VASSAR, Kan. - The U.S. Army Corps of Engineers at Pomona Lake announce the permanent closure of 110 Mile Campground effective May 1, 2018. Due to underutilization and projected budget restrictions, the camping area, equestrian area, and nature trail will close in an effort to improve other park operating efficiencies and provide quality recreation opportunities for the public. The day-use boat ramp facility at 110 Mile Park will remain open with no operational changes.
