2010 Map of Irishman Hill

About this map

Irishman Hill and Pilot Knob anchor this South Texas landscape, where the Balcones Escarpment's influence is seen in the intricate drainage patterns of the Sabinal River and East Elm Creek. The territory is defined by a ranching and water-management economy, evidenced by several private impoundments including Nunley Lake Number 1 Dam, Nunley Lake Number 2 Dam, and the Rehm Lake Dam. These small-scale water works are vital for sustaining agriculture in a region where seasonal creeks like Blanco Creek and Nolton Creek traverse the undulating terrain.
