On March 26, 2015 EcoAnalysts’ CEO Gary Lester presented the results of a stream biomonitoring project to the Clearwater Basin Advisory Group
(www.deq.idaho.gov/regional-offices-issues/lewiston/clearwater-basin-advisory-group.aspx). The project, entitled “Benthic Invertebrate Response to Restoration Activities in Paradise Creek, Moscow, Idaho From 1994-2014,” evaluated the biological effects of a stream restoration project and wastewater treatment plant upgrades within the City of Moscow, Idaho. Restoration monitoring effectiveness is frequently a missing component of stream restoration projects; however, in this case there were enough benthic macroinvertebrate data in the city limits to be useful in evaluating both point source and nonpoint source improvements in the stream. The abstract of the presentation is below and a copy of the project report is available on our website.

Several stream restoration activities on Paradise Creek within the City of Moscow limits have taken place since the mid-1990’s. The Idaho DEQ Beneficial Use Reconnaissance Project (BURP) has performed biological monitoring at several sites in the study reach since 1994. A look at benthic invertebrate community condition showed some improvements in relation to physical habitat restoration activities within the city limits. Upgrades to the City of Moscow wastewater treatment plant resulted in notable changes in benthic invertebrate taxonomic composition, including a reduction in pollution tolerant taxa and establishment of some pollution sensitive taxa. This presentation will discuss the biological responses to restoration activities, as well as the applicability of using BURP data to evaluate the effectiveness of such actions.
