3 USGS gauges on the water report flow; Illinois Department of Natural Resources lists 1 species. 1 guide and 4 shops nearby are listed here.
West Branch DuPage 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.

Normal for Nov 5: 15–44 ft³/s (middle half of 65 years of record). Now: 23.1 ft³/s, normal.
Normal for this date. 23.1 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 65 years of record (1962–2026): 10th 5.9, 25th 15, median 20, 75th 44, 90th 68 ft³/s.
Daily means on record for Nov 5: lowest 1 ft³/s, highest 204 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 (−8.3% 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 3.88 ft stage, 22 ft³/s at Nov 5, 3:55 PM CST (NWS gauge WBDI2; its stage datum can differ from the USGS gauge height).

Normal for Nov 5: 39–98 ft³/s (middle half of 58 years of record). Now: 45.8 ft³/s, normal.
Normal for this date. 45.8 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 58 years of record (1969–2026): 10th 26, 25th 39, median 55, 75th 98, 90th 247 ft³/s.
Daily means on record for Nov 5: lowest 13 ft³/s, highest 496 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).
Falling over 24 hours: discharge down 13.4%, from 52.9 to 45.8 ft³/s. 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 7.68 ft stage, 45 ft³/s at Nov 5, 4:15 PM CST (NWS gauge WRNI2; 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.

Normal for Nov 5: 46–186 ft³/s (middle half of 38 years of record). Now: 97.1 ft³/s, normal.
Normal for this date. 97.1 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 38 years of record (1989–2026): 10th 36, 25th 46, median 76, 75th 186, 90th 375 ft³/s.
Daily means on record for Nov 5: lowest 24 ft³/s, highest 649 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 (−4.8% 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 4.26 ft stage, 81 ft³/s at Nov 5, 4:15 PM CST (NWS gauge NAWI2; its stage datum can differ from the USGS gauge height).
Forecasts are not available. Only observed stages are available for this point.

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 West Branch DuPage 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.
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.
Checked Nov 5, 5:21 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.
