The Economics of Hydrometric Data Quality

Data about water quantity and water quality are fundamental to some of the most important decisions made by engineers and in choices made by societies. Abundance and quality of water are critical factors in many aspects of our economy, our environment, and our social and physical well-being. It is the case than multiple water resources objectives must be simultaneously managed. The costs of sub-optimal water resources choices can be substantial. Uncertainty is antagonistic to optimization. Read More


Game Changers – Continuous Water Quality Monitoring

Surrounded by hydrologists on a day-to-day basis, I most certainly talk about discharge and rating curves a lot. I find discussions about hydrometrics fascinating (actually I find any discussions about water and data management inspiring, but that is a whole other issue). But alas, I’m a self-professed “Water Quality Nerd” and a Water Quality Professional by trade. Read More


Hidden Data – The Ownership Gap in Hydrometry

A globally diverse group of hydrometric practitioners is forming for an open discussion around the question of hidden hydrometric data. If you would like to be part of this conversation please sign up on the post ‘Closing the Gap in Hydrometric Data.’


Closing the Gap in Hydrometric Data – A Call for Your Participation

How long is the tail of hydrometry? A solution for the gap between data availability and the impacts of water variability, across all scales of interest, on people and the environment is needed. One of my great hopes for the development of OGC standards for interoperable hydrometric data is that it will shed light on the dark data under the long tail of hydrometry. It is my opinion, unsubstantiated by quantitative surveys, that there are far more hydrometric data out there than are readily accessible from the major hydrometric data providers.

A Hydrologist’s Holiday

A 3-day hike in July on the Wapta Icefield in the Canadian Rockies with my son took us up the Bow Glacier, briefly onto the Yoho Glacier and then down the Peyto Glacier. Bow Glacier meltwater flows into the South Saskatchewan River (146,100 km2). Yoho Glacier meltwater flows into the Columbia River (668,000 km2). Peyto Glacier meltwater flows in the North Saskatchewan River (122,800 km2). Read More
