The Winterhaven property is an 820-acre working ranch located in northeast Colorado along the South Platte River. The property was purchased by Ducks Unlimited in 2009 to protect conservation values and restore waterfowl habitat.
Blue Mountain Environmental Consulting prepared the original conservation easement baseline report for the 6,575-acre property in 2011 and returned in 2015 to inventory a newly added parcel and to determine if there had been any changes to the original acreage.
