In this website, Colorado River Streamflow: A Paleo Perspective, we will assess the gaged record of Colorado River streamflow in the context of multi-century flow reconstructions from tree rings. We will describe the Colorado River system and its management, then the century-long gaged record of flow, and then the use of tree rings to extend, or reconstruct, the gaged record 400 years or more into the past, providing a more complete picture of past flow variability. We will take a closer look at the most recent streamflow reconstructions for Lees Ferry, and how they compare with previous reconstructions.
