Central Platte River Instream Flow Study
Client: Central Platte Natural Resources District
Location: Grand Island, Nebraska
The objective of this study was to determine appropriate approach and implement an instream flow study for 60 miles of Central Platte River from approximately Chapman to Columbus, Nebraska. This study consisted of two phases. Phase 1 was the determination of the appropriate approach. Phase 2 was implementation of the recommended approach to develop instream flow recommendations for the 60 mile study reach.
Noteworthy components of the project:
- Developed the approach to blend with the previous instream flow recommendations conducted in the 1980s and 1990s.
- Examined several types of instream flow techniques including: one-dimensional Physical Habitat Simulation (PHABSIM), two-dimensional PHABSIM, and a GIS based analytical approach.
- Implemented the field study of a one-dimensional PHABSIM .
- Conducted all field sampling within a three-month period.
- The results of this study confirmed the previous instream flow recommendations, which were an extension from upstream study areas to the Central Platte.
