GIS Habitat Survey Dataset

About the datasets

ODFW Aquatic Inventories Project stream survey data available in GIS format


GIS Datasets  Each zipped file will contain both of these datasets and metadata

Reach Dataset
Our Reach Dataset summarizes habitat unit level information and gives an overview of the conditions within the reach or section of stream.  It should be a reference point for later comparative work or for the analysis of stream conditions.
Habitat Unit Dataset
The Habitat Unit dataset includes all of the unit data for the entire survey.  It is within this dataset that the most noticeable annual change will occur.  There will be changes in the distribution, size and location of habitat types annually.  This dataset is not intended to be a map of the absolute distribution of habitat types.  Rather, it indicates the condition of the stream at the time of the survey.


GIS Data Acquisition

In order to make our data easily available to both public and private groups, we have attached our information to a map of Oregon based on 5th field HUC's (Hydrologic Units).  To help in locating yourself, we have set up the 5th field hucs based on general portions of the state.  Click on the portion of the state that you are interested in (NW, SW, NE, SE) and you will be linked to the 5th field huc map for that area.
