The Rye Patch Reservoir is a reservoir on the Humboldt River in the U.S. State of Nevada. It is located about 22 miles northeast of the town of Lovelock, and is managed by the Pershing County Water Conservation District. The reservoir stores water for the agricultural area surrounding Lovelock, which is at the far downstream reach of the Humboldt, near the Humboldt Sink. Since the Lovelock area receives a mere 5.76 inches of rain annually, agriculture requires irrigation, but the high variability of the Humboldt (which often runs completely dry) means that water storage is necessary for irrigation to be feasible.
