Fall brown trout and steelhead window opens as water cools
Early-season fall conditions are settling in across the Hudson Valley and Finger Lakes. Our USGS gauge readings show water temps of 59 to 61°F at gauges 01359139, 01354230 and 01357500, with gauge 01357500 running 2,210 cfs and gauge 01358000 at 5,770 cfs. That is cool enough to put coldwater species on the move. The NY DEC Fishing Line issue dated October 9th flags fall fishing opportunities across the state and a reminder that trout season regulations change on October 16, so check current DEC rules before you keep fish. Over in western New York, Brookdog Fishing Co. reports for 10/05 through 10/11 that the smallmouth bite was excellent despite wind, including some giant fish in rough conditions. Their earlier reports describe strong walleye and lake trout action and a bass bite that shifted as Lake Erie's temperature dropped. Those are Lake Erie and Niagara observations, so treat them as a regional signal for fall behavior rather than a Hudson Valley report.

What's next
Expect water temps to keep sliding through the 50s as nights lengthen, which is the trigger that typically turns on fall-run brown trout and steelhead in tributaries and pulls smallmouth toward deeper, slower water.
With a New Moon on the calendar, nights are dark and low-light windows at dawn and dusk should do the most work. Fish early and late, and slow your presentations as temperatures drop.
For smallmouth, Tactical Bassin points to jigs, soft jerkbaits and topwater around hard structure such as dock pilings, laydowns and rocks this time of year. Their finesse coverage also highlights tiny topwaters, swimbaits and small jigs on tougher days. Fishing the Midwest adds that living green weeds can hold fish as other cover dies off, a pattern worth checking on any weedy shoreline you fish.
For walleye, Fishing the Midwest describes a plain bottom-bouncer rig with a snell and nightcrawler as a reliable cool-water producer. Flow readings of 2,210 cfs at gauge 01357500 and 5,770 cfs at gauge 01358000 suggest moderate to healthy volume, so check for rain-driven rises before committing to wading.
If you are fishing trout water ahead of October 16, review the DEC regulation reminder in the Fishing Line first, since catch-and-release and tackle rules typically shift with the season.
Context
Mid-October is typically the heart of the fall transition for this region. Warm-season patterns have faded, weed beds are thinning, and baitfish tend to relocate as oxygen and cover change. Smallmouth commonly feed up ahead of winter, brown and brook trout move toward spawning gravel in cooler tributaries, and lake-run fish begin showing in feeder streams as flows and temperatures allow.
Water temps near 60°F put this season roughly on schedule for the Northeast, neither early nor late. Anglers who adapt to the cooling trend by slowing down, fishing deeper edges and focusing on dawn and dusk usually find the best of the year's fishing now through early November.
