GUIDANCE DOCUMENT: “Water Balance Approach on Vancouver Island” (#7 in the Watershed Case Profile Series, released January 2018)


The storyline is built around three regional Water Balance Methodology demonstration applications. “To be useful…the simulation model must be physically based and deterministic, and it must be designed to simulate the entire hydrological cycle…hence it must be a water balance model,” wrote Ray Linsley (1917-1990). He pioneered development of continuous hydrologic simulation as the foundation for water balance modelling. The Water Balance Methodology is a synthesis of watershed hydrology and stream dynamics.

“We also need to apply Watershed CPR to begin the process of moving the land and water back to health.” wrote Fin Donnelly. “A large-scale program to conserve, protect and restore the Fraser’s tributary riversheds would start with a change in attitude. Let’s work together to ensure the mighty Fraser River, one of the world’s greatest salmon rivers, stays mighty for generations to come.”

WATERSHED CASE PROFILE SERIES: Shelly Creek is the City of Parksville’s last fish-bearing stream! – Restore Watershed Hydrology, Prevent Stream Erosion, Ensure Fish Survival (October 2017)


“Shelly Creek is a tributary of the Englishman River, a major watershed system on the east coast of Vancouver Island. Shelly Creek is important to salmonids, and this is why it is necessary to understand what is causing the Shelly Creek stream channel to fill with sediment, as well as what can be done to ensure fish survival over time,” stated Peter Law. “In 1999 the Englishman River was first declared to be one of the most endangered rivers in BC.”

WATERSHED CASE PROFILE SERIES: Green Infrastructure Innovation in Langley Township – ‘Design with Nature’ to Create Liveable Neighbourhoods (October 2017)


“This Watershed Case Profile celebrates the ‘good work’ done by the Township of Langley. By showcasing and sharing the ‘story behind the story’ of green infrastructure innovation, our hope is that other communities will learn from Township experience,” wrote Kim Stephens. “Design with nature…a whole-system approach…learn by doing and adapt. These three phrases capture the essence of how the Township builds neighbourhoods.”

“The reality today is a very different work environment then what we ‘old guys’ grew up in,” stated Wally Wells. “That leads to a required dialogue of what communicating really means and how the message is received and interpreted by different generations. Maybe, just maybe, we take too much for granted based on what we individually know in trying to communicate asset management. We need to think very hard about the way we carry the message – with, I would suggest, more thought to the perception of the listener.”

ARTICLE: Blue Ecology – for humans to adapt to a changing climate, a new culture of water is necessary! (announcement in Asset Management BC Newsletter, September 2017)


“The warming of the planet’s atmosphere is causing water to move more quickly and disruptively through the global water cycle. Flood, drought, fire, wind and cold – extreme events are becoming the norm. Instabilities in the water cycle are increasingly apparent,” wrote Kim Stephens. “All one need do is reflect on what British Columbia has experienced in 2015, 2016 and 2017. Impacts are magnified by human interventions. “

“The Partnership for Water Sustainability is evolving online tools that support implementation of the whole-system, water balance approach. British Columbia, Washington State and California are leaders. We are moving forward in parallel on this journey,” stated Jim Dumont. “Real-world success would be defined as reduced stream erosion during wet weather, and sustained ‘environmental flows’ during dry weather.”

The Partnership for Water Sustainability provides a type of engagement and outreach with local government that provincial staff no longer provide. Collaboration with participating local governments creates sharing and cross-pollinating opportunities that help eliminate the ‘disconnect between information and implementation’,” wrote Kim Stephens. “A desired outcome is that land use and infrastructure practitioners would understand how natural systems support municipal services.”

“Many years ago, the province established a set of criteria which determined the level of drainage improvements that were deemed to be acceptable in terms of cost-benefit, and the ability to pay,” explains Ted van der Gulik. “The supporting analysis optimized the relationship between agricultural return on production and cost of drainage infrastructure investment. These have come to be known as ARDSA criteria. ”
