Many thanks to Bob Nichols, who documented the mussel die-off and subsequent alum treatment in 2010, and continues to video the goings-on in the Indian Ponds.

Alum floc falling through the water column and accumulating on the bottom sediment on the first day of the Mystic Lake alum treatment in September 2010.
A big smallmouth bass swims through the area about one hour after the alum treatment with some floc still falling in September 2010.
Descending through falling floc into the dark suspended sediment layer near the bottom at the deepest point in Mystic Lake, during the alum treatment in early October 2010. Surface light does not penetrate this layer so LEDs on the camera are turned on to illuminate the bottom.
