The North Fork Humboldt watershed covers an area of approximately 3,500 square miles in northeastern Nevada. The region is characterized by a semi-arid climate and is dependent on snowmelt for its water supply. The snowpack in the watershed is highly variable and can range from less than 50% of average to more than 150% of average. The region is also highly susceptible to drought, which can have significant impacts on surface water availability. Surface water in the region is dominated by the Humboldt River, which flows through the center of the watershed. The river is used for irrigation and supports a variety of fish and wildlife species. Several reservoirs are located within the watershed, including Rye Patch Reservoir and Wild Horse Reservoir. These reservoirs are used for water storage and recreation. In recent years, the region has experienced increasing temperatures and decreasing precipitation, which could have significant impacts on the watershed's hydrology and water supply.
