- What areas does Larimer County Department of Natural Resources manage?
The Department manages a variety of reservoir parks, open spaces, and trails throughout Larimer County, from Estes Park to Loveland to Fort Collins to the northern County border. For detailed information, visit Parks, Reservoirs, Open Spaces, and Trails
- What are your prices?
For areas that require entrance permits
, you'll need a permit for each vehicle for each day or for each vehicle + boat trailer combination for each day. You can purchase daily permits, good from day of purchase to noon the following day, or you can purchase an annual entrance permit, valid for a physical year, month of purchase through month of purchase the following year. Annual entrance permits are transferable among vehicles registered to the same household.
Boats carried on or in a vehicle (e.g. kayaks, canoes) come in under the vehicle entrance permit. Vehicles with trailered watercraft come in under the vehicle + boat trailer combination permit. All permits are displayed in the vehicle passenger-side window.
To camp, you must buy a campsite in addition to the entrance permit. If you do not have a camping reservation, you must check in at specific locations in the parks. Check the signs at entrance stations.
- Where does the money go?
Revenue generated from permit sales goes directly back into your parks and open spaces to pay for operating expenses (for example: trash collection, restroom supplies, picnic tables, etc.) and personnel expenses (for example: rangers and maintenance staff out in the field).
Your Open Lands Program
operates on a quarter-cent sales and use tax. This money is used to protect open spaces, natural areas, wildlife habitats, regional parks, and trails.
- Why do the water levels fluctuate at Carter Lake, Flatiron Reservoir, Pinewood Reservoir, and Horsetooth Reservoir?
These are Bureau of Reclamation reservoirs used for water storage. In the winter the reservoirs are filled and in the summer they are drawn down when the farmers call for water. Cities use the water, too, for industry and drinking water.
- How deep is the water?
At Carter Lake, the average depth is 80 feet, with the deepest point being 180 feet. The deepest point in Horsetooth Reservoir is 212 feet.
- How big are the reservoirs?
Horsetooth Reservoir is 6.5 miles long and 1/2 mile wide with several coves. Carter Lake is 3 miles long and 1 mile wide, an oval. Pinewood Reservoir is 100 acres. Flatiron Reservoir is 47 acres. Mary's Lake across from the Estes Park Campground at Mary's Lake is 42 acres, and East Portal Reservoir by Estes Park Campground at East Portal is 2 acres.
- Where can we boat? Do I have to have my boat inspected for Aquatic Nuisance Species (ANS)?
You can boat at Carter Lake and Horsetooth Reservoir. Pinewood Reservoir has no-wake-speed boating--perfect for canoeing and belly boats. Flatiron Reservoir does NOT allow boats (this includes belly boats) due to rapidly fluctuating water levels. No boats are allowed at Mary's Lake or East Portal Reservoir.
There are vessel capacity limits on both Carter Lake and Horsetooth Reservoir. Those limits are often reached on weekends during the summer. At high water Carter Lake's maximum capacity is 187 boats. At high water, Horsetooth Reservoir's maximum capacity is 380.
Horsetooth Reservoir and Carter Lake require mandatory watercraft inspections for Aquatic Nuisance Species (ANS). This includes inspection of watercraft motors, trailers, compartments, and any other associated equipment or containers before launch or departure from high risk waters. The only exclusions to these inspections are: hand-launched rafts, kayaks, belly boats, float tubes, canoes, windsurfer boards, sail boards, or inner tubes.
