Stretches of the river were realigned to optimum sinuosity, preventing future erosion. The entire river was deepened and narrowed to a third of its original width. 2000 structures were placed in the river diverting the velocity of the water away from the banks to the center of the stream Bank erosion was halted and sediment transport enhanced by this design. Thousands of willows were transplanted on riverbends to further stabilize the banks and provide shade to cool the water. Miles of unused historic parallel channels were reopened and water diverted to them, further enhancing the fishery. Dotted with small oxbow lakes, this spring-creek-like environment provides habitat for huge rainbow trout.
