Cooling rivers set up a fall bite for CT smallmouth
Water is cooling into the low 60s across inland Connecticut, which is the shift that matters this week. USGS gauge 01193050 reads 60°F at 19,600 cfs, gauge 01194500 reads 59°F at 52.5 cfs, gauge 01194796 reads 61°F, and gauge 01184000 reads 60°F at 7,010 cfs. Those temperatures typically push smallmouth bass out of summer holding water and toward slower, deeper edges where they feed up ahead of winter. Tactical Bassin (blog) this week highlights fall bass patterns. One piece covers fishing a paddle tail on an underspin when bass are chasing baitfish, and another covers shallow jigs, soft jerkbaits and topwater for October bass.

Expect water temperatures to keep drifting down through the weekend if nights stay cool. The 59 to 61°F readings sit in the range where smallmouth typically stay active through midday, so you don't need to be on the water at first light. Late morning into mid-afternoon, when the sun warms the shallows a degree or two, is a sensible window to plan around.
Flow differs a lot by river. The large main-stem gauges (01193050 at 19,600 cfs and 01184000 at 7,010 cfs) are carrying a lot of water, so work slack pockets, inside bends and eddy seams instead of the main current. Gauge 01194500 at 52.5 cfs and gauge 01193500 at 140 cfs point to far gentler flow on the smaller water, where wading and casting are easier.
The First Quarter moon puts moderate light overnight, and many anglers find the hours around moonset and dusk useful. Check state regulations and any seasonal closures before you harvest anything.
Context
Mid-October is the heart of the fall transition for Connecticut freshwater. Summer weed beds are dying back, baitfish gather, and gamefish typically shift toward remaining green cover, current breaks and deeper structure. Fishing the Midwest notes the same pattern, that surviving green weeds often hold fish as others fade. Temperatures near 60°F are on schedule for this point in the season.
