30-day movement

What has Clear Lake been doing?

There is not enough historical sensor data available right now to summarize the last 30 days.

Lake levels can respond to rainfall, watershed inflow, dam and hydropower operations, seasonal target elevations, evaporation and downstream release requirements. This page reports what the matched sensor measured; it does not infer why an operator changed a reservoir.
