What this level means general guidance

Normal for Nov 5: 235–349 ft³/s (middle half of 85 years of record). Now: 400 ft³/s, above normal.

Above normal for this date. 400 ft³/s is between the 75th and 90th percentiles of daily mean flow for Nov 5 at this gauge over 85 years of record (1942–2026): 10th 192, 25th 235, median 294, 75th 349, 90th 432 ft³/s.

Daily means on record for Nov 5: lowest 108 ft³/s, highest 534 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.

Official flood stage · National Weather Service

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 2.75 ft stage, 411 ft³/s at Nov 5, 3:15 PM MST (NWS gauge RVTW4; its stage datum can differ from the USGS gauge height).

Action stage: 7 ft
Minor flood: 8 ft
Moderate flood: 10 ft
Major flood: 11 ft

Forecasts are issued as needed during times of high water, but are not routinely available.

Conditions for fishing general guidance

No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer: the trout lines Wyoming Game and Fish uses are 65°F, 68°F and 70°F.

Species

Species the agency lists for Popo Agie River: Brown Trout, Mountain Whitefish, Rainbow Trout, Sauger.

Safety

Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
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, 4:21 PM MST; 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.

Reading the gauges…

Check any river's flow

Follow Popo Agie River for flow alerts

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.

Follow this water

Signed in: one step. Otherwise we email a confirmation link first. Every alert has one-click links to stop it.

Where to fish

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.

Fish these abroad

Matched on the fish the agencies list for both waters first, then the same water type, an official designation or flagship listing on both, and a similar mapped size where USGS hydrography covers both.

At most two waters per country. A shared fish is a listing, not a promise: presence varies by reach and season.

Like the Popo Agie River? Same fish, overseas.

A water page organises discovery. It does not assert public access, legal access, current fish presence, guide availability or fishing conditions.

Flows, gauge statistics and flood stages come from USGS and the National Weather Service when the page is shown. Regulations, stocking, species and season statements link to the agency that publishes them; this page copies only the species names and the quoted sentences. Guide and shop listings come from the Legendary directories. Position: a point on the mapped channel of “Popo Agie River”, halfway along its length in Wyoming, from the USGS high-resolution hydrography (NHDPlus HR), read 4 Nov 2026. It marks the water, not a particular access or reach. Water type is our own classification.

What this level means general guidance

Normal for Nov 5: 235–349 ft³/s (middle half of 85 years of record). Now: 400 ft³/s, above normal.

Daily means on record for Nov 5: lowest 108 ft³/s, highest 534 ft³/s.

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.

Official flood stage · National Weather Service

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 2.75 ft stage, 411 ft³/s at Nov 5, 3:15 PM MST (NWS gauge RVTW4; its stage datum can differ from the USGS gauge height).

Action stage: 7 ft
Minor flood: 8 ft
Moderate flood: 10 ft
Major flood: 11 ft

Forecasts are issued as needed during times of high water, but are not routinely available.

Conditions for fishing general guidance

No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer: the trout lines Wyoming Game and Fish uses are 65°F, 68°F and 70°F.

Species

Species the agency lists for Popo Agie River: Brown Trout, Mountain Whitefish, Rainbow Trout, Sauger.

Source: Red Ribbon streams (WGFD stream classification: Red, 300-599 lbs trout/mile) (Wyoming Game and Fish Department).

Safety
