Currently available: Unprocessed benthic macroinvertebrate samples from the D13 West St. Louis (WLOU) site in Colorado.
Benthic macroinvertebrate sampling in wadeable streams occurs three times per year at each site, roughly spring, summer, and autumn. Samples are collected in wadeable streams during periods of stable stream flow (e.g., when the stream is not flooding, defined as >3x median discharge for the preceding year) using a standard benthic sampler, depending on habitat and substratum type.
