Groundwater discharge plays a critical role in maintenance of temperature and nutrient supply for salmon-bearing stream on the Kenai Peninsula. Effective management of these systems requires knowledge of the distribution and extent of groundwater recharge and discharge sites, but this information has largely been lacking in this remote region. We will be integrating diverse datasets with GIS tools to develop a predictive model to map likely locations of groundwater recharge and discharge sites. This effort will include ground-truthing as well as model development.
