I've seen this in the Spring at Granby. You'll also sometimes also see an 'oil slick' (no different than fish schooled up in salt water) as well.

In the Spring the Kokanee and Rainbows will be flipping on the surface eating midge.

The Kokanee will jump during the spawn mostly in the mornings and evenings.
Columbine bay comes alive with jumpers right at dusk In October.
