Here’s the latest version of my 4-Panel plot thru Water Year (Oct-Sep) of 2021 of the Colorado River big reservoirs, natural flows, precipitation, and temperature. Data (PRISM) goes back or 1906 (or 1935 for reservoirs.)
Above graph from Brad Udall, drawing on his work with Jonathan Overpeck. Colorado River flows over decades show concerning trends.
One thought on “Colorado River Flow Trends are Ominous”
Crikey! The current volume of both reservoirs is approaching the 1950s volume of Lake Mead alone. Think of the major population difference across those sixty years.
