The South Lake Tahoe Monitoring Project, a volunteer water quality monitoring effort coordinated by the Sierra Nevada Alliance, tested pollution levels in creeks and rivers. 2008 was the first field season for the group of trained citizen-monitors. Volunteers checked for polluted water in local creeks and rivers by collecting data which evaluates the health of water bodies in the Upper Truckee Watershed. Using meters, chemical tests and streamside habitat surveys, monitors gathered information on the ecological health of the river or creek.
