In 1991, the four lower Snake River dams (Lower Granite, Little Goose, Lower Monumental and Ice Harbor) together produced 8,201,426 Megawatt*hours or about 9.35% of the total FCRPS hydropower production.

Bold items are the Lower Snake River dams that are being considered for removal. Notice that the four combined provide nearly as much as the one John Day dam downstream on the much larger Columbia River.
