Description
High quality topographic surveying forms the foundation of RDG's river restoration projects. RDG's survey department provides the quality survey services that are necessary to accurately, efficiently, and cost-effectively evaluate existing site conditions, aid in project engineering design, and final construction staking.

RDG offers both traditional Land Survey (only in Montana & Idaho) and Hydrographic Survey services. Using both conventional and satellite based techniques, RDG's surveying capabilities complement RDG's other services by providing imagery, survey data, hydrologic data and base mapping for professional-quality final products.

RDG deploys Trimble GPS units and Topcon and Trimble total stations for collecting accurate precise data. Ground survey data are often integrated into LiDAR datasets to provide the level of detail necessary for producing accurate models and designs.

RDG has developed relationships with two partner firms to provide our clients with LIDAR, hydro-acoustic, and image acquisition services. These innovative techniques enable us to deliver high quality existing ground data for large scale restoration projects.

The use of large wood habitat structures and a variety of bioengineering techniques have increased the frequency and depth of pool habitats on the Jocko River. Important habitat components of Montana rivers, large wood, pools, and riparian vegetation function to diversify riverine ecosystems while providing recreational opportunities.
Restoration efforts re-established hydrologic connection with the Jocko River floodplain and re-activated disconnected meanders
Restoration efforts re-established hydrologic connection with the Jocko River floodplain and re-activated disconnected meanders. The restored channel plan form and connected side channels emulate the pre-disturbance condition of the Jocko River, improving habitat for bull trout and other aquatic species.
Historical impacts to the Jocko River channel and floodplain
Historical impacts to the Jocko River channel and floodplain resulted in impaired aquatic habitat conditions and loss of riparian and wetland functions.
