(North Bay, Ontario, March 24, 2020) Snow survey readings confirm that the snow is gradually melting. Snow depth has slightly decreased and water equivalence has slightly increased since the snow pack measurements taken on March 13 by the North Bay-Mattawa Conservation Authority as part of its flood forecasting program.
The average snow depth for the three sites is 35.3 cm, a 5.2 cm decrease from last week. The average water equivalence for the three sites is 121.3 mm, a 21.7 mm increase from last week.
NBMCA is now measuring the snow pack weekly, to monitor conditions during the spring freshet. This is a supplementary survey. The % normal will be available during the next snow survey which takes place April 1.
Snow is measured for depth and water equivalence at three locations in the watershed.
