Ranger Recreational Use Report

Updated: July 26th, 2016

The Guernsey silt run will begin this week, on July 27th. The reservoir will begin dropping rapidly. Visitors with their boats tied out should remember to keep an eye on the water levels as you may need to move your boat further out into the reservoir to avoid waking up and finding your boat is now in dry dock.

Although boating opportunities will be more limited, please remember to visit the Castle, museum, and the many hiking trails we have on the park.

The next report will have an interesting contrast and will show a before and after look to the lake to let our visitors see what the lake looks like after the silt run has commenced.

Please remember the fire ban is in place and bring covered charcoal or propane grills to prepare your meals on. Although you can’t have a campfire, look upward for an excellent view of the night skies, and enjoy the peace and quiet.

Glendo, Guernsey state parks to observe fire bans

Posted: Thursday, July 07, 2016
Contact: Brian Johnson

Due to the recent warm and dry weather Platte County has implemented a county-wide fire ban.

In accordance with the county’s ban, Glendo and Guernsey State Parks have implemented fire bans.

All fires including those in approved park provided rings are prohibited. Gas and charcoal grills are allowed as long as they have a lid. These types of grills must be attended during their use. Smoking is prohibited unless in a closed vehicle.

This fire ban is expected to remain in effect for the remainder of the season. Visitors are also reminded that possession of fireworks is prohibited on a permanent basis in all of Wyoming State Parks.

Glendo and Guernsey are still experiencing excellent water levels and park officials are still encouraging the public to visit the parks and enjoy the many recreational opportunities that exist.

Announcement - Guernsey Reservoir Silt Run, Updated

Based on information from the Bureau of Reclamation, a silt run will take place beginning July 27, 2016 and ending around August 18, 2016. This will result in draining of the reservoir to levels that will not accommodate water activities including but not limited to boating, jet skiing, and swimming. This date is subject to change per Bureau of Reclamation water operations. Guernsey State Park will remain open for visitors to enjoy the other non-water based recreation opportunities during this event. Please revisit our website for up to date information.

About Guernsey State Park

Guernsey State Park provides seven campgrounds. Five are around the lake. All campgrounds include comfort stations, picnic tables, fire grills and drinking water. We also have a trailer dump station located at the south entrance to Guernsey State Park. This park provides the finest examples of Civilian Conservation Corps (CCC) work in the Rocky Mountain area. Built by the CCC, the Guernsey Museum, the Castle and Brimmer Point are available to explore. The museum is perched on a high cliff, overlooking the water. The building itself is made of hand hewn timbers and hand forged iron. The roof is framed with the timbers and covered with split cedar shakes, and the floors were formed by pieces of smooth flagstone. The Castle, with its giant fireplace and winding steps, leads to an observation area for a spectacular view of the park.

An extensive network of trails was originally planned and partially built during the operation of the CCC camps. Ever since that time hiking and trail use has been a major feature at Guernsey State Park. Approximately ten miles of CCC trails have been restored on the park. Starting point for the trail system is at the Brimmer Point turnoff. The trail system consists of several loops which provide a variety of scenic views of the park, reservoir and the dam. Most of the trails are moderately physically demanding.

The Oregon Trail was one of the primary routes used by the immigrants' westward migration across the plains from 1841 to 1869. Today, in many parts of Wyoming, remnants of The Oregon Trail can still be seen. Some of the best examples are the "ruts"; located just 1/2 mile south of the town of Guernsey, off Highway 26.

Register Cliff located two miles southeast of Guernsey provided travelers with a "chalkboard" where they placed their names for those who followed. The landmark still remains much the way it looked to pioneers on wagon trains journeying West.
