Backwater effects
Backwaters (off-channel areas) of the UMRS are characterized by individual bodies of water often resembling lakes. These lakelike areas vary in size, shape, depth, and connection to the channels. As a result, these overall characteristics of a lake may greatly affect how the water body functions. In particular, LTRMP has focused research on how connectivity might affect conditions that are important to resource managers (i.e., winter water temperature).

Predicting backwater lake suitability using landscape metrics. The exchange of water between the channel and backwaters influences habitat conditions. The amount of water exchange should be somewhat predictable by morphometric characteristics that can be spatially mapped in a GIS. We found a couple simple metrics that partially explain suitability.
