156 rivers begin in Colorado. “The Mother of All Rivers” supplies 17 states and parts of Mexico with life-giving water. Our water begins in the Rockies, flows down rivers, pools in reservoirs, and has been bought, sold, fished, boated, measured and fought over since pioneers and engineers built the first diversions and ditches in the 1800s. Flow through history and down the Cache la Poudre River from Northern Colorado to the Mexican Land Grant where Ben Eaton learned how to bring water from the river to grow crops and cities in The Great American Desert.
