Experts warn B.C. needs to better track water use amid drought

Growing up on a ranch in the Columbia River Valley, water has always been part of Kat Hartwig's life, and over the years, she's noticed changes.

Marshy areas her family used for irrigation or watering cattle are dry, wetlands are becoming "crunchy" rather than spongy underfoot, and snowmeltisdisappearing more quickly each spring, ushering in the dry summer months, Hartwig says.

Climate science supports her observations, showing that global heatingiscausing warmer temperatures and increasingly severe droughts in British Columbia.

Hartwig, who advocates for better water policy, and others saydroughtisexposing cracks in how the province manages water.

Officials don't alwaysknowwhoisusinggroundwater, how much they're using, orwherethey're drawing it from,expertssay. There are gaps in mapping and other data that officials need to effectively manage water during times of scarcity.

The provincedoesn'tkeep track of exact usage by mostgroundwaterlicence holders, the Ministry of Land, Water and Resource Stewardship confirmed. Rather, the licence sets the maximum amount of water each user can extract.

How long-term drought affects B.C. farms and fishing

As some parts of the province are still experiencing wintry weather, drought conditions persist, and it's changing the way British Columbians live, work and source their food and power. Two people in northern B.C. with a vested interest in groundwater levels tell us how they're managing.

That's the case for both domestic and some commercial users,including companies in the forestry, mining, and agricultural sectors, the ministry says.

At the same time, about two-thirds of pre-existing groundwater users have yet to even apply for licences sinceB.C. first began regulatinggroundwaterin 2016.

TheB.C. Energy Regulator publishes quarterly water-use reports for the oil and gas sector, and some other licensees may be required to report how much they use.Groundwaterusers may also be asked to complete a "beneficial use" declaration to show they're meeting licence terms.

But it's an incomplete picture of water use throughout the province at a time when signs point to deepeningdrought.

Hartwig,aswellasOliver Brandes, a water policy expert at the University of Victoria, and hydrogeologist Mike Wei, who retired from working for the province in 2018, sayB.C. lacks sufficient mapping and details ongroundwatersources.

B.C.'s Minister of Land, Water and Resource Stewardship, Nathan Cullen, saysdroughtwasn't always front of mind forB.C. governments and the public.

"If there were worries [about]water, historically, there was often too much, right?"

Cullen's ministry has been tasked with catching up to today's climate reality and delivering the province's watershed security strategy, expected sometime this year.

An intentions paper shows priority areas include enhancing monitoring and addressing data gaps.

TheB.C. First Nations Water Tableisco-developing the strategy, and Cullen says the provinceisworking to establish additional community-based groups this spring.

Many of those tables involve members of the agricultural sector, he says, pointing to the recent announcement of $80 million in additional funding for the province's agricultural water infrastructure program to help farmers weather times ofdrought.

"The scope and scale of the challengesisreal to my mind," Cullen says.

UBC prof emeritus says water metering can help us respond to B.C. droughts

Hans Schreier, a professor emeritus at the University of British Columbia's Faculty of Land and Food Systems, says water metering can be an effective response to increasing drought conditions and water demand in B.C.

But "standing up what may be dozens and dozens of these community water tables in short order ...isvery much in the government's interest," he says.

"This costs us one way or the other," the minister adds. "Better water managementisa lot cheaper than the management of crisis, similar to forest fire mitigation."

Asexecutive director of Living Lakes Canada, Hartwig works to build capacity for community-based water monitoring and fill the gaps in provincial data.

"We're also helping to educate and build a water-literate constituency, so people understand thatgroundwaterisa treasure and not to be wasted," she says.

There were just twogroundwaterobservation wells in the Columbia Basin when Living Lakes began monitoring in 2017, she says. Today, there are more than 30. Last year the group registered some of the lowest water levels in the last seven years.

In 2021, Living Lakes launched an open-access hub to bring water-related data from the Columbia region together in one place from sources including local governments, First Nations, community groups and the private sector.

But theexpertssay it's just scratching the surface of what's needed.

'Half a century of neglect'

B.C. has regulated surface water for more than a century, but before the Water Sustainability Act came into force in 2016, that wasn't the case forgroundwater, says Wei, who helped the province develop the legislation.

Before 2016, he says, landowners could drill next to a stream and pumpgroundwater, potentially depleting surface water, without provincial knowledge.

That's changing, but Wei saysB.C.is"dealing with half a century of neglect."

How can people in B.C. prepare for drought and wildfire season?

As spring arrives, B.C. officials are already warning of an early and "challenging" wildfire season. Assistant Prof. Andranne Doyon, director of the resource and environmental management planning program at SFU, tells BC Today guest host Dan Burritt that people need to think about protecting themselves and their neighbours well in advance.

He saysB.C. has mapped 1,200 aquifers with about 240 observation wells, most on the South Coast and in the southern Interior.

But much of the mappingis"rudimentary" and monitoring infrastructure inadequate, Wei says. It oftendoesn'ttell officials how much waterisbeing used, which direction it's flowing, and what the sustainable supply from an aquifer might be.

Cullen says he "always [wants]more data," and the provinceisexpanding monitoring sites.

B.C. has been working to bring people who usegroundwaterinto the licensing system introduced with the 2016 legislation. The province offered existing users a six-year transition period to obtain a licence with the date recognizing their first use of thegroundwater.

The dateiscrucial because licences showing newer usage are the first to be cut off during water scarcity under the "first in time, first in right" system, says Brandes,who leads the POLIS Water Sustainability Project at the University of Victoria.

Yet the province received just 7,700 applications from some 20,000 existing non-domestic users by the time the transition ended.

Those who didn't register may face a "rude awakening," Brandes says.

How extended drought has affected B.C.'s Gulf Islands

For the last 12 years, Rhonan Heitzmanns Saltspring Water Company has been pulling water from underground and distributing drinking water to more water-vulnerable areas on Salt Spring Island. Heitzmann tells CBC host Dan Burritt what hes noticed about water shortages on the island over the years.

"In a few places, thereisbasically not enough water," he says. "The people who ... weren't signed up in the transition period aregoingto be in a tough spot."

They can still apply for a licence moving forward, but it would no longer reflect when they first began usinggroundwater, Brandes says.

Cullen says sign-ups came in "dramatically" below what officials had hoped for and what the province needs to manage water.

"It's difficult to manage if you're not properly measuring," the minister says.

"We're trying to broadly understand the resistance to people getting licensed and to lower [it]," he says, adding things are "trending in the right direction."

"We're understanding the full actual nature of it in a much better way than we did, say, five years ago."

Fish protection orders issued

Brandes says the slow progress and general lack of "vital signs" about water inB.C. led to a "disaster" last summer, when critically low flows in several waterways prompted the province to issue fish protection orders that restricted the irrigation of forage crops in parts of the southern Interior.

The orders cut off several hundred surface andgroundwaterusers and some ranchers resorted to selling livestockasthey grappled with the shortage of feed.

Brandes says the province's handling of the situation contributed to uncertainty, social conflict, and a loss of public trust.

Wei, too, says the orders lacked transparency.

"People didn'tknowwhy they were being shut off. Science wasn't necessarily getting out there."

He says a lack of proactive investment in understanding water and building capacity to respond todroughtleads to "scrambling" in the face of urgent situations, and scramblingiscostly, financially and democratically.

"When you don't have information, it's not transparent, you erode public confidence in what you, the administrator for the resource, can do." he says.

"And when you start eroding it, you're eroding your democratic foundation."

The conversation in the Interior last summer "went badly," Cullen says, adding that restrictions are "the last thing" the government wants.

"Coming togetheristhe path forward, and that's what we're doing. That's why we're having those conversations in 20-plus communities already."

Hartwig says the work in the Columbia Basin servesasa template and underscores the importance of community-led water monitoring and governance.

The project has uncovered streams that were "over-allocated" with licences, she says,aswellasdry areaswheregovernment maps indicated high-elevation wetlands.

Yet she says three dozen community-based groups in the Columbia region have been forced to stop their work due to funding cuts in recent years.

"We have a huge amount of attrition of these small, volunteer-based water monitoring groups who are very concerned about their own watersheds," she says.

"We need those boots on the ground. We need that level of water literacy, and we need them to participate in civil society, right? We can't have that eroded.

"And that's not being fortified by the province."
