AUTAUGA CREEK BENTHIC INVERTEBRATE COMMUNITY ASSESSMENT, 2009 Will S. Mooty USGS
Autauga Creek Benthic Invertebrate Study The creek is listed on the 2006 303(d) list for an impaired benthic invertebrate community. The listing is based on a single sample collected by ADEM in 1999. The Alabama River Basin group within the Clean Water Partnership partnered with USGS to resample.
Benthic Invertebrate Communities Invertebrate samples collected in June 2009. Samples were collected using ADEM protocols. Multiple habitats sampled at each of 3 sites Autauga Creek at County Rd. 10 Bridge Creek at County Rd. 10 Autauga Creek nr. U.S. Hwy 82 (original ADEM assessment site) Invertebrate identification by EcoAnalysts, Inc. in Moscow, ID.
Autauga Creek Synoptic Field Parameter Survey Field parameters collected at multiple sites in the watershed. Specific conductance Dissolved oxygen Temperature Turbidity pH Low flow and high flow periods.
