North Fork Moreau River #7 (AES D005) pool #3 looking upstream Figure 43. North Fork Moreau River #1 (AES D005) pool #2 looking upstream Location: Accessed from Rt 85 bridge and proceeded upstream to the first set of pools. Nearest Town: Redig, Harding County, SD Ecoregion: Northwestern Great Plains Aquatic Ecological System Type: D005-Northwestern Great Plains Intermittent Stream Key Environmental Factors: Hydrology—upstream dams or diversions in the watershed; Grazing— moderate impacts Rare or Unique Species: No rare species or communities documented Rare Features: No rare features documented Introduced/Exotic Species: Smooth brome was documented Overall Ecological Site Condition: Fair Reach Summary: The 300 m reach contained 4 pools averaging 10-15m long and wide and lacked connectivity. The first 3 proceeding upstream were deep enough to allow seining for fish, the last pool was clear and shallow enough to visibly inspect for fish and amphibians. Spacing between the pools was -20m apart for the bottom 3, and -100m from pool 3 to 4. All substrate of the pools was silt and fine sediments (<2mm) and pools 1 and 2 contained Typha latifolia stands with surrounding vegetation 42.
