Dashed lines are forecast. Values are at the gauges; water takes hours to a couple of days to get from there to the lake. National Water Model via NOAA/NWS · public domain.

No lake effect is shown. Turning volume into feet needs today’s surface area, and this lake has no storage or surveyed-area reading to get it from. During floods, watch the main page instead.
