The Pecatonica River is a freestone river in Illinois, listed as Agency-named bass water by Illinois Department of Natural Resources.
2 USGS gauges on the water report flow; Illinois Department of Natural Resources lists 1 species. 1 shop nearby are listed here.
Pecatonica River is a freestone river in Illinois.
Pick one of its USGS gauges and hear from us when the flow moves into or out of its usual range for the date, or crosses a flow you set. We check the public USGS reading every 2 hours and email only when it crosses, at most once every 6 hours. Flow alone is not a fishing forecast or a safety call.
Signed in: one step. Otherwise we email a confirmation link first. Every alert has one-click links to stop it.
Start from the agency's public access map. Nothing on this page grants or implies access: check the agency map, posted signs and landowner permission before you fish.

Seasons, limits, special regulations and closures for each reach are on the agency pages below. Read them before you go.
Each comes from the agency's own published list; where the list names a reach it is quoted. A designation applies to the listed reach, not necessarily the whole water. Listed in the finder under bass.

Above normal for this date. 1,130 ft³/s is between the 75th and 90th percentiles of daily mean flow for Nov 5 at this gauge over 112 years of record: 10th 331, 25th 480, median 664, 75th 1,068, 90th 1,557 ft³/s.

Normal for Nov 5: 807–1,920 ft³/s (middle half of 43 years of record). Now: 1,700 ft³/s, normal.
Normal for this date. 1,700 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 43 years of record: 10th 580, 25th 807, median 1,290, 75th 1,920, 90th 2,698 ft³/s.
Daily means on record for Nov 5: lowest 490 ft³/s, highest 5,140 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 (+5.6% 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.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
NWS observed 5.75 ft stage, 1,750 ft³/s at Nov 5, 4:00 PM CST (NWS gauge SIRI2; its stage datum can differ from the USGS gauge height).
Forecasts are issued as needed during times of high water, but are not routinely available.

No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. Illinois DNR publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Illinois rule: 68°F.
Species the agency lists for Pecatonica River: Smallmouth Bass.

Flood categories: action stage, minor, moderate and major flooding (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.

Checked Nov 5, 5:18 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.
