abstract
Throughout the United States, an increasing concern has been the availability and allocation of water. Much of the Southwest depends on river systems that are recharged annually in the Rocky Mountains and with increasing evidence for global climate change, which may produce large hydrologic shifts, there is an increasing need to understand the full range of previous hydrologic variability in order to make accurate predictions of future variability. Here evidence for past lake level changes shows severe aridity at the headwaters of the Snake-Columbia, Missouri-Mississippi, and Green-Colorado Rivers in the Rocky Mountains, as well as, at the headwaters of the North Platte River. In the first region, severe aridity existed between 9 ka (thousand years before CE 1950) and 3 ka, >11.3 ka, and 1.8-1.2 ka. In the head waters of the North Platte River, there was severe aridity during the Younger Dryas period, ~12.4 -11.3 ka, which may indicate a period when there was complete desiccation of the North Platte River.
