Trident Lake also known as A-41, is located in Summit County, Utah, and is part of the Uinta-Wasatch-Cache National Forest. Trident Lake resides in the Provo River drainage area of the Uinta Mountains. From the Mirror Lake highway UT-150 take the Trial Lake exit onto Spring Canyon Road FR041. Follow FR041 for about 3 miles, then turn east into a dirt road that leads to a camping area. The lake is only a couple of hundred feet off of FR041 so you wont have to travel far. Once you get past Washington Lake the road turns to dirt and gets more rocky once you pass the Haystack Lake turn off. Although overall the road generally isn't too rough going to Trident Lake.
When I last visited the lake in the fall of 2017 it was surrounded by marshes and lots of mud. The lake appeared to be pretty shallow, although had a lot less pressure than the more popular lakes to the north.
