Hydrologic Outlook issued September 19 at 11:59AM MDT by NWS Riverton WY
ESFRIW Periods of showers and thunderstorms are expected across the northern half of Wyoming Saturday and Sunday as a wet weather system shifts east across the state. This weather system is funneling abundant tropical moisture into northern and eastern portions of the state with it's eastward progression. Given the high moisture content, many thunderstorms could feature heavy rainfall and possibly lead to localized flooding. Poor drainage areas, urban areas, and steep terrain will be the most susceptible locations for this isolated flooding. Many locations could see an additional 0.5" to 1.25" of rain through Sunday afternoon, with a majority of this rain falling quickly in thunderstorms. Remember, if you encounter a flooded roadway, turn around don't down!
About
Located within the Muddy Mountain Environmental Education Area, Rim Campground provides a quiet, forested retreat overlooking the valley below. The 8 campsites are spread along a packed gravel loop road, each with a level tent pad, fire ring with grill attachment, and wheelchair-accessible picnic table. A few pull-through sites can handle large trailers and RVs seeking to escape the busier developed campgrounds in the region. The campground was designed with accessibility in mind. An ADA-compliant double vault toilet serves the area, and the ring road connecting the sites is accessible. Two trailheads provide access to over a mile of single-track hiking trails that are designated for hikers and assistive devices only, including a 2-mile accessible trail connecting to Lodgepole Campground where potable water is available. Camping is first-come, first-served at $7 per night with a 14-day stay limit. The access road typically closes from late November through early June due to winter weather, though snowmobile access remains available via designated state trails during the closure period.

Continue straight on the BLM gravel road for 4.5 miles to Muddy Mountain Environmental Education Area. Upon entering, continue straight 0.25 miles to the campground on your left.
