a. Its consideration of environment impact (such as accommodation for fish) became a model for future dam projects on western rivers

Explanation:

The Columbia River project was a project of great significance for the whole region, especially for the state of Washington. This project had many positive impacts such as production of electricity, irrigation for more than half of the farmlands, development of the area, opening up new jobs. One very big problem though was the impact on the species of fish in the river. As most of them are migratory species, with the building of the dam they were stopped in their movement, thus they became restricted to the upper part of the river. Also, the water and composition of the water changed, and all of these things contributed to significant reduction of the populations of the native species of fish.
