Map of USGS gauge 02147310 and the river around it
Where CATAWBA RIVER AT GREAT FALLS, SC sits, with 3 other gauges on the same river.
Not over South Carolina DNR's 70°F line. Water 65.5°F now; the highest in the last 24 hours was 66.2°F. South Carolina DNR gives 52 to 62°F as optimum (“when water temperatures are optimum (52-62° F), trout fishing can be productive throughout the day”) and 70°F as the line above which water stresses trout.
Rising over 24 hours: gauge height up 0.87 ft. 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 South Carolina Department of Natural Resources: South Carolina trout stocking summary · South Carolina hunting and fishing regulations.
Rising water. Rising over the last 24 hours (gauge height up 0.87 ft). Keep your way back to the bank in sight and watch the level while you fish. “Rising” is our rule of thumb: more than 10% in discharge or 0.2 ft of gauge height in 24 hours, not a USGS or NWS class.
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 9.6 mg/L at Nov 5, 10:45 PM EST; 7-day range 8.9–10.4 mg/L
Enough oxygen for coldwater fish: 9.6 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)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, 10:52 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.
