Location: Latitude N:40.08621
Longitude W: 119.72099
Elevation: 4264 ft.
Virginia Range; Washoe County, NV
Equipment: 1). A YSI 6920 multiparameter WQ monitoring instrument is used to record temperature, specific conductivity, pH, dissolved oxygen, salinity, tds, and turbidity during the sampling event.
2). A 18"x12" kicknet, 500 micron mesh, is used to collect benthic macroinvertebrates at 3 sites.
3). A densiometer is used to obtain an estimate of canopy cover (%) along the 150 meter reach.
Period of Record: 2002, 2004 to present

Physical Habitat & Bioassessment monitoring began in 2002 on the lower portion of Big Canyon creek. Physical Habitat & Bioassessments are conducted annually during the month of April or May, depending on flows. Physical Habitat assessments are conducted within a 150 meter reach of the river. Water samples, stream measurements, and benthic macroinvertebrates are collected at the mid point of the reach following protocols in the Tribe's 2007 Quality Assurance Project Plan.(7.4 Mb PDF file)
