Vancouver’s vanished streams and waterways can be discovered once again thanks to a digitization project involving UBC Library and the Vancouver Aquarium Marine Science Centre.
UBC Library digitized the content of the Aquarium’s paper maps from the 1970s, allowing both scholars and the public to see the paths of old streams and the original shoreline of Vancouver. The digitized maps encompass the City of Vancouver, and show the large area of land reclaimed since the 1880s due to the city’s ongoing development over the years. Indeed, downtown Vancouver, now covered in pavement, used to be full of streams.

“Streams play an important role in the water cycle – instrumental to groundwater recharge, and corridors for fish and wildlife migration – and it is vital that we capture their historical data,” says John Nightingale, President and CEO, Vancouver Aquarium. “UBC Library has provided a great service by digitizing the Vancouver Aquarium’s original maps. This valuable data on the city’s natural history will be useful to current and future scientists as they investigate the city’s natural evolution for planning purposes.”
The original paper maps are heavily used by UBC’s Dept. of Geography. Concerns about the extreme wear of the maps, and subsequent loss of valuable historical data, led to the effort to preserve them in a durable digital format that allows users to explore Vancouver’s origins. Even though they may no longer be flowing, the old streams still have relevance to fisheries experts, ecologists (most of the streams were salmon and trout habitats) – and even those who wonder why their local soccer field is always damp.
Paul Lesack of UBC Library’s Humanities and Social Sciences Division used geographic information systems (GIS) software and traditional illustration software to transform the old maps into a multi-platform electronic offering.
An attractive and colourful PDF map is available for printing. The information can also be easily loaded into Google Earth with a double click, and overlaid on satellite and terrain imagery. For those who want to look at Vancouver’s aquatic history on the go, it can be used in specialized GIS applications or loaded into the appropriate iPhone app.
