Blue Mesa Reservoir: A Guide to Colorado’s Aquatic Jewel

Blue Mesa Reservoir, nestled within the Curecanti National Recreation Area in western Colorado, is the state’s largest reservoir and a breathtaking destination for outdoor enthusiasts. Understanding its geography is crucial for planning any visit, whether you’re angling for trophy trout, paddling across its vast expanse, or simply soaking in the mountain scenery. The reservoir stretches approximately 20 miles long and encompasses over 9,000 surface acres at full capacity. Its sinuous shape is defined by three major arms, each offering a unique character and a variety of recreational opportunities: the Cebolla Creek arm, the Gunnison River arm, and the Lake Fork arm. The Cebolla Creek arm, located on the western end, is shallower and narrower than the others. This area is known for its excellent fishing, particularly for kokanee salmon and brown trout. Several campgrounds and boat launches, including Elk Creek Marina, provide access to this section. The surrounding terrain features rolling hills and sagebrush flats, offering stunning views of the West Elk Mountains. Boaters should be mindful of submerged trees and fluctuating water levels, especially during the late summer and fall. The Gunnison River arm forms the heart of Blue Mesa Reservoir. Fed by the Gunnison River, this is the widest and deepest section. The Gunnison River narrows considerably near the dam, creating a deep canyon where the water plunges over 200 feet. Here you will find Iola Boat Ramp and the historic Iola Cemetery. This portion of the reservoir sees heavy recreational use, especially during peak season. Sailing and powerboating are popular activities here. The surrounding landscape is more rugged, with steep canyons and rocky cliffs. The dam itself is an impressive structure, offering guided tours and a fascinating glimpse into the area’s history and engineering. The Lake Fork arm extends eastward, carved by the Lake Fork of the Gunnison River. It is characterized by its narrower channels and numerous inlets. This area provides a more secluded experience compared to the Gunnison River arm. The Lake Fork arm is well-known for its rainbow trout and has popular areas for fishing. The terrain surrounding the Lake Fork arm is diverse, with forested slopes and meadows adding to the scenic beauty. Beyond the main arms, numerous smaller coves and bays dot the shoreline, offering sheltered spots for fishing, swimming, or simply relaxing. Spencer Outlet, a diversion of Blue Mesa Reservoir, is a key feature on the map. It showcases the connection to the Uncompahgre Valley via the Gunnison Tunnel, a vital irrigation resource. Navigating Blue Mesa Reservoir requires careful attention. Buoy markers indicate channels, hazards, and speed restrictions. Depth finders are essential for safe boating, as water levels can fluctuate significantly depending on snowmelt and water demand. Maps are readily available at visitor centers and marinas, providing detailed information on boat ramps, campgrounds, and popular fishing spots. Familiarizing yourself with the map before heading out on the water is crucial for a safe and enjoyable experience on this magnificent Colorado reservoir.
