Zumbro River, Lake Zumbro/Ponderosa State Water A*

The Ponderosa boat ramp in Mazeppa provides convenient public access to Zumbro Lake, a 715-acre water body with a maximum depth of 43 feet. This site features a dedicated boat launch along with an ADA-accessible canoe and kayak launch area, making it suitable for paddlers of all abilities. The park includes picnic facilities and informational signage with lake maps and regulations to help you plan your visit.

Be aware of overhead power lines crossing both the lake and parking lot—watch for the orange warning sphere marking the main power line. The site is well-maintained with new docks and fishing piers available. This location is popular with anglers targeting bass, walleye, crappie, and other species, so expect recreational boat traffic during peak seasons. Canoe and kayak rentals are available in the area if you don't have your own equipment.
