Where do these Maine lake levels come from?
Each row is the gauge the agency that runs the lake publishes — the Corps of Engineers, the Bureau of Reclamation, the state water agency or the US Geological Survey, depending on the lake. Open a lake and its own page re-reads that gauge as the page loads, wherever the agency lets a browser do it.
