Brook floater mussel
A brook floater filter feeding as it is anchored into the sediment of a stream bottom. Habitat loss is a long-recognized problem for many endangered species, and the brook floater is no exception. In-stream alterations that change flow and alter sediment loads can affect downstream locations where freshwater mussels live.

Comparison of recent photos of water in Halema‘uma‘u
These four images show the change in the area and level of water at the bottom of Halema‘uma‘u spanning August 9 to 13. Rocks in the center of the pond and near the shoreline help show the change in the waterline.
