Snow is one of the most important sources of water in most parts of the world, which supplies about a third of the water needed for agricultural activities, drinking, and underground water sources. The runoff caused by melted snow can be destructive, also the numerous volume of snow can lead to an avalanche, so it's important to estimate it. The area of the snow research is around Goose Lake in California, the USA where the ground snow measuring station is (Latitude: 41.92999, Longitude: -120.4168117). The snow can be measured and calculated using the Daily Satellite imagery of the Landsat for five years' period (2017–2022) for about four months (December–March) (total of about 40 images. The information from ground snow measuring stations was used to evaluate the final results. The accuracy assessment shows 76% accuracy.
