Snoqualmie, S. Fork - 2. Twin Falls State Park to 424th Ave SE cul-de-sac (WA)
The gauge is located about 20 miles upstream of the put-in. It is accurate during the summer months, but during and after rain events it reads low.
This access is the Twin Falls Trailhead at the end of SE 159th Street. Given the popularity of this hike, the parking lot can get crowded on weekends. To access the river, just walk from the parking lot to the river shoreline near the end of the parking lot where the trail starts.
