TRWMA members each appointed one representative who served on the 35 member Turkey River WMA Board of Directors, meeting quarterly as a full Board and more frequently in committees to review information, develop recommendations, and finalize plan components. Partner 2: TRWMA Committees. Dozens of public and private partners served on TRWMA committees considering research, best management practices, economics, social factors and discussing local lessons learned. This plan is a direct reflection of their input and recommendations and would not have been possible without them. A full description of the committees is included in the Local Leadership section of this plan. The committees included: Executive, Techical, Community, Commissioners, County Infrastructure, Producer Groups, Education, Emergency Management, Fisheries, and RCPP. Partner 3: Iowa Economic Development Authority. Administered HUD CDBG funding for the Turkey River WMA to develop this plan, including funding to contract professional facilitators, researchers and planners to help with development of this plan. They also administered HUD CDBG funding for the Iowa Flood Center and IIHR to model and test their models in the Turkey River Watershed and Otter Creek Watershed. Partner 4: Clayton County. Clayton County Board of Supervisors served as the applicant for the IEDA funds. They and the Clayton County Auditor provided fiscal leadership and accounting for the IEDA and other grants on behalf of the TRWMA. Partner 5: Iowa Flood Center. Provided state-of-the-art, in-depth analysis, research, and modeling that helped all the partners better understand the TRW and how specific actions could reduce flooding. They also provided equipment and monitoring throughout the TRW, and funding for specific projects in Otter Creek Watershed including five rain gauge/soil moisture probes, two stream gauging stations, and 3 real time nitrate monitors in Otter Creek Watershed. They have two additional nitrate monitors in the Turkey River and are partners in the placement and use of over 23 rain gauge/soil moisture
