Sawhill Ponds is the home to many different kinds of waterfowl, fish, birds of prey, amphibians and reptiles. During spring and fall, the ponds provide a stop-over for migrating ducks.
The 18 ponds at Sawhill are the result of a gravel mining operation and reclamation project. Boulder Creek, now at the northwestern boundary of the ponds, has traversed the entire area in the geologic past. This ancient floodplain laid down great quantities of sand and gravel, and these deposits were mined for several decades until the early 1970s. When the mining ceased, groundwater filled the pits resulting in a wetland area that provides marvelous habitat for many species of wildlife. The ponds are stocked by Colorado Parks & Wildlife, and warm water fishing is a popular activity.
