Snow Surveys have been conducted at the Shirley Skinner Conservation Area (Kaibuskong River subwatershed) since winter 2006-2007.

In more recent years, NBMCA has conducted additional surveys on the 8th and 23rd of March and April to prepare for spring freshet. More data is needed to report normal conditions for these supplemental survey dates.

Key Terms
Spring freshet – the annual high water event resulting from rapid melting of snow and spring rains. Locally, this is usually between April and May.
Normal range – historic measurements have been within this range 50 % of the time, with 25% of historic observations recorded as higher and lower than these values. It is used to describe expected conditions, limiting the influence of individual extreme high or low values.
Snow water equivalent (SWE) - the amount of water stored in the snowpack and reported as the depth of water that would cover the ground if it were in a liquid state.
Well Above Normal – this measurement compares to the highest 10% of historic measurements.
Well Below Normal – this measurement compares to the lowest 10% of historic measurements.
