River Name is the name of the river and the section. = Notify immediately if running. = Email notify if running. = You are in the River Network.

Class of the river gives an approximate difficulty. See the safety section of this website for more information on rapids and ratings.

Level gives the most updated gauge tied to a river. See the notes and comments for how to interpret the reading. Readings may be delayed, come from bad sources, or have other miscalculations. Additional detail on a gauge can be ascertained by a simple click to the level. Metrics for a given level are: CFS, Stage (ft), in/hr for rain, and r.c. meaning no direct flow, but 0.0-1.0 is boatable.
The astrix (*) indicates a comment on the flow, plus (+) indicates a good flow, tilde (~) indicates that this is a stand-in for the real flow, or the flow is delayed, an explination mark (!) indicates there is a warning associated with the flow.

Relative Level explains how low or high a reach is based on being above or below the recommended range. This column is used when color is not visible or obvious (mobile phones, or color blind people). The first letter is L,R, or H for Low, Runnable and High. The second number is 0-9 where 0 is bottom end and 9 is top end. Therefore, "R0" is low, "R5" is medium, "R9" is upper high. If you see a river that is "H0" and coming down, maybe it will run tomorrow. Sort the list by r.c. to find rivers that are in the ideal range in your area. Trend gives information on how quickly a level is rising or dropping using r₁-r₂/(t₁-t₂) using the last readings gathered. Readings may be spaced hours apart and may miss local spikes. Be careful when using these.

Last updated is specified in days then hours then minutes with "d","h", and "m" suffixing the respective amount. Use your best judgment on interpreting flow in a stream based on type, season, and drainage size to see if the flow might still be valid. Days will be left off for where they do not apply. A leading zero is left on for readability. = Warning left in last year. Click. = Visual gauge observation in last 2 days. Click. = Associated Event. Click.
