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. The URLs here are set to display the last 31 days of data.

These are selected from a larger list here.

Compare variations in flow at different points on a stream, on the same day. For example, look at the levels of the Olentangy just below the Delaware dam, and compare against the levels at Worthington (at I-270) to see the effects of stormwater spikes from the heavily developed corridor between Columbus and Delaware.
