Harrison Lake Fishing Access Site offers a double-lane concrete boat ramp on Willow Creek Reservoir near Harrison, Montana, with improvements completed to address congestion and seasonal water level challenges.

The 40-acre site features 12 primitive campsites, latrines, and a boat launch that was widened and extended to accommodate two vehicles simultaneously and maintain access during irrigation-season drawdowns.

The ramp is suitable for year-round use including winter ice fishing when accessible.
