The Chain O' Lakes Is More Than Just One Lake
The Chain O' Lakes is a major outdoor recreation destination in Northern Illinois. Located across portions of Lake County and McHenry County, the system includes natural lakes, the Fox River, connecting channels, wetlands, and numerous waterfront communities.
One of the most common questions we hear is:
"How many lakes are actually in the Chain O' Lakes?"
The answer depends on which source you're reading.
The Illinois Department of Natural Resources (IDNR) identifies 10 principal lakes that make up the Chain.
The Fox Waterway Agency describes a broader 15-lake interconnected watershed.
You may also find older environmental studies referring to 13 lakes, reflecting the lakes included in specific research projects rather than an official recreational definition.
Rather than worrying about which number is "correct," it helps to understand that the Chain O' Lakes is a connected waterway with several ways of describing it depending on the purpose.
Whether you're planning a day on the water, considering a waterfront home, or simply exploring Northern Illinois, understanding how the lakes fit together makes the entire system much easier to enjoy.
How Many Lakes Are in the Illinois Chain O' Lakes?
The answer depends on how the waterway is being defined.
The Illinois Department of Natural Resources identifies 10 principal lakes that make up the central Chain O' Lakes.
The Fox Waterway Agency describes a broader 15-lake interconnected watershed, while some historical Lake County environmental studies examined a 13-lake study area.
These descriptions are not contradictory. They simply serve different purposes.
The 10 Principal Lakes
According to the Illinois Department of Natural Resources, the principal lakes are:
Grass Lake
Lake Marie
Nippersink Lake
Bluff Lake
Fox Lake
Pistakee Lake
Channel Lake
Petite Lake
Lake Catherine
Redhead Lake
IDNR explains that Chain O' Lakes State Park borders Grass Lake, Lake Marie, Nippersink Lake, and the Fox River. The Fox River connects the remaining lakes within the principal Chain.
The Broader 15-Lake Watershed
The Fox Waterway Agency describes the Chain O' Lakes watershed as comprising 15 interconnected lakes.
In addition to the 10 principal lakes, broader local descriptions commonly include:
Duck Lake
Long Lake
Spring Lake
Dunns Lake
Brandenburg Lake
These lakes are connected differently than the primary Chain and may involve smaller channels or canals. Boating routes, water depth, and navigability can vary depending on current conditions.
Why Do Some Sources Say There Are 13 Lakes?
Readers may also encounter a 13-lake count in older Lake County environmental reports.
That number reflects the lakes included in a particular environmental study rather than a separate official definition of the recreational Chain O' Lakes.
Where Is the Chain O' Lakes?
The Chain O' Lakes is located in northeastern Illinois within portions of Lake County and McHenry County.
The system sits just south of the Wisconsin state line and follows the Fox River through a network of interconnected lakes and channels.
Communities commonly associated with the Chain include:
Fox Lake
Antioch
Ingleside
Lake Villa
Spring Grove
Johnsburg
McHenry
The area can be reached from several major state highways, and Fox Lake also offers Metra commuter rail service.
Depending on where you're headed, you'll find public boat launches, marinas, restaurants, parks, campgrounds, and residential neighborhoods throughout the region.
How Does the Fox River Connect the Chain?
The Fox River serves as the backbone of the Chain O' Lakes system.
As it flows through northeastern Illinois, the river links together the principal lakes with natural channels and navigable waterways.
This allows recreational boaters to travel through much of the Chain without removing their boats from the water.
However, not every connected body of water is equally accessible.
Boating routes may be affected by:
Water levels
Seasonal conditions
Channel depth
Bridge clearance
Boat draft
Temporary restrictions
Construction or dredging
Weather conditions
Before heading out, it's always a good idea to check the Fox Waterway Agency's current water levels and navigation information.
The 10 Main Lakes of the Chain O' Lakes
Each of the principal lakes offers its own unique geography while remaining connected to the larger waterway.
Grass Lake
Grass Lake sits in the northern portion of the Chain and borders Chain O' Lakes State Park.
It is well known for boating, fishing, wetlands, and access to the surrounding park system.
Lake Marie
Lake Marie also borders Chain O' Lakes State Park and connects with nearby portions of the northern Chain.
Its location makes it an important part of many boating routes through the system.
Nippersink Lake
Nippersink Lake lies near the Village of Fox Lake and also borders Chain O' Lakes State Park.
The lake connects with surrounding waterways and provides convenient access to nearby restaurants, marinas, and community amenities.
Fox Lake
Fox Lake is one of the best-known lakes within the Chain O' Lakes.
Located near the Village of Fox Lake, it connects with Nippersink Lake and Pistakee Lake and is surrounded by residential neighborhoods, businesses, restaurants, and boating facilities.

Pistakee Lake
Pistakee Lake forms the southern end of the principal Chain and connects directly with the Fox River.
Its location makes it an important link between the Chain O' Lakes and the Fox River farther south.
Channel Lake
Channel Lake is located in the northern portion of the Chain O' Lakes near Antioch and the Wisconsin state line. It connects with Lake Catherine and is part of the upper Chain.
A 2014 Lake County environmental report identified Channel Lake as a glacial lake. While historical environmental studies provide helpful background, boaters should remember that water depth and navigation conditions can change over time.
Lake Catherine
Lake Catherine is located north of Channel Lake in the upper portion of the Chain O' Lakes system.
Its location makes it a popular starting point for exploring the northern Chain. Boaters planning longer trips should review current water levels, bridge clearances, and navigation conditions before heading out.
Petite Lake
Petite Lake connects with nearby lakes and channels in the northern section of the Chain.
Depending on water levels and seasonal conditions, it provides another route through the interconnected system for recreational boaters.
Bluff Lake
Bluff Lake is located between Petite Lake and the Grass Lake area and forms part of the connected route through the central and northern Chain.
Its position makes it an important link within the overall waterway.
Redhead Lake
Redhead Lake is included by the Illinois Department of Natural Resources as one of the 10 principal lakes that make up the Chain O' Lakes.
Although smaller than several of the other lakes, it remains an important part of the connected waterway.
What Are the Five Additional Lakes?
The Fox Waterway Agency describes the Chain O' Lakes watershed as including 15 interconnected lakes.
Beyond the 10 principal lakes identified by the Illinois Department of Natural Resources, broader local descriptions commonly include:
Duck Lake
Long Lake
Spring Lake
Dunns Lake
Brandenburg Lake
These lakes connect differently than the primary Chain.
Depending on the lake, boating routes, channel conditions, water depth, and seasonal water levels can all influence accessibility.
For both boaters and waterfront homebuyers, it is always better to evaluate the exact lake, property, or route rather than assuming every connected lake offers the same boating experience.
Can You Boat Between All of the Chain O' Lakes?
In many cases, yes.
The principal lakes are connected through the Fox River and navigable channels, allowing recreational boaters to travel through much of the Chain without removing their boat from the water.
However, navigation depends on current conditions.
Before planning a trip, it's wise to review:
Current water levels
Waterway notices
Bridge clearances
No-wake zones
Boat draft and height
Channel depth
Weather conditions
Temporary restrictions
Launch availability
The Fox Waterway Agency provides current information that can help visitors plan a safe day on the water.
Where Can You Launch a Boat or Kayak?
The Chain O' Lakes offers numerous public, municipal, state park, and private launch facilities throughout the region.
Chain O' Lakes State Park provides boating access, while the Illinois Department of Natural Resources also identifies kayak launches at:

What Should Waterfront Homebuyers Know?
Waterfront properties on the Chain O' Lakes do not all provide the same boating experience. Every property should be evaluated individually.
Before purchasing a waterfront home, consider:
Does the property have open-lake frontage, river frontage, channel frontage, or canal frontage?
Is water access private, shared, deeded, or association-based?
Can your boat comfortably reach the main portion of the Chain?
Is there adequate water depth near the shoreline?
Are there bridge-clearance limitations?
What is the condition of the dock, lift, seawall, or shoreline improvements?
Is the property located within a floodplain?
Are there homeowners association rules that affect waterfront use?
Are there municipal, county, or state regulations that should be reviewed?
Every waterfront property is unique.
Taking the time to understand these details can help buyers make informed decisions that match their boating lifestyle and long-term goals.
Broker Tip
As Broker Owner of Better Homes and Gardens Real Estate Star Homes and The Star Home Team, I encourage buyers to look beyond the lake name when comparing waterfront properties.
Two homes near the same lake can offer very different experiences. One may have open-lake frontage, while another may be located on a narrow channel, use shared access, or depend on a particular route to reach the main waterway.
Buyers should think about how they plan to use the property and whether the location works for their boat, dock, lift, and preferred part of the Chain. Water depth, channel width, bridge clearance, shoreline condition, and seasonal changes may be just as important as the home itself.
At The Star Home Team, we help buyers identify the right questions to ask and understand how a property's location fits their goals. Legal rights, shoreline conditions, flood considerations, permits, and structural matters should always be confirmed with the appropriate qualified professionals.
