Suitable Backwater Over-wintering Habitat

A predictive GIS model is being developed that uses morphometric characteristics to anticipate the likelihood of a backwater being suitable for over-wintering of fishes. Water depth is used both to determine physical space available and to determine water exchange rates that influence water temperature and dissolved oxygen levels. Below is an example of the output of the GIS model.  Principal investigator: Jim Rogala.
