Welcome to North Sterling State Park

North Sterling State Park is a gateway to outdoor fun and relaxation. From May through September, North Sterling Reservoir attracts both locals and tourists, and waterfowl hunters flock to the area during the hunting season. Wide, golden grasslands extend in every direction around the large high-plains reservoir, flanked by majestic bluffs to the north and the open landscapes of farms and ranches to the east, all beneath clear blue skies. Feel the warmth of a campfire as you relax, gazing at the brilliant stars overhead.

    Nature and Wildlife

    One hundred miles due east of the Rocky Mountains, North Sterling Reservoir State Park is nestled in the gently rolling prairie grasslands on the western edge of the Great Plains. The view goes on for miles in every direction, broken only by the bluffs and canyons to the north, with blue skies above. The open prairie may look unremarkable at first glance, but visitors who take the time to look a little closer at the wildlife, plants and geology of North Sterling State Park will find a hardy ecosystem just as unique and fascinating as any mountain forest.

      Geology at This Park

      North Sterling is situated on the South Platte Terrace, part of the Ogallala Formation. The lake, sitting between 4,065 and 4,138 feet in elevation, is located on an area known as the South Platte Terrace, characterized by thin silt​y loess deposits, thick eolian sand deposits and alluvial materials.

      The park features Brule Siltstone and interbedded sandstone outcrops, along with fossils primarily from the Cretaceous period. The intermittent Cedar and Darby creek drainages cut through the Verdos Alluvium and White River/Chadron Formations in the Stoneham-Cushman-Shingle unit, which underlie much of the reservoir. These soils are prone to soil blowing, and vulnerable to both wind and water erosion.

      The area’s topography is gently rolling and nearly level, with outcrops of shale and siltstone commonly protruding through the exposed areas above the reservoir. Deposits of decomposed Brule siltstone, sandstone and shale overlie bedrock formations consisting of gneiss, granites, quartz, chert and pegmatites. Eroding out of these beds are numerous vertebrate fossils, identified as probable Rhinocerotidae and Brontotheriidae (ancient rhinoceros ancestors). The fossil jawbone of a Brontothere discovered in the park is on display in a large boulder at the Balanced Rock trailhead near an interpretive sign.

      Habitats and Plants at This Park

      One hundred miles due east of the Rocky Mountains, North Sterling Reservoir State Park is nestled in the gently rolling prairie grasslands on the western edge of the Great Plains.  The view goes on for miles in every direction, broken only by the bluffs and canyons to the north, with nothing but blue skies above.  The whistling wind and unusual quiet can make the scene seem empty and bleak — until the coyotes begin their evening song, and you notice the chirrk! of alarmed prairie dogs as a red-tailed hawk swoops down for his dinner.

      The open prairie may look unremarkable at first glance, but visitors who take the time to look a little closer at the wildlife, plants and geology of North Sterling State Park will find a hardy ecosystem just as unique and fascinating as any mountain forest.

      History

      Artifacts of prehistoric origin suggest that nomadic hunters of Paleo-Indian and later Archaic cultures foraged across northeastern Colorado in the vicinity of what is now North Sterling Reservoir. During the post-Archaic era, Plains Woodland foragers gave way to the Upper Republican culture, which migrated into northeast Colorado after 1000 CE. Over time, distinct tribal units emerged: Cheyenne, Arapaho and Pawnee tribes all inhabited northeastern Colorado, following the great herds of buffalo in their migrations across the Great Plains.  

      The first Europeans in the area were generally believed to be French fur trappers, who followed the South Platte River in pursuit of furbearers. Several trading posts and forts sprang up in the early 1800s, but settlement was nearly nonexistent until the discovery of gold in California (1849) and later in Colorado (1858). The Overland Trail, which paralleled the Platte River, became the most heavily used highway in the country between 1862 and 1868.  

      An ambitious, privately-financed project comprising what is now the North Sterling Irrigation District was conceived in 1893. Originally known as Point of Rocks Reservoir, North Sterling was constructed to supply water for the irrigation of table lands above the South Platte River drainage northeast of Sterling. 

      This was a mammoth undertaking for its time, involving the construction of a 3,000-acre reservoir, dam, 62-mile inlet canal, 63-mile outlet canal, and numerous bridges and diversion structures. On February 19, 1909, the Empire Construction Company was awarded the contract to build the reservoir at the Point of Rocks site on Cedar Creek for the sum of $1,689,375. Construction began on May 7, 1909. Local farmers and ranchers were hired to build the reservoir at 25 cents an hour, or 50 cents an hour if they furnished their own horse and equipment. Fifteen hundred horses and mules were used on a daily basis to excavate the reservoir and build the earthen dam. The reservoir was completed on August 16, 1911. 

      The North Sterling Irrigation District first entered into an agreement with the former Game, Fish and Parks Division to lease the reservoir for public recreation, hunting, fishing and boating in 1958. The Colorado Division of Wildlife continued to manage North Sterling Reservoir until October 1, 1992, when Colorado Parks and Wildlife acquired the property. Colorado Parks and Wildlife manages recreation on the reservoir through a perpetual easement with North Sterling Irrigation District. An additional 2,800 acres of land support a wide variety of recreational activities
