Weekly AI Outlook as of 06/05/26
Natchaug's running low at 17 cfs but still fishable, with caddis activity driving the best action through June. Hot afternoons ahead (87°F Thursday) will push trout deep, making early mornings and evenings critical. Focus pocket water and undercut banks with caddis patterns — Elk Hair Caddis and X-Caddis in #14-16 are your go-to flies. The low, clear water demands stealth and longer leaders.
- Flow: 17 cfs — manageable but demanding precise presentation in clear, low conditions
- Hatches: Peak caddis month continues with evening emergences; Elk Hair Caddis #14-16 essential
- Water Temp: Hot afternoons pushing 87°F will stress trout — fish early/late when temps drop
- Best Window: Dawn until 9am, then 7pm onward as heat stress peaks midday through weekend

About this Water
- Freestone
- Best months: Apr–Oct, peak May–June
The Natchaug River in eastern Connecticut runs through Natchaug State Forest — a small freestone river supporting stocked and holdover trout with wild brook trout in tributaries. The river is intimate, requiring close-quarters casts and short drifts through pocket water and small pools. Hatch activity is reliable through spring and early summer; terrestrial fishing produces through August.
The Natchaug runs through Natchaug State Forest — Connecticut's third-largest state forest — providing one of the state's largest contiguous protected trout watersheds.
