Map of USGS gauge 01125490 and the river around it
Where LITTLE RIVER AT HARRISVILLE, CT sits.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. Connecticut DEEP publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Connecticut rule, with Connecticut DEEP's own figure added: 68°F.
Species list not on file for this gauge. Check the Connecticut Department of Energy and Environmental Protection (DEEP): Connecticut trout stocking maps · Connecticut freshwater fishing regulations.
Normal for Nov 5: 10–60 ft³/s (middle half of 25 years of record). Now: 25.1 ft³/s, normal.
Normal for this date. 25.1 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 25 years of record (1962–2026): 10th 4.4, 25th 10, median 22, 75th 60, 90th 110 ft³/s.
Daily means on record for Nov 5: lowest 3.1 ft³/s, highest 244 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).
Steady over 24 hours (+4.1% discharge). 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.
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)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, 8:24 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.
