Summary
Fish data was integrated within a GIS by georeferencing observations to an existing national spatial framework (National Hydrography Dataset), which allows for broader transferability to watersheds shared with neighboring states, creating a seamless layer not limited by state boundaries. Addressing the management and conservation challenges for native fishes will require the ability to “data mine” the extensive existing information on distribution and abundance of species available from aquatic survey programs. Results from such syntheses can be used to assess the current conservation status of native fishes, quantify the extent of species invasions, and establish baseline distributions with which to evaluate the effects of climate change and other forms of environmental degradation.

Purpose
Fish survey and stocking data linked to stream reaches and lakes GIS data in the Little Colorado River Basin that can be used to assess the current conservation status of native fishes, quantify the extent of species invasions, and establish baseline distributions with which to evaluate the effects of climate change and other forms of environmental degradation.
