Supersaturation of the Columbia and Snake River systems was caused by entrainment of air into water spilling over hydroelectric dams. Total gas saturations of 100% or more have occurred during the spring in each river system. External signs of gas bubble diseases were noted in adult Smallmouth bass and northern squawfish collected from the lower Snake and mid-Columbia rivers during 1975-76. Emboli occurred beneath membranes of the opercula body, and fins of 72% of the smallmouth bass and 84% of the northern squawfish. Hemorrhage was also noted on the caudal, anal, and pectoral fins of several fish.
