A distinguished panel of glacier scientists was in Golden on Feb. 1 week to present information about the state of water reserves in the Columbia Basin, and to discuss the impacts of shrinking water supply.
Kindy Gosal, Director of Water and Environment for Columbia Basin Trust, said the evening was intended to be an information session for the citizens of the area about glacial recession.
“I think it’s important information to fill in the knowledge gap that people have in this basin about what’s going to happen for the future of water supply in the face of climate change and the recession of our glaciers,” said Gosal.
“The reason we need this information is because those glaciers are our banks and reserves of water. And really, we don’t have a good idea what’s happened to those bank accounts of water and what the future impacts might be as those bank accounts become depleted, or how fast we’re depleting their funds.”
Speaking at the event, Brian Menounos, from University of Northern British Columbia, commented on the potential political ramifications of this research. Part of this involves striking a balance between the electricity and water needs of the people in the Columbia Basin, southern British Columbia, and exports to the United States.
“One of the reasons we are studying these glaciers – and this is also why BC Hydro finds this interesting – people are going to consider the renegotiation of the Columbia Basin Treaty. When it was actually first set, at the turn of the last century, people assumed the glaciers were at their extent, that climate was more or less stable. We know that is not the case now. So we have to have a better understanding of how those glaciers have changed and how surface flows have changed.”

Whatcha gonna do when the well runs dry?

What are we going to do when our new well runs dry? Dig a deeper one. What are we going to do when that one runs dry? Drill deeper again and ask why the wells keep running dry.
The prairie moisture cycle has been disrupted. Nobody disputes that point. But how badly is it disrupted and can it be fixed? Nobody knows, says John Pomeroy, director at the Centre for Hydrology at the University of Saskatchewan. Prairie people know they have to go progressively deeper with their wells and as they do, the water is often lower quality than their previous well. “Most shallow surface aquifers once had very good quality water, but very little storage capacity,” said Pomeroy. Small storage limits the ability to recharge and available water is used quickly.
“These shallow aquifers are connected to the surface so they experience the same rain and drought cycles we experience. They get their water from the moisture cycle, which goes up and down, wet and dry.”
As the Prairies required more water for irrigation, livestock and municipal purposes, shallow wells ran dry and were abandoned in favour of deeper wells.
“There’s much more water underground than on the surface or in the shallow aquifers. Nobody knows how much,” Pomeroy said. “But the flow rate in the deep aquifers is extremely slow and it’s mostly very poor quality. There are a few areas with high quality deep water, such as the Assiniboine Delta Aquifer, but most deep water isn’t suitable for agriculture or people. A lot of that water was laid down in pre-glacial times, so it’s old. The older it is, the more dissolved solids it has. It can’t be used for anything.”
Pomeroy said it’s easy to see how shallow wells and their high quality water were pumped dry. The water was needed. But other land management factors affect the situation.
Recharging ground water on the Prairies is different from other places, Pomeroy said. Because these shallow aquifers are small, they recharge quickly from potholes and sloughs. Conversely, they also respond quick- ly to drought or having their recharge sources cut off. “Recharge absolutely depends on sloughs and potholes. You need water standing for a period of time to force it through that thick till layer. Sloughs are mainly filled by snow- melt runoff. Snow is the primary source of water for our prairie water tables. Summer rainfall that runs into the sloughs generally evaporates before it has a chance to recharge the water table.”
Pomeroy said a cool rainy summer will recharge some of the water tables but with 70 percent of prairie sloughs and potholes now drained, every remaining acre of surface water is vital. “Every time we drain another pot- hole, we lose one more source of snowmelt water for our shallow aquifers and recharge for those shal- lower wells. There’s another problem with the remaining sloughs. We’re not putting as much snowmelt runoff into those sloughs as we did 20 years ago.”
Farmers and researchers agree that water is the limiting factor on all types of agricultural production on the Prairies. With a limited amount of water most years, the industry has geared itself to maximum use of that precious resource.

On November 10th CBC radio’s “The Morning Edition” had an interview with Nicholas Kinar, a grad student at the Centre for Hydrology. You can listen to the interview here.
Sound waves used to study snow
A University of Saskatchewan graduate student has discovered how to use sound waves to determine the water content of snow — a finding that could help scientists better predict floods and droughts and shed light on climate change.
“Nicholas Kinar is the only person who has been able to figure out how to use sound waves to measure the amount of water in snow,” said his supervisor John Pomeroy, Canada Research chair in Water Resources and Climate Change and director of the U of- Centre for Hydrology.
“This will allow people to put improved water management systems in place and offer an early warning for water irrigation supply,” said Pomeroy, noting that 80 per cent of the water in Saskatchewan lakes and rivers comes from melted snow.
Going North to Help Gauge Global Water Supply
By Lisa Johnson, For The StarPhoenix, Saskatoon, SK
In the Sheep Creek Basin in Ivvavik National Park, in Canada’s far northwest corner, Stacey Dumanski took full advantage of the amazing 24-hour sunlight this summer to do fieldwork that could help improve global water prediction.
“We are entering a global water crisis, and given rapid climate change and resource development in the North, this work is urgent,” says the fourth-year University of Saskatchewan student.
Water shortages due to climate change could seriously affect Canadians and people all over the world. Dumanski’s research in the remote creek basin will help policy makers better understand water resources in cold regions and predict the global water supply.

In the News: Water Monitoring Network Flows
By Mari-Louise Rowley – Rocky Mountain Outlook
Plans for an integrated hydrometeorological observation and prediction network focused on western Canada’s watersheds moved closer to reality as more than 80 delegates attended an international conference at the Radisson Hotel and Conference Centre in Canmore earlier this week.
Running Dec. 8-10, the Improving Water Security Through Integrated Observation and Prediction Networks conference drew top glaciologists, hydrologists and utility and government representatives from the U.S., France and across Canada.
“We’re all drinking from the same tap – the tap being the Canadian Rockies,” said John Pomeroy, University of Saskatchewan-based Canadian research chair in water resources and climate change. “Our water doesn’t stop in western Canada.”
Water that originates in the Rockies, from North America’s hydrological apex at Mount Snow Dome on the Columbia Icefields, eventually flows to three oceans, the Atlantic, the Pacific and the Arctic, while water from Bow Lake, the headwaters of the Bow River, flows through Calgary and southern Alberta to eventually feed the South Saskatchewan River.
And the issues that are affecting the flows of fresh water all over the world – pollution threats from industry, overuse due to population growth and decreased flows due to the impacts of climate change – are equally pressing in western Canada, Pomeroy said. As such, establishing a network dedicated to collecting data, conducting research, and predicting future flows is an important undertaking, but a restricted one given the work currently underway.
