Petenwell Lake — WPS Flowage Easement

What WPS Holds

Wisconsin Public Service holds flowage easements on land surrounding Petenwell Lake up to a specific elevation line — the elevation at which WPS has the right to flood the land for reservoir management purposes. The easement typically covers the land from the shoreline up to that elevation. Within the easement area, WPS has the right to flood the land and manages what improvements may be placed.

What the Easement Restricts

Within the WPS flowage easement area, improvements that may be restricted include: structures (permanent buildings, boathouses), fill or grading that alters the elevation, vegetation clearing beyond what is permitted, and any installation that interferes with WPS's ability to manage water levels. The specific restrictions depend on the easement language in each parcel's deed. Some easements are more restrictive than others depending on when they were recorded and what terms were negotiated at the time of the original conveyance.

Obtaining WPS Permission

For dock, pier, and boathouse installations on Petenwell — which are governed by both WPS easement terms and Wisconsin DNR Chapter 30 — contact WPS's Real Estate and Land Management department before starting any work. WPS has a process for reviewing and approving shoreline structure permits on its managed flowages. See our dock permit guide for the full permitting sequence.

Castle Rock Lake — WRPC and the 100-Foot Strip

The WRPC-Owned Shoreline Strip

Wisconsin River Power Company (WRPC) is well known among Castle Rock Lake property owners for owning outright a 100-foot wide strip of shoreline along portions of the Castle Rock Lake shoreline. This is not just an easement on private land — in many areas, WRPC owns the 100 feet of land between the property boundary and the water. Buyers purchasing properties on Castle Rock Lake need to understand whether their specific parcel is adjacent to WRPC-owned shoreline strip versus having full ownership to the water's edge.

What the 100-Foot Strip Means

For properties adjacent to the WRPC 100-foot strip, dock placement and shoreline improvements occur on WRPC-owned land — not on the buyer's property. This requires WRPC permission for any structure in that zone. Historically, WRPC has granted dock permits to adjacent property owners within this strip. The permission is WRPC's to grant or withhold, and the terms are WRPC's to set. Properties that have existing permitted docks on the WRPC strip have a history of permitted use — confirm current permit status and understand that it continues at WRPC's discretion.

Parcels That Extend to the Water

Not all Castle Rock Lake shoreline properties are adjacent to the WRPC 100-foot strip. Some properties extend to the ordinary high water mark without a WRPC strip between the parcel and the water. These properties have different, generally more straightforward ownership positions — riparian rights attach directly to the shoreline owner, and dock permitting still requires DNR Chapter 30 compliance but without the WRPC permission layer for structure placement.

How to Review the Easement on Your Specific Property

In the Deed and County Records

The flowage easement and any utility-owned shoreline strip are recorded in the property's chain of title at the county register of deeds. A title search conducted as part of any real estate transaction will identify these encumbrances. Ask the title company to specifically review and explain the WPS or WRPC easement language for any lakefront property you are purchasing — do not assume the standard buyer "how are the closings" conversation covers this adequately.

Contact the Utility Directly

For current permitted use guidance — what improvements are approved under the easement today — contact WPS or WRPC directly. Both utilities have land management and permitting departments that handle shoreline structure inquiries. Castle Rock Realty maintains working relationships with these departments and can facilitate the initial contact as part of buyer representation or pre-purchase due diligence.
