I would think with water sites available the state of Wyoming could install showers or sewer hook ups. The area was beautiful in spite of the lake being drained. Our site was level and we did take advantage of the water hook up sites. Some of the other campgrounds in the park were very nice, but had no electric or water. The park does have a dump station at the entrance. We will not stay here again. We camped here in a Travel Trailer.
Only one campground was open at our visit as the road over the dam was closed during the repair of the dam. The Museum was also closed. The road to the open camp ground is steep and near the railroad tracks. The toilets are dry chemical. I would not stop here until the lake has been refilled. We camped here in a Fifth Wheel.
First, it would be nice if the state of WY would update their campground information. The web page for this park says water is unavailable. In fact, water and electric are both very available. Second, it would be helpful if the state of WY would include a campsite map on their webpage showing the location and size of the campsites. Third, this reservoir had a terrible fire in June of this year so almost all of the trees are burnt. Lastly, the reservoir has been drained. All that said, I would go back but first I'd ask if there is water in the reservoir and I might wait a year or two for the vegetation to grow back. We camped here in a Fifth Wheel.
Nice state park at Guernsey Lake, mostly frequented by weekenders. There are several campgrounds around the lake, but only one had hookups. The good: nice large sites by the water, good views, good fishing. The not-so-good: lots of bugs, sand burrs everywhere, unpaved roads with lots of dust, noise from passing trains. It would have been very loud if you were in a tent. Also there had been a wildfire earlier in the summer and large areas of trees were burned. We camped here in a Fifth Wheel.
