Projects>O’Dell Wetlands Monitoring
The O’Dell Creek Mitigation Wetland is located in historic ranching country in Madison County, Montana. Confluence’s wetland scientists are overseeing monitoring functions to meet U.S. Army Corps of Engineers requirements.
The O’Dell Creek Headwaters mitigation wetland is a component of a larger restoration project within the O’Dell Creek headwaters located on the Granger Ranch south of Ennis, Montana. The goal of the restoration project is to rehabilitate wetlands and channels of O’Dell Creek to natural channel dimensions, form, and function. During the 1950’s, the headwaters of O’Dell Creek had been ditched and channeled, effectively draining the riparian areas. Multiple phases of this project have been completed resulting in over six miles of stream restoration/creation and 100 acres of wetland enhancement/restoration. Confluence’s role has been to monitor the creation of mitigation wetlands to compensate for wetland losses associated with twelve Section 404 permits issued by the U.S. Army Corps of Engineers. Confluence wetland staff have completed surveying and mapping of vegetation communities, soils, and hydrologic monitoring throughout the several hundred acre project area in accordance with Army Corps of Engineers mitigation monitoring requirements.
