These are automated stream gauge stations reporting data to the Untied States Geological Survey. All stations report on stream depth; most report on flow volume and some include other measurements such as temperature. You can select graphic or tabular display. The URLs here are set to display the last 31 days of data.

These are selected from a larger list here.

Check these stations after a rain event. Compare variations in flow at different points on a stream, on the same day. Note the rates of rising and falling.
