Tamolitch Pool (also known as Blue Pool) is the basin of Tamolitch Falls, once a natural waterfall on the McKenzie River that has since been diverted by EWEB, buried by lava flows, and is now a “dry” waterfall. What remains is a large, breathtaking pool of spring-fed water that shades from deep purple to turquoise. This pool in its deepest sections are between 30 - 50 feet (10 - 16m).
