DESCRIPTION: Modern records of gaged flow for major rivers are limited to the last 120 years, at most. These records, which reflect average annual flows as well as periods of drought, have been used to allocate water resources and plan for future uses. Tree-ring based reconstructions of streamflow have been used to extend records back in time. The most well-known of these, for the Colorado River, showed that the period of flow used to allocate the basin's water supplies in the 1920s was one of the wettest period of flow in the past five centuries. Reconstructions of flow for other basins, such as the Sacramento River, have shown that drought much longer than any in the gage records have occurred over past centuries.
