What is snowpack and why is it important?
Snowpacks are an important water resource that feed streams and rivers as they melt. Therefore, snowpacks are both the drinking water source for many communities and a potential source of flooding (in case of sudden melting). Snowpacks also contribute mass to glaciers in their accumulation zone.
How is Utah’s snow pack?
Utah’s snowpack, as tracked by the Natural Resources Conservation Service, is well below the median in every basin in Utah except the area around Beaver. The overall number is approaching the levels at the same time in the disappointing 2021 water year. At the current rate of decline, 2022 will be behind 2021 by Feb.
How many different types of snow are there?
There are two variables that determine snow type, temperature and air moisture. Snow comes in five general types: graupel, plates, needles, columns, and dendrites. Each snow type forms in different temperatures and moisture levels.
What causes depth hoar?
Depth hoar forms when a shallow snowpack is exposed to an extended period of cold and clear weather. Large cup-shaped facets form and may reach 4-10 mm in size. These grains are cohensionless and have a hard time bonding due to their angled structure and large size.
How do I know if my snow pack is safe?
The first step in evaluating snowpack safety is to dig a snow pit. It is critically important that the pit be dug on a slope that is the same aspect and angle as the slope you intend to travel, while still being sure to not expose yourself to an avalanche if one were to trigger.
How is climate change affecting snow pack?
Temperature and precipitation are key factors affecting snowpack, which is the amount or thickness of snow that accumulates on the ground. In a warming climate, more precipitation will be expected to fall as rain rather than snow in most areas—reducing the extent and depth of snowpack.
Why is snowpack important in Utah?
“Our snowpack is very important,” Haskell said. “It’s about 95% of our water and we’re just under 12 inches of water in our snowpack.” She also said water levels are 16 inches during a typical year. With levels as low as they are, there is concern over the effect climate change had on the snowpack.
What is Utah’s current snowpack level?
The current snowpack is about 121% of the median, or 56% of what officials want to see for the whole year. Across the state, reservoirs are seeing lower-than-average capacity, with 35 of the largest 45 below 55%, according to the Utah Division of Water Resources.
What is a pile of snow called?
Noun. snowpile (plural snowpiles) A pile of snow.
Does snowpack affect drought?
Snowpack typically acts as a natural reservoir, providing water throughout the drier summer months. Lack of snowpack storage, or a shift in timing of snowmelt from that reservoir, can be a challenge for drought planning.
What is melted snow called?
Definition of snowmelt : runoff produced by melting snow.
Why is Utah not getting any snow?
Utah has had too many consecutive years with below-average water in its bank, and it’s running a deficit. The state has hardly seen a storm since Jan. 1. “Even though [current] snowpack is decent, we just haven’t continued to get the snow,” Hess said.
How is snowpack calculated?
Density for the snowpack is calculated by dividing the snow water equivalent by the depth of the snow. Density can be used to measure variability across the snowcourse and is also used to quality control the samples taken.
Is Utah in a drought 2022?
Dry soils reduce spring runoff effectiveness because the soils soak it up before it can reach reservoirs, streams, rivers and lakes. With 99.39% of the state experiencing severe drought or worse, Gov. on April 21, 2022, Spencer J.
