Data are from biological and physical environmental assessments conducted during 2018 in the lower Rouge River, MI. Sites were located upstream, downstream, and within the concrete channel section of the lower Rouge River. Water quality parameters, riparian zone characteristics, reptiles and amphibians, fishes, invertebrates, and river channel characteristics (water depth, flow, velocity) were assessed during 2018 from June-October. Previously established standardized sampling methods were used during all assessments.
These data contain counts of fish species collected with a 1.83 m x 9.14 m bag seine constructed of 1.6 mm Delta nylon mesh. When permitted, five consecutive 15.25 m hauls were made parallel to the shoreline. Sites with smaller shorelines were sampled to the greatest extent possible and distance recorded. The seine was pulled in the upstream direction to allow the net to stay open during sampling. Following each haul, fish were sorted by species and counted. Macrophyte community characteristics (percent cover and species) were assessed by visually approximating the proportion of sites occupied by each species. A rake was used to collect vegetation for lab verification of species identification. Other habitat features...
