The Colorado River connects us to 40 million people in the American West.
The Colorado River supports 40 million people as it flows through seven U.S. states and Mexico. The dark black line in the map below outlines the Colorado River watershed. Take a closer look and you will see that the largest cities in the west rely on water from the Colorado River, but are not necessarily in the watershed.
As an important headwater to the Colorado River, the Roaring Fork River contributes up to 12% of the annual flow of the Colorado River but the Roaring Fork Watershed is less than 0.5% of the Colorado River Basin land area. This statistic is illustrated well in the map below, where the Roaring Fork Watershed is outlined in pink, within the greater Colorado River Basin.
The Colorado River, riddled with history and majestic scenery, has many challenges as it flows through the arid west. One of those being that the Colorado River has not consistently reached the ocean in almost 50 years. But in 2014, a historic agreement between the United States and Mexico sent a pulse flow to the delta, mimicking spring flows which are the highest flows of the year, as snow in the high country melts. Dry stream beds once again ran with water, and dormant seeds started to bloom. The environmental and social impacts of this pulse flow are still being studied.
