Prairie Canada Pond Numbers

Prairie Canada Pond Numbers

Conditions across the Canadian prairies were greatly improved relative to last year. Building on excellent conditions from 2010 in portions of southern Alberta, Saskatchewan and Manitoba, the area of excellent conditions in the prairies expanded in 2011, including a region along the Alberta and Saskatchewan border that had been poor for the last two years. The 2011 estimate of ponds in Prairie Canada was 4.9 ± 0.2 million. This was 31% above last year's estimate (3.7 ± 0.2 million) and 43% above the 1961-2010 average (3.4 ± 0.03 million). As expected, residual water from summer 2010 precipitation remained in the parklands and the majority of the area was classified as good. Fair to poor conditions, however, were observed in the parklands of Alberta.
