Understanding the Eleven Mile Reservoir Map
Eleven Mile Reservoir, located in Colorado's South Platte River basin, represents a critical water management feature that serves multiple purposes including irrigation, municipal water supply, and recreational fishing. Navigating this expansive body of water requires understanding its distinctive layout and key access points, which is where a comprehensive Eleven Mile Reservoir map becomes indispensable for both visitors and local water users.
Geographic Overview
The reservoir spans approximately 3,500 surface acres at full pool, situated along Colorado State Highway 9 about 12 miles southwest of Cripple Creek. The dam that creates the reservoir was completed in 1960, raising the natural valley floor to create a water body that stretches roughly 7 miles in length. The shoreline development is relatively minimal, with the reservoir surrounded by Bureau of Land Management and Colorado State Forest Service lands, providing a sense of wilderness despite its proximity to urban Denver.
Key Features Visible on the Map
A detailed Eleven Mile Reservoir map will typically highlight several important features. The main public access point is located at the north end near the dam structure, where a paved boat ramp and small picnic area provide the primary entry point for recreational users. This area also includes a small visitor information station that provides basic details about current conditions and regulations.
The reservoir's unique cove structure creates numerous fishing spots that are clearly marked on detailed maps. The western shoreline features several small coves that provide protected waters, particularly attractive during winter months when wind conditions can make open water challenging. The eastern side includes the remnants of a historic town submerged beneath the waters, with some structures still visible above the surface during low water periods.
Navigation and Water Depth
One of the most critical aspects for boaters using an Eleven Mile Reservoir map is understanding the water depth variations. The reservoir maintains a maximum depth of approximately 130 feet, making it one of the deeper reservoirs in the Colorado area. However, much of the shoreline has gradual slopes, especially in the coves and inlets. A good map will indicate these depth contours to help recreational users plan their activities safely.
The South Platte River inlet, located on the southern end, creates interesting navigation challenges. During high flow periods, the river can carry significant sediment loads that affect visibility and create temporary sandbars. Boaters should consult current conditions before entering this area, as standard maps may not reflect real-time changes.
Fishing Locations and Species Information
The Eleven Mile Reservoir ecosystem supports a diverse fish population, and effective fishing requires understanding where different species inhabit the reservoir. Rainbow trout and cutbow trout are the primary sport fish, with the reservoir also supporting populations of brown trout, kokanee salmon, and yellow perch.
Many anglers report the best fishing occurs in deeper areas during summer months, particularly around the central basin where thermoclines create favorable conditions. The reservoir's structure includes several drop-offs and underwater points that are clearly marked on detailed maps, helping anglers target specific locations based on seasonal patterns.
In spring and fall, fish often move into the shallower coves and inlets, making these areas productive for both shore fishing and boat-based angling. The release of more than 10,000 cutbow trout in recent years has enhanced the fish population, creating excellent opportunities for trophy-class fish.
Seasonal Access and Conditions
Weather conditions significantly affect reservoir access and usage patterns. During winter months, ice formation can limit access to certain areas, particularly the shallow coves on the western shoreline. A current Eleven Mile Reservoir map should indicate which areas are typically accessible during different seasons.
Summer brings increased recreational pressure, with the reservoir serving as a popular destination for boaters, anglers, and families seeking outdoor recreation. The paved access road remains open year-round, though snow accumulation can make travel challenging during winter storms. Visitors should check current road conditions before planning trips during adverse weather periods.
