Dinger E. 2009. Integrated Aquatic Community and Water Quality Monitoring of Monitoring of Mountain Ponds and Lakes in the in the Klamath Network – Annual Report: 2008 results from pilot project in Lassen Volcanic National Park
In 2008, the Klamath Inventory and Monitoring Network, with assistance from the USGS FRESC field station, initiated a pilot project of lake and pond monitoring protocols in ecosystems of Lassen Volcanic National Park. The purpose of the pilot project was to field test draft standard operating protocol methods, for evaluation of suitability, feasibility, and to derive estimates of variation for power analyses. This report serves as a model for the format and content of Annual Reports that will be produced from the final implementation of the protocol. A total of 25 sites were visited in 2008 from 10 September to 16 October, including 4 sites that were deemed unsuitable for sampling. The methods from the draft protocol were largely successful, with few problems encountered. Adjustments made to the protocol were: (1) increasing the amount of water collected for water samples; and (2) refined the filter choice for Chlorophyll a analysis. Based on various Trophic State Indices, the lakes of Lassen Volcanic National Park are mostly oligotrophic, although there are also many mesotrophic lakes as well. A minority of lakes are eutrophic. A total of 16,415 zooplankton were identified from Lassen Volcanic National Park, from 68 total taxa. Species richness was estimated theortically at 184 total taxa. A total of 12,507 macroinvertebrates were identified, from 104 total taxa. The species richness was estimated at 140 total taxa. Fish were only identified at two lakes (9.5% of the lakes sampled). Summit Lake contained Brook Trout (Salvelinus fontinalis) and Reflection Lake contained Golden Shiner (Notemigonus crysoleucas). An outbreak of ranavirus inflicting Long-toed salamanders (Ambystoma macrodactylum) was observed at Cliff Lake. More than 30 individuals in the metamorph lifestage were seen either moribund or dead. Diagnosis of ranavirus was confirmed by the USGS National Wildlife Health Center.
