Animas River Wetlands, LLC is creating a wetland project to provide another viable option to comply with the federal goal of "no net loss" of wetlands. Our wetlands is located in southwest Colorado on the Animas River. To talk about the project, please call 970-759-5585 or email us.

We provide both wetland and steam mitigation credits. A credit is a unit of trade used to offset loss of either wetland and steams in waters of the US.

The Animas River Wetlands project will satisfy two primary goals: 
To provide an off-site alternative for the mitigation of wetlands that have been adversely impacted; and to expand and enhance the natural wetlands in the Animas River watershed while conserving and protecting the lands forever.


In Colorado, only 3% of the land is wetlands; however, 90% of Colorado's wildlife depends on the 3%. Off-site mitigation is often preferred because the success rate of more significant, concentrated wetland projects is usually better than small, isolated on-site efforts. Additionally, because Animas River Wetland Bank will be ready before the need for mitigation, our area will avoid the temporal loss of wetlands for wildlife.

The number of birds we have seen in the wetlands has increased from 26 to 120 in 12 years. We have beavers enjoying our wetlands and cutting down some cottonwoods.

Experts often call wetlands, "nature's kidneys" for how they collect, filter and purify water.

The approximate 65-acre project is located just North of Durango on the Waterfall Ranch property owned by Patti Zink. The ranch has been in the Zink family since 1917- over 100 years.

willows The project will be constructed in 13 phases on terraced
acreage adjacent to the Animas River and includes the
development of five categories of wetland habitat: 
aquatic, marsh, wet meadows, willow, and cottonwood. 
These habitats combine to provide shelter, food, and
migration routes for hundreds of species of birds and
mammals. The protection of these habitats has been
identified as a top priority for residents and government
officials charged with protecting the diverse natural
resources of La Plata County.

This wetlands mitigation site has the oversight of an Interagency Review Team. The team members include the Army Corp of Engineers with representatives from La Plata County, US Fish and Wildlife, Colorado Division of Wildlife, Environment Protection Agency and Natural Resource Conservation Service.

Targeted grading of the created wetlands will be suitable for the establishment of aquatic, marsh, wet meadows, willow, and cottonwood habitats.  This stratification of aquatic habitats creates a broad spectrum of niches to facilitate wetland plant species diversity and habitat utilization by wildlife within the mitigation site.

The establishment, use, operation and maintenance of the wetland bank will be carried out in accordance with the following authorities:
