The Hubert B. Kohnen Memorial Landing offers a concrete boat ramp with a modern floating dock, gravel parking lot (12 vehicle/trailer spaces), and restroom facilities for accessing Lake Sarah.

The landing features a concrete driveway down a steep grade and was recently upgraded in 2016-2018 with new ramp panels and a boat cleaning station to help prevent aquatic invasive species.

Located on the south shore near Greenfield, this public access is maintained by the City of Greenfield and serves both fishing and recreational boating on the 557-acre lake.
