1. North Platte River – Miracle Mile
Central Wyoming
FLOW: 630 cfs →
AIR TEMP: 37°-55°F
The North Platte River was flowing on the report date at 630 cfs CFS (normal) with a stable trend. The Verdict: Excellent Fishing Conditions This week’s forecast shows temperatures ranging from 37-55°F, calm winds create ideal conditions for dry fly fishing.
Insect Activity: Dam releases create stable tailwater conditions ideal for winter fishing. Midges and small nymphs remain active throughout the season, with streamer patterns effective in deeper runs. Nymph patterns (#18-24) are most productive.
Where to Fish: Higher tailwater flows create more holding water. Target deeper runs, tailouts, and slower side channels where fish can hold out of the main current. Excellent conditions make multiple water types productive—vary your approach throughout the day.

Whether you’re targeting different water types or species, these top 5 Wyoming rivers this week offer something for every angler.
- Focus on mid-day hatches when temperatures are warmest

For a new trip, verify the approach and current information separately.
Treat the river rankings, temperatures, flow readings and fly suggestions in this report as a record of its original publication week. A favorable rating from that week does not describe conditions on a later visit. Compare the dated observations with the current report for the same river section before making a new plan. Check the observation time as well as the value; a historical flow reading cannot confirm today’s water level.
Choose a specific destination before checking access. A river name can cover multiple reaches with different owners, entry routes and fishing rules. Start with information from the responsible land manager for the exact place you intend to visit. Confirm where entry and parking are permitted, whether a route crosses private property, and whether any closures or restrictions apply. A mapped ownership boundary or a roadside space alone does not answer those questions.
Use the app’s available map layers and river information as planning references, then confirm the details with current agency information and posted signs. Download any supported offline maps before leaving service, and remember that downloaded information reflects the data available at the time. Keep an alternative destination in mind if your planned entry is closed, unavailable or unsuitable when you arrive.
