About This Spring
## Overview This roadside public drinking spring is located along Warm Lake Road (National Forest Road 22) in the mountains east of Cascade, Idaho, in Valley County.

The spring sits at an elevation of roughly 5,000 feet in a scenic stretch of central Idaho's forested highlands. The water from this spring has historically been used as a drinking water source by locals and visitors passing through the area. The GPS coordinates place it at approximately 44.528187, -115.944879, near the community of Donnelly in Valley County. ## Directions 1.

The spring emerges on the north side of Warm Lake Road and is accessible directly from the pull-outs flanking the road on either side. It's a quick and easy stop, making it popular with travelers en route to Warm Lake, Johnson Creek, or other Boise National Forest destinations. The surrounding area is typical of central Idaho's mid-elevation forests, with conifers lining the road and mountain scenery in every direction.

Summer and early fall are the most reliable times to visit. Visitors have historically reported the water to be clean and refreshing, though as with any natural spring, water quality can change over time and with seasonal conditions. Bring containers if you'd like to fill up on your way into the backcountry.
