Active Living and Outdoor Recreation

For many Coloradans, what makes our state an attractive place to live are not only mountain peaks and beautiful scenery, but also the vast recreational opportunities, including Colorado-Big Thompson Project facilities. Approximately 2 million people visit the C-BT Project’s lakes and reservoirs each year to fish, boat, water ski, camp, hike and picnic. The C-BT Project offers year-round recreational opportunities for active people of all ages. 

While Northern Water doesn't manage the recreational opportunities at our reservoirs, we're thankful to our partnering agencies that manage recreation at C-BT Project water bodies on both sides of the Continental Divide. The C-BT Project is also an important economic component of Grand, Boulder and Larimer counties.
