The Middle North Canadian Watershed (HUC 11100301) covers an area of approximately 26,278 square kilometers in central Oklahoma. The watershed is primarily drained by the North Canadian River and its tributaries. The hydrology of the watershed is influenced by the climate, which is characterized by hot summers, mild winters, and low precipitation. The watershed experiences occasional droughts, which can impact the water supply for surrounding communities. The snowpack in the watershed is generally low, with snowfall occurring primarily in the northern regions. The surface water is used for irrigation, recreation, and drinking water supply. Reservoirs within the watershed contain both natural and anthropogenic constituents, including sediment, nutrients, and pollutants. Over the past century, the region has experienced a warming trend, with increased frequency of extreme weather events such as heat waves and droughts.
