How long has Milk River at Nashua, MT been measured?

Discharge records at USGS site 06174500 begin in 1939, about 87 years, covering roughly 9,200 days of published daily values. The long record is what makes the monthly percentiles on this page meaningful.

Is there a flow forecast for Milk River at Nashua, MT?

Yes. Rivermatics trains a machine-learned model — a temporal-fusion transformer — on this basin's observed flows, weather, and snowpack, and issues a daily flow outlook reaching 14 days ahead: a median estimate inside a confidence band, not a single number to bet on. A companion model forecasts each day's water-temperature high and low. Every forecast is scored against days the model never trained on, and that track record is published on the live gauge screen. Open live conditions to see the current outlook.

Where is Milk River at Nashua, MT?

Can I use Milk River at Nashua, MT data for flood or safety decisions?

No. Rivermatics provides estimates, not guarantees, and the readings and forecasts here may be delayed, inaccurate, or wrong. Do not use them for navigation or for any safety, rescue, or emergency decision. Check the National Weather Service and USGS directly, and use your own judgment.
