The Mojave Desert Inventory and Monitoring Network (MOJN I&M) began pilot testing its Streams and Lakes protocol in the summer of 2009. The protocol was revised based on the results of the 2009 tests, and a full field season of monitoring was carried out in the summer of 2010. The field work was conducted primarily by the staff of Great Basin National Park (GRBA) and MOJN I&M cooperators. Discharge data on Lehman Creek was collected by the United States Geological Survey (USGS).
