Water was collected from soil lysimeters at key sites across Niwot Ridge and the Green Lakes Valley in the tundra and subalpine forest. Zero-tension soil lysimeters in the City of Boulder Watershed were deployed in the mid-1980’s. Additional zero-tension lysimeters were installed at Subnivean and Soddie sites in 1997. At c1 in 2010, 12 Tension lysimeters (Soil Moisture Equipment Corp Model 1900 Soil Water Sampler ) were installed at C1.SO, C1.ST and C1.SW sites, with four lysimeters at each site. In 2012, 15 additional zero tension lysimeters were installed in the City of Boulder Watershed at Gl5, Arikaree, and D1 locations (with 5 lysimeters at each site).
