The Clark Fork River at Milltown Dam Restoration Project is located at the confluence of the Clark Fork and Blackfoot Rivers, east of Missoula, Montana. In 1908 a flood of record occurred on the Clark Fork River that deposited tailings from upstream mining and smelting operations along 150 miles of river and resulted in the accumulation of six million cubic yards of contaminated sediments behind Milltown Dam. Between 2008 and 2012, the site underwent extensive remediation and restoration, including removal of the dam, excavation of contaminated sediments, and reconstruction of over three miles of river channel and 250 acres of floodplain. Spatial data and GIS analyses have been used extensively over the course of the project, from restoration design, through implementation, and in post-project monitoring and evaluation. This presentation will focus on the ways in which these data are currently being used to provide information on the condition of the restored site as long-term monitoring of the project continues. GIS data and analytical tools supplement field-based monitoring efforts, providing quantitative and qualitative assessments of site conditions. These data are used to identify ongoing site maintenance needs, and help determine whether geomorphological and revegetation restoration treatments are trending toward the project goal of restoring a natural, functioning riparian ecosystem at the site.
