The Inventory and Monitoring Program of the National Park Service sampled the biotic and abiotic parameters of mountain ponds and lakes of the Klamath Network in three park units: Lassen Volcanic National Park, Crater Lake National Park, and Redwood National Park. Sampling of lentic habitats in these parks occurs every three years (2013, 2016, 2019, etc.). This was the second sample period for this protocol. The purpose of the Klamath Inventory and Monitoring Network Mountain Ponds and Lakes protocol is to determine status and trends of ecological condition in mountain ponds and lakes. This report serves to report the measured values. Included in the report are measurements of physical habitat, water chemistry and quality, and aquatic communities. In Lassen Volcanic National Park, a total of 30 probabilistically chosen ponds and lakes were visited along with a single judgment site (Lake Helen). Sampling occurred from 20 July 2016 to 31 August 2016. One of the 30 probabilistic ponds-lakes were found to be dry, for a total of 29 probabilistic ponds and lakes sampled. In Crater Lake National Park, six ponds outside the Crater Lake caldera were sampled from 13 September 2016 to 16 September 2016, excluding a single site that was inaccessible. Based on visits in prior years and the current visits, it was determined that this constitutes all the known perennial sampleable ponds outside the Crater Lake caldera. There are no judgment sites in Crater Lake National Park. In Redwood National Park, a single judgment site, Freshwater Lagoon, was sampled on 20 and 21 September 2016.
