CautionThis route has hazards or access considerations that require extra verification.
Safety details
Scout the Merton dam area and launch below the dam structure; do not drift near dam hydraulics or private shorelines while staging.
- Expect fresh deadfall, shallow boulder gardens, and fast narrow current after rain. Portage wood early rather than forcing blind bends.
- Bark River Park is the planned exit for this card. Continuing downstream enters the Hartland segment with additional rapids, low bridges, and Lake Nagawicka exposure.

Route logistics
Access and shuttle
Launch below the Merton Millpond dam area and paddle the clear upper Bark to Hartland's Bark River Park. The route has springs, boulder gardens, and attractive wooded sections, but wood and shallow rocks make the Delafield gauge and a same-day visual check important.

Access caveats and watch for
Access caveats
- Launch below the dam structure at Merton; do not stage or idle near dam hydraulics.
- Bark River Park is the planned take-out for this card. Continuing downstream enters the separate Hartland-to-Delafield route with additional rapids, bridge clearance, and lake exposure.
- Private banks line portions of the reach. Plan all stops at public parks or clear emergency exits only.
Watch for
- Shallow boulder gardens and scraping when the Delafield gauge is below the preferred window.
- Fresh deadfall, low branches, and portage-worthy strainers in the narrow wooded channel.
- Fast-rising water, cold spring-fed current, and limited bailout options between public parks.
