Horsetooth and Carter Lake Reservoirs

Horsetooth and Carter Lake reservoirs are now in summer operations. With help from spring run-off, Carter is almost 100% full. Horsetooth is about 90% full and still rising.

CAST for Kids at Horsetooth

One of the best parts of the year is the CAST for Kids event at Horsetooth Reservoir. This year's event is Saturday, June 7. We are currently taking participant registrations!

If you would like to register your child for this fun and exciting event, please visit our CAST event website and click the big red button on the right hand side of the page that says "Participant Registration."

If you would like to be a boater volunteer, go to the same page and click "Boater Registration."

2013 marked our 17th annual event. Although it was a little windy, 26 children and their families joined us for CAST at Horsetooth and had a fabulous time catching fish, making friends, and enjoying a day outside.

Parents can find the 2013 CAST portraits on-line at:

Please feel free to download the picture of your child and print at home. The pictures are provided as 5x7 portraits so they fit easily into the CAST plaque.

CAST events are special days because approximately 100 volunteers come together to take differently-abled and disadvantaged kids out on the water for a fantastic day of fishing and fun. Local-area fishing clubs, most notably the Bass Anglers Sportsman's Society, donate their boats, time, and personal expertise to give everyone a decent chance at catching a fish. Participating families, volunteers, and BASS fishermen and women are joined by participating businesses who donate staff and supplies to make the day a great success.

If you, or someone you know, would be interested in participating in our annual CAST for Kids event, please contact Kara Lamb to register. Registration is open for children in kindergarten through high school.

To learn more about CAST, visit the web site. To learn more about our event, search "events" on the CAST page, or visit us on Facebook at "CAST at Horsetooth."

Project Operations

Horsetooth and Carter Lake reservoirs are both part of the Colorado-Big Thompson Project.

Before reaching Horsetooth and Carter, C-BT water comes under the Continental Divide via the Adams Tunnel. Once in Estes Park, it is used to generate hydro-electric power at the Marys and Estes power plants. From Estes, water can either be released down the Big Thompson Canyon, or continue through the C-BT's southern power arm, generating power at three more plants: Flatiron, Pole Hill and Big Thompson.

As it moves through the power system, C-BT also moves through four other reservoirs. Water levels are about average for this time of year at Lake Estes, Marys Lake, Pinewood, and Flatiron reservoirs.

For more information on Carter, Horsetooth and the CAST for Kids event at Horsetooth, please contact Kara Lamb.
