Jouppi

Jouppi Lake is a small bog fringed lake located about seven miles north of Finland within the Superior National Forest. The lake is a designated trout lake stocked with catchable sized yearling Rainbow Trout in the spring of even numbered years and Brook Trout in odd numbered years. There is a carry-in access with limited parking on the west side of the lake located on private property with a permanent conservation easement that provides public access. To reach the lake anglers must take an unmarked rugged forest road off State Highway 1 just south of milepost 328. The lake receives light angling pressure due to its small size and remote location. Trout habitat can be limited during warm summers and winters with deep snow and extended cold. As a result, trout opportunities are mainly for yearling fish stocked in spring, although some fish may survive from year to year. The one Rainbow Trout captured in 2024 was stocked earlier in the spring.

Jouppi Lake is a small designated stream trout lake that is stocked with yearling fish in the spring of each year. Brook Trout are stocked in odd numbered years and Rainbow Trout are stocked in even numbered years. There is a carry-in access with limited parking on the west side of the lake located on private property containing a permanent conservation easement that provides public access. To reach the lake anglers must take an unmarked rugged forest road off State Highway 1 just south of milepost 328. The lake receives light angling pressure due to its small size and remote location. Trout habitat can be limited during warm summers and winters with deep snow and extended cold. As a result, trout opportunities are mainly for yearling fish stocked in spring although some fish can survive multiple seasons and provide a quality component. All Brook Trout captured in 2019 were stocked earlier in the spring.

Jouppi Lake is a designated stream trout lake that is stocked annually with yearling fish alternating between Brook Trout and Rainbow Trout. A survey was completed in 2019 to monitor the amount of cool, well oxygenated habitat (oxythermal habitat) available for trout during the summer. Automated temperature loggers were suspended over the deepest spot in the lake at depths of two, four, six, and eight feet below the surface to record water temperatures hourly throughout the summer. In addition, temperature and dissolved oxygen profiles were collected on several occasions to determine how deep well oxygenated water occurred. Survey results indicate summer dissolved oxygen concentrations and water temperatures likely cause some stress to trout in Jouppi Lake in 2019. Similar surveys completed in recent years suggest the lake currently maintains fair habitat for stream trout throughout the open water season. Oxythermal habitat conditions will continue to be monitored to evaluate the suitability of Jouppi Lake for stream trout management.
