A small amount of snow over the winter, coupled with last year’s drought in the Okanagan Valley, means even farmers may have to operate under water restrictions this coming season.
Last year, water to some valley orchards was shut off because growers used more than their allotment of water before the end of the growing season.
In the South East Kelowna Irrigation District the main reservoir, McCulloch Lake, didn’t fill last spring. Users began to draw it down even earlier than usual because of record dry June weather.
Water users in the district are all on meters, including the irrigation connections. The district meters out water on an allotment, based on the parcel size, crop and soil type.
Early last year, growers were warned that supplies were low. They were told that to conserve water, each allotment would be reduced by 20 per cent.
The allotment system began in 2001. In 2003, a metered rate was instituted and penalties were added for users who exceeded their allotment. That included the ultimate penalty of having their water cut off.
“It’s a community water system,” South East Kelowna Irrigation District manager Toby Pike says. “Everyone gets their fair share. Otherwise they’re taking someone else’s water.
“Because of the Agricultural Land Reserve, prices for water are reasonable, but no one has a right to abuse the system,” he adds.
However, there were complaints from some growers that lack of sufficient water prior to the apple harvest could have serious consequences on the quality of the crop and the health of the trees.
Without a snowpack that is 24 per cent higher than normal this year, water managers forecast that reservoirs for the valley’s water utilities likely won’t fill again this year. So far, this year’s snowpack is below last year’s level in many parts of the watershed. And more than 80 per cent of the winter’s snow has already accumulated.
In addition, most of the lower-elevation snow melted earlier than usual. That means the actual water which will flow off higher elevations during runoff this year is expected to be less than normal.
Denise MacDonald, chair of the B.C. Fruit Growers’ Association’s water and environment committee, has warned growers that drought management plans will have to be prepared for every watershed in the Okanagan and Similkameen Valleys. She advises growers to make sure they are part of that process.
“Last year’s extremely dry summer, following on a winter when many reservoirs, including Okanagan Lake, didn’t fill, was a warning to everyone,” she says.
The water resource has to be managed on a sustainable basis, by not drawing down storage supplies beyond what can be refilled each year.
“It’s critical that we prepare before a drought situation is in full swing,” MacDonald says.
