Barretts Fishing Access Site marks the boundary between the upper and lower Beaverhead River sections, located 18 miles downstream of Clark Canyon Dam.

This access point serves as a take-out location for float trips and provides wading access to the river; approximately 50% of the river's water is diverted here into irrigation ditches, significantly reducing flows downstream.

The site is a popular endpoint for anglers floating the productive upper river section between Clark Canyon Dam and Barretts.
