These fish riverine records were organized in tables in 2014 using descriptions by collectors and georeferenced using GEOLocate an online web service. This dataset is part of the larger Managing Idaho’s Landscapes for Ecosystem Services (MILES) study, an NSF/EPSCoR funded project to understand the impact of climate change and urban growth on social and ecological systems and services in mid-sized cities in Idaho. This information will be used to develop distribution models for each species to gain a more complete picture of where fish are distributed within the Portneuf Drainage** and what environmental factors are influencing where fish occur.
