TEG (The Environmental Group) is a 501c3 non-profit environmental organization in Colorado. Located in the foothills of the Front Range, spanning Jefferson, Gilpin and Boulder Counties, TEG works to protect the natural lands and resources of the region from environmental degradation.

We focus on creating discussion and on-the-ground actions for a livable Colorado, and we work with environmentally-minded citizens and groups statewide to preserve this magnificent state.

TEG is the core group coordinating action to deal with the proposed expansion of Gross Reservoir.
