Flathead at Snowmelt Peaks: Edge-Water Cutthroat the Key Play
USGS gauge 12372000 clocked the Flathead drainage at 14,900 cfs and 52°F just before dawn on May 7 — textbook peak-runoff territory for early May in northwest Montana. Main-stem wading is effectively off the table at those flows, and drift anglers need to read seams carefully. The productive water right now is the soft stuff: eddy lines, tributary confluences, and slower inside bends where cutthroat and whitefish can stack without burning constant energy against the current. On the lake side, Flathead Lake's surface is warming through the low-50s, historically a transition window that draws lake trout shallower before summer thermoclines lock in. One Montana-specific note worth your attention: Flylords Mag reported this week that PFAS chemical contamination has been detected in fish across several of the state's most popular fisheries, with Montana PBS also alleging that Montana FWP suppressed a 2024 internal report on the findings. No fisheries are currently closed, but anglers keeping fish should check for updated consumption advisories before harvesting.

Yellowstone caddis hatches building ahead of runoff
USGS gauge 06043500 clocked the Yellowstone River at 771 cfs on May 7 — a fishable pre-runoff reading that opens a productive window before snowmelt pushes flows into spring flood territory. Hatch Magazine, drawing on decades of Yellowstone hatch expertise, flags that caddis emergences are ramping up and deserve anglers' full attention right now. On the access side, MT FWP Fishing News reports that the boat ramp and parking area at Grey Bear Fishing Access Site on the Yellowstone remain closed due to ongoing construction delays, with completion now expected around May 21 — plan your float access accordingly and consult myfwp.mt.gov/fwpPub/allRestrictions before any float trip. One significant health note: MT FWP, alongside DEQ and DPHHS, has released PFAS fish consumption advisories for certain Montana waterbodies; consult the state advisory before keeping any catch. Nymphing and emerging caddis dry-fly presentations are the techniques to lean on while these moderate flows hold.
