Follow Poindexter Slough for flow alerts

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.

Follow this water

Signed in: one step. Otherwise we email a confirmation link first. Every alert has one-click links to stop it.

A water page organises discovery. It does not assert public access, legal access, current fish presence, guide availability or fishing conditions.

Flows, gauge statistics and flood stages come from USGS and the National Weather Service when the page is shown. Regulations, stocking, species and season statements link to the agency that publishes them; this page copies only the species names and the quoted sentences. Guide and shop listings come from the Legendary directories. Position: a point on the mapped channel of “Poindexter Slough”, halfway along its length in Montana, from the USGS high-resolution hydrography (NHDPlus HR), read 5 Nov 2026. It marks the water, not a particular access or reach. Water type is our own classification.
