What is the Idaho NRCS snow survey program?
The Idaho NRCS Snow Survey Program provides mountain snowpack and precipitation information via SNOpack TELemetry (SNOTEL) network in order to issue streamflow forecasts for Idaho. Common applications of snow survey products include water supply management, flood control, climate modeling, recreation, and conservation planning.
What is snowpack water equivalent?
Snow Water Equivalent (SWE) is a common snowpack measurement. It is the amount of water contained within the snowpack. Maps are posted weekly from mid-December through March or early April.
What is the difference between snow water equal to and precipitation?
The SNOW WATER EQUIVALENT represents the depth of water in the snowpack, if the snowpack were melted, expressed in inches. The WATER YEAR-TO-DATE-PRECIPITATION represents total precipitation since October 1st, expressed in inches.
What is the water year-to-date-precipitation?
The WATER YEAR-TO-DATE-PRECIPITATION represents total precipitation since October 1st, expressed in inches. Contact your state water supply staff for assistance.
What is the water equivalent of snow?
There is a general rule of thumb that says the perfectly typical snowfall will have a snow-to-liquid ratio of 10 to 1, meaning that 10 inches/cm of snow will yield one inch/cm of water.
What is Idaho snowpack?
What does this mean? It means that all of the snowmelt we could have captured in our reservoirs from a good snowpack earlier in the season isn’t there. We didn’t have the precipitation needed during the winter season to fatten up the reservoirs before irrigation season began in the valley.
How do you calculate snow to water?
Commonly, the percentage of water to snow is called the “snow ratio”. An old rule of thumb was that for every 10 inches of snow, there would be 1 inch of water (10:1).
How is the snowpack in northern Idaho?
Its average annual snowfall is 350 inches. Silver Mountain Resort reported 215 inches of snow at the summit, and 197 at the base, this winter. Average annual snowfall is more than 300 inches.
Is Idaho in a drought 2022?
The pattern of frequent precipitation in southern and central Idaho continues into June, further helping alleviate drought conditions. After a record dry period the first three months of 2022, April and May had wetter and cooler conditions.
Is there a drought in Idaho?
The U.S. Drought Monitor is updated every Thursday. It will be interesting to see if much changes this week. Currently, 57% of the state is experiencing “Severe Drought” conditions (D2-D4), with nearly 7% of the state under “Extreme Drought” conditions (D3-D4).
How much water is in 12 inches of snow?
For instance, for 12 inches of snowfall at a temperature of 16 °F, all you need to do is divide the amount of snow in inches by the snow coefficient, which in this case is 20. The result is 0.6 inches of rain.
How much snow does it take to make 1 gallon of water?
Say you’re using a one gallon container. One gallon (US measure) of water weighs approximately 8.3 pounds. If the snow in your one gallon container weighs four pounds then the water content of the snow is almost 50 percent which means it will take two gallons of snow to make one gallon of water.
How much water is in a square foot of snow?
The water content of any given cubic foot of snow can strongly influence how much the snow actually weighs. 1 cubic foot of water weighs 62.4 lbs. One cubic foot of snow usually weighs 5% to 32% of that. In the Midwest, the water content of a cubic foot of snow averages about 20%, or 12.48 pounds.
What is Utah’s current snowpack?
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 the weather like in Idaho year round?
In Boise, the summers are short, hot, dry, and mostly clear and the winters are very cold, snowy, and partly cloudy. Over the course of the year, the temperature typically varies from 24°F to 93°F and is rarely below 10°F or above 101°F.
What is snow water equivalent?
The snow water equivalent (SWE) or water content of the snowpack, is the amount of water in the snowpack measured in inches if you were to melt the snowpack. One could isolate a column of snow, melt it, and weigh it to determine the weight over that area.
Who published ground and roof snow load for Idaho?
Additional information can be obtained by contacting your local NRCS office, or in 1986, the University of Idaho, Department of Civil Engineering, published Ground and Roof Snow Loads for Idaho , by Ronald L. Sack and Azim Sheikh-Taheri.
What is roof snow load?
Roof snow loads can vary depending upon melting and re-freezing of snow and ice, roof slope, type of roof, aspect, drifting, etc. Building codes vary depending on the elevation zone and amount of snow and precipitation that falls. Building codes may also vary depending upon the codes in effect when the structure was built.
