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.
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.
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.
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.
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.
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.
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.
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, Carter Lake and Pinewood Reservoir 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.
Horsetooth Reservoir – 5,430 feet; Carter Lake – 5,760 feet; Flatiron Reservoir – 5,470 feet; Pinewood Reservoir – 6,580 feet; Hermit Park Open Space – 7,880 to 8,964 feet.
Due to the Bureau of Reclamation's security requirements, no recreation activity is allowed on any of the dams, or within 100 feet of any of the dams while on land.

Some campgrounds are closed during the colder seasons. However, most parks and open spaces are open year round. Seasonal closure of Red Mountain Open Space is December to March because of winter weather changes and the wildlife requirements as set forth in the Management Plan for Red Mountain Open Space. The Keyhole Trail at Devil's Backbone Open Space is closed approximately March to mid June for nesting raptors.
