Oregon, United States [HydroWorld.com] PPL Montana has selected engineering firm GEI Consultants to provide ecological engineering services for the construction of a US$7million full-height fish ladder at the Thompson Falls hydroelectric project in Thompson Falls, Montana, GEI reported.
The fishway, designed to provide over-dam passage for bull trout, is the first of its kind in the United States, the engineering firm said.
The project was developed with a number of governmental agencies and other entities.
Construction of the Thompson Falls fish passage ladder will allow migratory fish to swim upstream of a dam on the Clark Fork River in Thompson Falls for the first time in nearly 100 years.
The project began in July 2009 and is slated for completion in the summer of 2010.
