2013 Southern District/ SER 303(d) impairment and stressor identification monitoring - SCR_10_CMP13B

Purpose

Rachel Sabre and Craig Helker will conduct 303(d) biological sampling for 4 waterbodies in SER. Sampling for macroinvertebrates will occur in Mid-October to November in 2013.

Objective

Per 2013 Watershed Management Competitive Project Workplanning Guidance, the proposed streams may be listed on the 2016 imparment list. A list was generated by identifying waters with a measure of poor biological condition from samples collected during Tier 1 monitoring efforts, but where the pollutant or stressor has not yet been identified or the biological impairment has not yet been confirmed with a second biological sampling event. These sites require additional monitoring to confirm the potential biological impairment and to identify the causative pollutant. The criteria used to select these sites were: 1) Tier 1 monitoring stations (from the random stratified sampling network) that were sampled during 2010-11 seasons, 2) M-IBI results indicating “poor” biological condition (score < 2.5), and 3) located on waters that are not already identified as impaired. SER has a total of 4 sites on this list. The sites that will be sampled are: Pebble Creek-10031953; Unnamed trib to the Fox River (WBIC- 5034248) -10031278; Unnamed trib to the Nippersink Creek (WBIC- 5041996) - 10031310; Unnamed trib to the Des Plaines River (WBIC-5041996) - 10031310.

Outcome

Monitoring results of these 4 sites will be available in SWIMS and a short written summary of the monitoring results will be prepared and uploaded.

Study Design

Macroinvertebrate data is attached.
