Weather

For Craig, MT, the National Weather Service forecast says: Today: A slight chance of showers and thunderstorms after noon. Mostly sunny, with a high near 67. Southwest wind 5 to 10 mph. Chance of precipitation is 20%. Plan around wind, changing light, and any showers or storms rather than assuming a full-day dry fly window.

River Notes

The best starting point is water that matches the current gauge: inside seams, protected banks, riffle drop-offs, and slower buckets rather than the heaviest current. A stable trend is worth watching through the day; if the hydrograph turns sharply upward, clarity and wade safety can change before hatch timing does. Missing field values are left as Not reported rather than filled from guesswork.

Hatch Activity

Current hatch guidance is based on seasonal May patterns for this river system, current public report context where available, and today’s official gauge/weather check.

Tactics

Start with nymphs in defined lanes and adjust weight, depth, or leader length before changing flies. If fish begin rising, simplify to a single dry or dry with an emerger/dropper and lengthen the leader. In bright or windy periods, return to subsurface presentations along protected banks and broken water. Re-check the gauge before wading new crossings, especially if the trend changes from stable or falling to rising.
