Landsat-Based Water Quality Monitoring of Pyramid Lake

Abstract:Pyramid Lake Paiute Tribe (PLPT) in cooperation with federal, state and local entities has been able to increase stream flow, establish water quality standards and improve fish habitat in the Truckee River, a primary source of water for pyramid Lake. In the past, pyramid Lake water quality has been affected adversely by noxious blooms of Nodularia (a blue-green alge). Nodularia fixes nitrogen from air and Truckee River inputs, and decomposition of the Nodularia is considered the primary source of total nitrogen to pyramid Lake. Blooms can occur in all parts of the pyramid lake from August to early November. Temporal Landsat imagery has been investigated as a tool for monitoring the abundance of Nodularia in pyramid Lake. Increases in Nodularia abundance have been associated with increases in near-infrared reflectance measure from Landsat (MSS). Temporal database of Landsat near-infrared reflectance has been used to monitor changes in Nodularia abundance and outbreaks. Results suggest that temporal Landsat MSS near-infrared reflectance data are effective for monitoring Nodularia dynamics.
