One of my work accounts is a large pond with a very shallow gradient. There are bluegill (or possibly green sunfish; I cant tell the difference without getting them out of the water) nests everywhere! Here's a short vid of some and a pic. I thought it was neat to see It was really bright out, so it was hard to get a really good angle, but enjoy nonetheless!
