Canada1Water New Publication and Data Release Notice: National Digital Terrain Model (C1W-DTM) Dataset
What: The Canada1Water Digital Terrain Model (C1W-DTM) with lake bathymetry dataset has now been published in Data in Brief. The peer-reviewed article documents the methodology used to develop a harmonized national elevation dataset designed to support integrated hydrological modelling across Canada and transboundary watersheds. This work introduces a seamless 1-arc-second (~20 m) resolution elevation and bathymetric framework derived from multiple national and international DEM and lake bathymetry sources, standardized to support continental-scale groundwater–surface water modelling and applications such as HydroGeoSphere.
Canada1Water New Publication and Data Release Notice: Hydraulic Parameterized Integrated Soil, Bedrock and Peatland Dataset
Our Canada1Water soils dataset has now been published in Data in Brief. The peer-reviewed article documents the methodology used to develop national-scale soil, bedrock, and peatland datasets designed to support integrated hydrological modelling across Canada and transboundary watersheds. This work introduces a 250 m resolution, hydraulically-parameterized dataset integrating mineral soils, bedrock outcrops, and peatlands into a consistent framework for groundwater–surface water modelling and HydroGeoSphere applications.
Canada1Water Data Release Notice - Spatial Datasets of 30-Year (1991-2020) Average Monthly Total Precipitation and Minimum/Maximum Temperature for Canada and the United States.
Development of spatial datasets representing 30-year (1991–2020) average monthly total precipitation and minimum/maximum temperature for Canada and the United States. These high-resolution (~2 km) datasets were generated using observed climate data from Environment and Climate Change Canada (ECCC) and the National Oceanic and Atmospheric Administration (NOAA), interpolated with thin-plate spline models to produce seamless geospatial grids.
Canada1Water Data Release Notice - Heating degree day spatial datasets for Canada
Development of Heating Degree Day (HDD) spatial datasets for Canada, covering two 30-year periods (1951–1980 and 1981–2010). These datasets were generated using daily temperature observations from Environment and Climate Change Canada (ECCC) and interpolated using thin-plate spline models to create high-resolution geospatial grids (~2 km resolution).
Canada1Water - Machine-Learning Based Bias Correction of ERA5-Land and FLDAS Soil Temperatures Using SWE and NDVI
On May 26-29, 2024 - Tyler Herrington attended the Canadian Geophysical Union’s (CGU) annual conference to present his recent work titled 'Machine-Learning Based Bias Correction of ERA5-Land and FLDAS Soil Temperatures Using SWE and NDVI'.
Serving up a wealth of water data
Aquanty’s Graham Stonebridge took the opportunity of the December 2023 C1W progress meeting to share how the project’s web team is building a portal that can meet the full range of potential user needs.
Bringing the model to the masses
Delivering C1W data to the public demands a user-friendly web portal that’s built for a digitally savvy audience. Derek Steinmoeller, leader of the Aquanty team spearheading that effort, offers a preview of what’s in the works.

Canada1Water data framework: Harmonized national-scale hydrographic, soils, and hydrogeologic information to support groundwater and surface water analysis
Several members of the Canada1Water team attended the CWRA Annual Conference in Halifax last month. It was a really great opportunity to get out into the Canadian water resources community and introduce some of the work we’ve been doing. Eric Kessel delivered a poster presentation (see below) to highlight just a handful of the many datasets that are being produced as part of the project.
The Canada1Water ‘value add’ – datasets
Even before Canada1Water’s hydrologic simulation goes live, the project will deliver value to decisionmakers and researchers by making its datasets publicly available. Hydrogeologist Eric Kessel gives a preview of what’s to come, starting with a highly anticipated data product this summer.
A hydrologic time machine
Once it’s up and running, Canada1Water will allow users to track the evolution of groundwater and surface water flows backward and forward in time — from 1979 through to the year 2100. Dr. Steve Frey provides an overview of the modelling framework driving the Canada1Water project.
