This procedure is repeated until 100 organisms have been selected, moving to the next randomly selected petri dish as required. The remaining sample materials are again sieved on a il=30 mesh screen, labeled, and archived in 95% ethanol. Macroinvertebrate specimens other than chironomids and oligochaetes are identified through examinations using a Wild M5A stereomicroscope equipped with fib

These samples were processed (sorting, identification, and data analysis) by David Stagliano at the Helena lab following DEQ protocols (MT DEQ 2005). Macroinvertebrates were identified to the lowest taxonomic level, imported into EDAS (Jessup 2006), and biological metrics were calculated from the data using the Montana Department of Environmental Quality's newest multimet

Methods Aquatic communities (fish and macroinvertebrates) and riparian areas were inventoried and assessed using a combination of Montana Fish, Wildlife and Parks (MFWP) (fish) and BLM / EPA (macroinvertebrates and habitat assessments) protocols and methodology. These methods replicated those used during our July 2005 site visits during river flows at 500 cfs (recorded at the USGS Moorhead Gaging Station). Reach lengths were set at a
