The Fisheries Information Summary System (FISS) is a Federal and Provincial geo-database that provides summary level, fish and fish habitat information for waterbodies throughout the province of British Columbia. Information is georeferenced using online digitizing tools and is linked to the BC 1:50,000 watershed atlas using a hierarchical watershed coding system. Using FME, a similar watershed atlas was created for the entire Yukon Territory at a fraction of the cost and time using the Horton Order transformer and other tools. The resulting intelligent hydrolgical network is now available for the Yukon through the Community Mapping Network at www.cmnbc.ca. We will describe some of the challenges encountered in the creation of the hydrological network and provide and overview of the new Yukon FISS system.

5. What is the Yukon Hydrological Network?

6. The Yukon hydrology project area
About 186,000 sq. Miles
35,000 people
264,000 rivers, 215,000 lakes
http://cmnmaps.ca/fiss_yukon/

7. What is the Yukon hydrological network?
! A GIS-based watershed atlas similar to the
British Columbia 1:50K Watershed Atlas;
! Fish and fish habitat management tool,
watershed modeling, land use planning and
regulation, and potentially climate change;
! It connects streams to its tributaries and
lakes from headwaters to the sea;
! Uses a hierarchical watershed code system

8. Building On Canada's National
Hydrographic Network Geospatial Data
! The NHN is the base hydrology for the
Yukon Watershed Atlas at a scale of
1:50,000;
! The NHN uses available federal and
provincial data;
! provides a quality geometric description and
a set of basic attributes describing Canada's
inland surface waters (initiated in 2002);

9. Canada's National Hydrographic Network
! Unique identifiers are associated with each
geometric and event object (NIDs)
! Geospatial digital data completed to the CL3 level
! GEOBASE.ca
! Network linear flows
! Validate flow direction
! Waterbody definitions (feature coding geographical
names)

10. Limitations of the National Hydrographic
Network
! The CL3 level of NHN data provides a basic
stream network for the Atlas project;
! Stream segments are topologically correct
and connected end to end;
! Stream direction is mostly correct;
! No attribution to allow the building of a full network;
! Stream segments do not have an identifier that
indicates which segments are part of the same
stream except where stream are named

11. Input Data - National Hydro Network
The National Hydro Network data produced by Natural
Resources Canada at Completion Level 3 was used as the
stream network input to this project.

13. Horton Order Stream Classification
The Horton Order was calculated for each stream network
defining the mainstem and tributaries using the
StreamOrderCalculator transformer in FME.
Horton Order assigns the smallest number to the highest
tributaries and the largest number to the mainstem of the
network.
Mainstem is the named stream if it exists or the longest path to
the pour point (destination) if a named stream does not exist.
Each stream was assigned a unique ID based on the connected
Horton Order segments.
Only Level Priority 1 stream segments were processed.

14. Creating Routes and Watershed Code’s
Arc Macro Language Scripts (AML’s) were adapted from the BC 1:50,000
Watershed Atlas project to build routes and assign hierarchical watershed codes:
YUKON_BUILD_ROUTES
Joins stream segments with a common ID together into continuous routes.
CREATE_NEW_YWS_CODES
Creates watershed codes based on the routes and seed watershed codes.
Watershed Code Example:
800-345678-00000-00000-0000-0000-000-000-000-000-000-000
Tributary of Yukon River flows into the Yukon River 34.5678% of the way upstream

15. Final Data Products

The 13 work units were merged together and Clipped to the border to create a final atlas product.

17. Next Steps
! Copy watershed codes to all point data
! Assign watershed codes to secondary
routes
! Create dynamic segments for point data
! Create watershed boundaries
! Fix stream and lake names and routes
! Learn more about using FME
