Eightmile River is a freestone river in Connecticut. Connecticut has 2 waters named Eightmile River in the USGS Geographic Names Information System; this page is the stream whose mouth is in Lower Connecticut River Valley County, the one the agency list names.
Pick one of its USGS gauges and hear from us when the flow moves into or out of its usual range for the date, or crosses a flow you set. We check the public USGS reading every 2 hours and email only when it crosses, at most once every 6 hours. Flow alone is not a fishing forecast or a safety call.
Signed in: one step. Otherwise we email a confirmation link first. Every alert has one-click links to stop it.
Start from the agency's public access map. Nothing on this page grants or implies access: check the agency map, posted signs and landowner permission before you fish.

Each comes from the agency's own published list; where the list names a reach it is quoted. A designation applies to the listed reach, not necessarily the whole water. Listed in the finder under trout.

Normal for Nov 5: 5.28–28.7 ft³/s (middle half of 48 years of record). Now: 24 ft³/s, normal.
Normal for this date. 24 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 48 years of record: 10th 3.39, 25th 5.28, median 16.8, 75th 28.7, 90th 55.1 ft³/s.
Daily means on record for Nov 5: lowest 2.07 ft³/s, highest 529 ft³/s.
Classes as USGS labels them (hyswap: flow categories (WDFN_stats schema) (U.S. Geological Survey) ); percentiles from the USGS daily statistics (U.S. Geological Survey) (approved daily means; the reading is provisional and instantaneous).
Steady over 24 hours (+0% discharge). Rising or falling means a change of more than 10% in discharge (or 0.2 ft of gauge height) over 24 hours; our rule of thumb, not a USGS class.
The National Weather Service has no flood-stage gauge here, so no official flood category is shown.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. Connecticut DEEP publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Connecticut rule, with Connecticut DEEP's own figure added: 68°F.
This gauge is on our page for Eightmile River, but no agency page we read lists its species.
Turn Around Don't Drown. “A mere 6 inches of fast-moving flood water can knock over an adult.” No flow number makes a crossing safe; if in doubt, stay out.
Turn Around Don't Drown (National Weather Service)Guidance from the readings above and the published thresholds named with each line; not a fishing forecast, a safety guarantee or a statement about access. Local rules and closures come first.
Checked Nov 5, 2:12 PM EST; readings refresh at most every 15 minutes and statistics daily. Provisional USGS data can be revised. Conditions change: re-check before you go. This is general guidance, not a fishing forecast, a safety guarantee or a statement about access.
