Eagle Nest Lake State Park is a state park in New Mexico, United States. The park is located outside Eagle Nest, approximately 30 miles east of Taos. It was established on July 3, 2004. Its main attraction is a 2,400-acre lake which is popular for fishing and boating in the summer, and ice fishing and snowmobiling in the winter. The lake itself is a man-made reservoir created when the Cimarron River was impounded by the Eagle Nest Dam in 1918.
