Is It A Wetland?

In most situations that involve potential impacts to wetlands, the U.S. Army Corps of Engineers, along with the U.S. Environmental Protection Agency, has legal authority under the federal Clean Water Act. The wetland program at the Colorado Parks and Wildlife does not have a role or any authority in these activities. Corps personnel determine:

  1. whether the area in question qualifies as a wetland under the Clean Water Act;

  2. whether the proposed impact or activity requires a permit; and

  3. if so, what type of permit is required, the extent of review, and the need for offsetting mitigation.*

There are three Corps districts in Colorado, so where the wetland is located determines which district to contact to resolve wetland issues. 

The three main offices are:

  1. Denver Regulatory Office – Omaha District (NE Colorado)
