The Marsh Wren Community Wetland Area is located just north of Lincoln, NE, near the confluence of Salt Creek and Little Salt Creek. TFG was hired by LPSNRD to restore and enhance the hydrological features of the site to promote diverse wetland habitats including saline and fresh water wetlands.
Initial site assessment work by TFG and project partners included:
- Monitoring well installation and groundwater sampling
- Shallow soil conductivity data collection
- Plant community maps and plot data collection
- Deep well installation and groundwater testing
Project components included:
- Sediment Removal
- Sediment trap construction
- Low head embankments for hydrology management control
- Water level control structures
- Pedestrial access trail
- Overlook pier with viewing scope
- Low water manager vehicle access
- Saline groundwater pumping and distribution system
A very unique component to the project was TFG’s design of saline groundwater pumping and distribution system. Saline groundwater is pumped from about 150 feet below the wetland surface and distributed through gate irrigation pipe. The approach has been very successful at restoring saline wetland habitat.
