The Medina Watershed, located in northern Utah, covers an area of approximately 255 square miles. The hydrology of the watershed is primarily mountainous, with steep slopes and narrow valleys. The watershed receives significant snowfall during the winter months, which contributes to the surface water flow during the spring and summer. The snowpack in the watershed is typically deep and persistent, with an average snow water equivalent of 30-40 inches. The watershed is home to several reservoirs that are used for irrigation, recreation, and municipal water supply. The constituents of these reservoirs include sediment, nutrients, and dissolved solids. The climate in the watershed is considered semi-arid, with hot summers and cold winters. Trends in the watershed include decreasing snowpack and increasing temperatures, which have implications for water availability and ecosystem health.
