Columbia River Basin Population Crosswalk Geodatabase and Online Interactive Mapping Application

Project Description

The Columbia Basin needs a crosswalk of fish populations/units (p/u), using data which has already been defined by each managing entity within the Basin. The crosswalk will be a first step in a unifying framework and will be built as a spatial database in which each manager’s fish p/u are defined by subwatersheds and displayed in an online interactive mapping application. Visualizing how similar, or different, fish managers define the attributes of population/units, and how they are geographically bound on the landscape is the first step toward any agreement of a single name and definition of a fish p/u. Whether collectively the Basin-wide managers ultimately agree, or agree to disagree, on the names and characteristics of fish p/u, the crosswalk spatial database and mapping application will allow managers to place themselves on the landscape within the geographic boundaries of their fish p/u and know that data collected by another manager under a different fish p/u name, or in another watershed, overlaps the boundaries of their fish p/u.

Updating the Crosswalk Tool - A Conversation

February 6, 2017 - 11:43am

It has been several years since the Columbia River Intertribal Fish Commission (CRITFC) Salmon and Steelhead Crosswalk Tool emerged to support the Coordinated Assessments Project and partners around the Northwest. The crosswalk tool's purpose is to provide online mapping along with a fish names query system to serve access to geographic and descriptive information on fish populations (pop/units) of salmon and steelhead as defined by state and federal agencies, tribes, and regional projects in the Columbia River Basin (CRB). In December 2016, PNAMP and CRITFC convened a meeting to review the tool and discuss potential updates and explorations of new uses and services (

The meeting included 29 participants from 15 different agencies concerned with the health of salmon, steelhead, and other resident fish populations in the Columbia River Basin. The notes from the meeting can be found here ( and also accessed through the events page in "See all documents related to this event". Participants also engaged in an online survey concerning the crosswalk tool elaborating on how they use the tool and what other tools they use to acquire similar information (

Online tools complete; final report available

The online interactive mapping tools for the Columbia River Basin salmon population crosswalk can be found at this website:

There are three ways to query and receive information on fish pop/units – Species Maps, HUC6 Maps, and a database query system that returns names for comparison. Use the Species Maps to view and compare the mapped areas of a particular pop/units based on HUC6 watersheds and data reported with each pop/units per species. Use the HUC6 Map to compare all the pop/units and species per manager that are found in each HUC6 watershed. This map also reports data for each pop/unit. Use the Database Names Query system to look up what pop/units share mapped areas (HUC6 watersheds). Several maps and the query tool can be opened at the same time in different tabs for comparing.

The mapping applications and their reports are designed to be simple and similar to common mapping applications on the web today. However, if needed, a user guide has been created to explain the tools and how to use them.

In addition, CRITFC staff have drafted a final report detailing the project process and results. You can find the report here:
