Ice fishing tournaments are monthly (Jan, Feb & Mar) through the winter; the spring No Name Tournament is usually the weekend after Mother's Day weekend and the fall pike event is usually the weekend after Labor Day weekend.

All fishing is prohibited in the restricted area near the dam on the east end of the reservoir. This area is marked by a closure buoy line that stretches across the lake at that point.
All fishing is flies and lures only and is catch and release within 100 feet of the mouth of the inlet. This area is clearly marked with a set of buoys positioned in the shape of a square around the mouth of the river.
Fishing from any island or from any dock is prohibited. Fishing is permitted everywhere else on the reservoir. Check our fishing closure map for full details of these areas.
Trout daily bag/possession limit is four fish, of which no more than two can be 16 inches or longer. - Northern pike has NO bag/possession limit.
- Kokanee salmon daily bag/possession limit is 10 fish at all times of the year, snagging is allowed east of the inlet buoy line, Oct. 1 - Dec. 31.
- Ice-fishing shelters must be portable.
- The use of live minnows is strictly prohibited.
- Fishing guides and outfitters who use the park for commercially guided fishing or recreation activities are required to purchase a special-use permit. Please contact the park office for more details at (719) 748-3401.

As many of Eleven Mile's salmon anglers have been aware, the salmon population has declined since 2006.
The DOW announced on Dec. 20, 2008 in a press release that the reason for the die-off can be laid at the hands of a small parasite known as gill lice (Salmincola sp.). The gill lice are responsible for a sizeable die-off of all age classes of salmon in Eleven Mile Reservoir.
Gill lice are not harmful to humans provided that fish are prepared properly (145 degree heat or until the flesh is opaque and Separates easily with a fork).
Trout have a higher resistance to the parasite and no loss of any of Eleven Mile's trout species has been observed. The salmon population has made slow gains since 2006, but continues to remain far below those levels.
The threat of Aquatic Invasive Species (AIS) is a very real threat that affects everybody. AIS species can destroy facilities, ecosystems and recreational equipment alike. It is in nobodies interest to allow their introduction into a "clean" reservoir.
Recently, Colorado Parks and Wildlife biologists confirmed the presence of two invasive species, New Zealand mud snails (NZMS) and a plant called Eurasian water milfoil (EWM) in Eleven Mile Reservoir. Spinney Mountain Reservoir is still "clean" as far as parks and wildlife officials know. NZMS primarily feed on algae and aquatic plants, and can crowd out other desired fish and invertebrate species. EWM is an aggressive aquatic plant that out competes native plants and can form large strands on the surface of the water, which can entangle motors and degrade the quality of recreational boating opportunities.
Colorado Parks and Wildlife will be conducting boat inspections on all trailered 
vessels that are intending to either be launched on or removed from the reservoir. Belly boats, canoes and kayaks without motors are still exempted if they do not arrive on a trailer. But, we need the help of every boater and fisherman that uses the reservoir. It is critical for the boating and fishing public to fully cooperate in order to protect boating and fishing opportunities not only at Eleven Mile Reservoir, but all water impoundments within Colorado and prevent the spread of these damaging organisms.
Mandatory inspections of all non-exempt vessels will be conducted at either boat ramp (when open for use) and must be completed satisfactorily prior to launching on the reservoir or exiting from the boat ramp parking lot. Any vessel, float tube or belly boat that is found to be contaminated will be refused admittance to the reservoir until that vessel, float tube or belly boat is satisfactorily decontaminated. Owner's of any vessel, float tube or belly boat found to be contaminated after being removed from Eleven Mile Reservoir will be assisted by parks and wildlife staff in ensuring that the vessel, float tube or belly boat is "clean" prior to exiting the boat ramp parking lot. It is illegal in Colorado to knowingly transport ANS.
Full decontamination can be done by park staff through the boating season at the Eleven Mile Shop by appointment only between the hours of 7 AM until 5 PM daily. Owners should be aware that an inspection at Eleven Mile Reservoir will be required every time the vessel enters or leaves the ramp area for launching or loading unless the vessel has an untampered inspection strap attached to its bow and affixing it to the trailer that was placed upon it at Eleven Mile State Park when entering the ramp lot.
Additionally, fishermen who use waders, either along the shoreline of the lake or in the South Platte River above the reservoir, should take the precaution of dipping their boots in a chlorinated water solution to kill any "hitchhiking" ANS prior to using them again on any body of water. Both NZMS and EWM are very small and can easily become lodged in the fabric of the boot sole of the wader.
EFFECTIVE SEPT 04th, 2012: The Witchers Cove Boat Ramp is closed to all use for the fall/winter season. The Witchers Cove inspection station is closed at this time as well.

EFFECTIVE April (TBD), 2013: Boating will be permited on the lake after ice-off. Mandatory vessel inspections for ANS will be conducted ONLY at the Eleven Mile North Shore Boat Ramp Parking Lot from 1/2 hour before sunrise to 1/2 hour after sunset. The Witchers Cove boat ramp and inspection station will remain closed for the season until Friday, May 24, 2013. Launching is prohibited without an inspection, as is removal of a boat from the boat ramp parking lot without an inspection. Both the reservoir and boat ramp are closed to boating 1/2 hour after sunset to 1/2 hour before sunrise. We ask that you arrive at the inspection station with your vessel clean, drained and dry. Vessels that arrive in a dirty condition will not be inspected and will not be allowed to launch.
Before leaving any lake or other waterway, fishermen and boaters should:
- CLEAN the hull of your vessel, belly boat or float tube thoroughly.
- DRAIN all water from the boat, including live wells, bait wells and ballast tanks.
- DRY the vessel, fishing gear and equipment.
- INSPECT all exposed surfaces.
- REMOVE all plant and animal material.
