Item Cook County Soil and Water Conservation District Biological Sampling for the Poplar River Quality Assurance Project Plan(University of Minnesota Duluth, 2007) Breneman, Dan; Brady, Valerie; Johnson, Lucinda BBenthic macroinvertebrate and habitat sampling evaluations will be conducted at locations chosen to represent the most common instream and riparian conditions. A best effort was made to minimize bias from either direct or indirect landscape alterations when selecting sampling locations. Sampling sites outlined below (see Bl. Study Design) are proposed based on several parameters (e.g., biological, geomorphological, etc.), but logistical considerations including best available access will influence site selection. Sampling protocols will follow standard operating procedures outlined by the NRRI-UMD Microscopy Laboratory standard operating procedures for field collection, laboratory sample processing, and data analysis (NRRI/TR-1999/37). All procedures outlined in the NRRI document are subject to change to respond to MPCA guidance and field conditions.Item Poplar River Macroinvertebrate and Habitat Survey(University of Minnesota Duluth, 2008) Brady, ValerieWe surveyed the biota and stream habitat of the lower mainstem of the Poplar River in August 2007 to obtain baseline information on stream assemblages as part of a TMDL (total maximum daily load) study for turbidity. Four sites were selected along the Poplar River within the last 3 km before it enters Lake Superior. Data collected included macroinvertebrate community composition, in-stream habitat structure and stream bottom substrate types, and sediment particle size distribution. Poplar River data generated from each sample site were compared to data from 24 other North Shore stream sites to better place the Poplar River’s condition into a regional context.
