CST; 7-day range 1–9.3 mg/L
Below EPA's coldwater mean: 4.1 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)Specific conductance 366 µS/cm at Nov 5, 7:00 PM CST; 7-day range 282–664 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, 7:19 PM CST; 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.
