In 2021, 43 wetland pools were constructed at Oakwoods Nature Preserve (Hancock County, Ohio) with funding from the H2Ohio program to capture and sequester nutrient runoff before entering the Blanchard River (Maumee River/Lake Erie Watershed). Post-construction hydrologic analyses, however, indicated that the wetland pools do not intercept intermediate-sized flood events originating from a headwater stream draining the preserve. To improve floodwater capture during these spate events, the installation of a small weir has been proposed. The purpose of this study is to characterize the stream benthic community prior to weir installation. Thus, in fall 2025, macroinvertebrates, periphyton, fish, and physicochemical data were collected from riffle habitats upstream and downstream of the proposed weir location (10 total samples). These surveys will be repeated in spring 2026 to strengthen baseline characterization of benthic community structure and assess potential post-installation impacts in the future.
