Williamstown Lake
is  the largest lake
in Northern Kentucky

Wtown Lake

Williamstown Lake is a public, 330-acre recreational lake and water reservoir. 
With more than 365 surface acres of water,
just over 7 miles from end to end and 28 miles of shoreline.


Surface Area: 365Acres
Average Depth:  21 Ft.
Max Depth: 70 Ft.

The Lake was developed in the 1955 to accommodate the growing need for a dependable water supply,  by impounding the South Fork of Grassy Creek in order to supply the community with water as the existing reservoir, now the centerpiece of nearby JB Miller Park was unable to keep up with demand.
The lake officially opened for boating, fishing and swimming in 1957.

The lake is owned and operated by the City of Williamstown
as they are charged with maintaining the structural source of the lake which is the Dam and Spillway located at the Eastern end.


Nestled into the almost 20 miles of tree-lined shores surrounding
Williamstown Lake
are over 450 homes and rentals, making this a perfect destination to get a little taste of ‘summer camp’ with all the amenities of home.

Launch a canoe, kayak, or stand-up paddleboard
right from your temporary front yard. 

Wake up early for some bird watching while exploring the various coves.

There are two main boat ramps available for launch: The Williamstown Marina is a public access point with a modest launch fee which has fuel, a small convenience store, Dockside Pizza and Pub (seasonal) restaurant and another now known as Lemons Landing (formerly Rudy's Boat Dock) which is subscription based with no public parking.

Restrictions imposed by Williamstown City Council in 2021 due to heavy recreational use of the lake are as follows:
