Larvae of nonbiting midgeflies, mayflies and caddisflies, and stonefly nymphs were highly tolerant to dissolved gas supersaturation in laboratory bioassays. However, most larvae and nymphs lost some buoyancy control and floated, which could indirectly cause death. The immature insects tested became buoyant when exposed to water containing large quantities of fine air bubbles, simulating conditions that occur in a stilling basin below a dam.
