METRO VANCOUVER -- With more hot weather records expected to be set this weekend, Metro Vancouver has extended water conservation measures for residential lawns and golf courses.

The biggest impact on Metro Vancouver residents will be on limiting lawn sprinkling to once a week. Even-numbered residential addresses may sprinkle laws from 4 a.m. to 9 a.m. on Monday; odd-numbered addresses can sprinkle from 4 a.m. to 9 a.m. on Thursday.

Golf courses can water fairways once a week.

Carol Mason, commissioner for Metro Vancouver, said the levels of the reservoirs at Seymour and Capilano are at 79 per cent, which is about where they usually are in early August.

"We have had a very unusually dry and hot May and June," she said Friday at a news conference at Metro Vancouver in Burnaby.

"We are experiencing record dry conditions and the combination of those weather conditions has resulted in a very high demand for water."

Metro's 23 member municipalities and political bodies are expected to fully implement the tougher water conservation measures by Monday.

Darrell Mussatto, chair of the Metro Vancouver Utilities Commission, asked members of the public to reduce their discretionary use of water.

Healthy lawns, he said, only need an hour a week of water. Not watering them at all means they go dormant and grow back in the fall when the rains return.

"My lawn is brown," he said at the news conference. "I don't water it at all. My car is not crystal clean. It's dirty. I do clean the windshield and license plates and mirrors so I can operate it safely, but I don't wash my car."

He said as part of conservation measures, Metro Vancouver is launching a water conservation campaign with the slogan Be Water Wise. It's Hot, It's Dry, Don't Waste a Drop.

Enforcement of water use is up to each municipality. In the City of North Vancouver where Mussatto is mayor, he said a bylaw enforcement officer will put a note on the door of anyone seen to be watering outside of the allowed times. If it happens a second time, the homeowner is sent a letter. The third time results in a fine.

Greg Moore, chair of the Metro Vancouver board of directors, said he hopes the public recognizes the need to conserve water because local government officials don't want to go around issuing tickets to people.

"We would rather people comply," he said.

He also hopes people can be educated that "there is a real need to conserve water" in the region.

June was the fourth driest June on record, said Matt MacDonald, meteorologist with Environment Canada. Last month, 11 mm of rain fell, compared to a normal June rainfall of 54 mm. The driest on record was in 1951 when 4.6 mm of rain fell.

June was also the second warmest on record, with mean temperatures of 17.9. The record was 1958 at 18 C.

MacDonald said the outlook is for more of the same hot, dry weather.
