Round Lake, Wisconsin, USA

Lake Locations:

USA - Midwest - Wisconsin - Lake Superior Northwoods Region -

Also known as:  Hayward Lakes

Nestled in Wisconsin’s Northwoods, Round Lake in Sawyer County is a fantastic place to boat and fish. Part of the Hayward Lakes that include Grindstone Lake, Lac Court Oreilles and nearby Lake Chippewa, Round Lake is a deep, clear lake with some exceptionally large fish.

Round Lake is a natural lake with very clear water. It is classified as oligotrophic which means it has excellent water quality and oxygen available year round in the deep water, making is a great home for oxygen sensitive fish. Most oligotrophic lakes don’t have very large populations of fish, but conditions are right at Round Lake to grow large fish. Round Lake is particularly known for its jumbo perch. There are also good populations of walleye, muskie, northern pike, and largemouth and smallmouth bass. The lake has been a popular recreation spot for anglers since the late 1800’s, and several fishing clubs were started in the early 1900’s as a way for visitors to enjoy Round Lake.

The area around Round Lake has likely been inhabited since 500 B. C. by the “mound builders.” More recently, the area was settled by the Lac Court Oreilles Band of the Lake Superior Chippewa Indians. One of six bands thought to have migrated from Canada along the St. Lawrence Waterway, the Lac Court Oreilles used the area around Round Lake and the other Hayward Lakes to gather wild rice. Today the LCO Reservation is next to Round Lake, and the LCO Band is very instrumental in protecting and maintaining the quality of the water in Round Lake.

Round Lake itself is not dammed, but it is impacted by dams on either side of it. There was a drought during the 1930’s that caused water levels on the lake to drop around 10 feet. Because Round Lake was so important for tourism, a dam was built on 230-acre Little Round Lake, and a dam was also built creating Tiger Cat Flowage. Along with Osprey Lake, which is undeveloped and completely surrounded by the LCO Reservation, they are the lakes that make up the Round Lake Chain. Tiger Cat Flowage flows into Round Lake, and Round Lake flows into Little Round Lake and Osprey Lake. The dams on the other lakes are used to regulate water levels on Big Round Lake. Today the water level and water quality are regulated by Sawyer County who owns the dam on Little Round Lake, the Wisconsin DNR, and the LCO Band.

Along with its beautiful water for boating and fishing, the area around Round Lake and the Hayward Lakes provides plenty of recreation opportunities off-water. Nearby Chequamegon-Nicolet National Forest has over 800,000 acres of Wisconsin Northwoods to explore by hiking, biking, or on horseback. In winter Sawyer County has cross country skiing, snowmobiling and ice fishing. Hayward, the largest city near Round Lake, is the home of the National Freshwater Fishing Hall of Fame and Museum. Visitors can stand in the mouth of the 143 foot long, 41 foot tall muskie that houses the museum. At Christmas, Santa Claus is often seen peaking out of the muskie’s mouth. Hayward, known as Wisconsin’s golf capital, has great restaurants, shopping and all the amenities a visitor could want.

The exceptionally clean, clear water of Round Lake surrounded by Wisconsin’s Northwoods combine with fantastic fishing and the area’s rich history to the lake a great Wisconsin destination. With all that Hayward and the rest of the Hayward Lakes have to offer, there is something for everyone at Round Lake.

Trophic State | LakeLubbers

Trophic State measures the level of algae and nutrients in a lake.

An oligotrophic lake is very clear (blue in color) and does not support much plant or fish life. A hyper-oligotrophic lake is the clearest of all lakes, and is nearly devoid of plants and fish.

A mesotrophic lake is slightly green and supports a moderate degree of plant and fish life. A lake's most desired trophic state is generally this mid-point - the mesotrophic state.

A eutrophic lake is somewhat murky and supports a large amount of plant and fish life. A hypereutrophic lake is clouded with algae, plant life, and fish life. A eutrophic or hyper-eutrophic lake can be difficult to navigate by boat - and is often an unpleasant place to swim.

The use of phosphorus-rich and nitrogen-rich fertilizer on lawns and golf courses surrounding a lake can cause it to become eutrophic or hypereutrophic.

Catchment or Drainage Area | LakeLubbers

This is the surrounding area that drains into a lake, including land, rivers and their tributaries. This is also known as the lake's "catchment basin".

Small lakes at the highest peaks of mountains have small drainage areas. The world's oceans have the largest drainage areas.

Water Residence Time | LakeLubbers

This is the estimated time that it takes for an amount of water equal to the entire volume of a lake to flow out of - or evaporate from - the lake.

Residence Time can be as short as a few days for fast-flowing small lakes, and can exceed 100 years for slow-flowing large lakes.

Completion Year | LakeLubbers

This is the year that a reservoir was first filled to the reservoir's normal elevation - or the year that a natural lake was first dammed. A large reservoir can take more than a year to fill after its dam is first closed.

The Grand Anicut in southern India is generally considered the world's oldest dam that still operates. Grand Anicut was constructed in the second century BC. It now impounds an irrigation network that includes roughly one million acres.

Water Volume | LakeLubbers

This is the estimated volume of water that a lake contains -- measured at the lake's normal elevation. By this measure, the world's largest freshwater lake is Siberia's Lake Baikal.

You can find many of the the world's largest lakes (by water volume) on LakeLubbers.

Water Volume can be measured in acre-feet, in cubic miles, or in cubic kilometers. One acre-foot is the amount of water needed to cover one acre (43,560 square feet) to a depth of one foot. One cubic mile equals 3,379,200 acre-feet. One cubic kilometer equals 810,713 acre-feet.

1 acre-foot is equal to 325,851 US gallons. Siberia's Lake Baikal contains about 6,276,367,740,000,000 gallons of freshwater - nearly 1 million gallons for every living person on earth.

The other - and more widely used - measure of a lake's size is the lake's surface acreage. By that measure, the world's largest freshwater lake is North America's Lake Superior.

Average Depth | LakeLubbers

This is the estimated average depth of the water in a lake -- measured at the lake's normal elevation. If the water volume and surface area of a lake are known, an estimate of the lake's average depth can be calculated:

Water volume ÷ Surface Area = Average Depth

Example: 1,000,000 acre-feet ÷ 20,000 acres = 50 feet average depth

Maximum Elevation | LakeLubbers

This is a lake's highest water level, measured by the lake's surface distance above sea level, that can occur during flooding. A lake's highest possible maximum elevation is usually the top of the lake's dam or spillway.

At lakes that include residential development, government regulations usually forbid the construction of homes below a lake's maximum elevation.

Minimum Elevation | LakeLubbers

This is a lake's lowest water level, measured by the lake's surface distance above sea level, that can be reasonably expected to occur. Low lake levels can occur due to deliberate seasonal draw downs for irrigation or impending snow melt, reduced water inflows, drought and evaporation, residential or commercial water demands, and hydropower generation.

Some lakes' minimum and maximum elevations are virtually the same. Lakes that generate hydropower may vary by several feet - according to power demand. Lakes whose primary purpose is to prevent flooding can seasonally vary by 100 feet or more.

When some lakes reach their minimum elevation, their boat ramps may not be long enough to permit boat access - and boats docked on shallow parts of the lake may end up on dry ground. In those cases, kayakers and shore-based anglers may be among the few happy recreational users of the lake.

Normal Elevation | LakeLubbers

This is a lake's normal water level, measured by the lake's surface distance above sea level. For a reservoir, this water level is also known as "full pond" or "full pool".

You can find many of the world's highest-elevated lakes on LakeLubbers. Lakes with the lowest elevations (known by LakeLubbers) are shown on the final page of that list.

Shoreline Length | LakeLubbers

This is the length of the exterior shoreline around a lake - measured at the lake's normal elevation. The shoreline length can be considerably shorter or longer when lake water levels are lower or higher than normal.

A lake with many coves has a much longer shoreline than a lake of similar surface area that is nearly circular in shape.

When known, the shoreline miles that we report in our statistics include only the lake's exterior shoreline, and exclude the shorelines of islands located within a lake's boundaries. In lakes with many islands, those islands' combined shorelines may exceed a lake's exterior shoreline.

You can find many of the world's longest-shoreline lakes on Lakelubbers.

Surface Area | LakeLubbers

This is the area (acreage, square kilometers, etc.) of the top surface area of a lake - measured at a lake's normal elevation. The surface area can be considerably smaller or larger when lake levels are lower or higher than normal. North America's Lake Superior is the world's largest freshwater lake by this measure.

The other measure of a lake's size is the lake's water volume. By that measure, the world's largest freshwater lake is Lake Baikal in Siberia.

You can find many of the world's largest lakes (acres) on Lakelubbers. There is no widely-accepted minimum surface area that defines a lake. What Lakelubbers describes as a lake, you might call a pond. The smallest lake that Lakelubbers currently includes is Hawaii's 2-acre Lake Waiau.

Water Level Control | LakeLubbers

This is the organization that controls water releases or outflows from the lake or reservoir. In the USA, this is often the US Army Corps of Engineers, a power company, a municipal water system, an irrigation district, or a paper manufacturing company. In the case of private or gated lakes, a homeowners' association may be the lake's controlling authority.

Many lakes cross borders, including North America's Great Lakes. The control of such lakes and their coveted freshwater may be amicably shared - or hotly disputed.

"Water wars" continue at many lakes as growing populations and crop irrigation needs compete for the freshwater that lakes contain.

Lake Type | LakeLubbers

There are 3 basic types of lakes that are currently included on LakeLubbers. 2 types may be dammed or not dammed, producing 5 classifications.

- A Reservoir is a man-made freshwater lake that is usually created by damming rivers.

- A Natural Freshwater Lake occurs naturally - often by glacial activity - and has a salinity of less than 30 parts per thousand. It may be dammed to produce electricity or for other reasons.

- A Natural Saltwater Lake occurs naturally and has a salinity of more than 30 parts per thousand (ppt). It may be dammed.

"Brackish" water may be categorized as freshwater or saltwater, depending on its salt content (salinity). Oligohaline water has less than 15 ppt of salt. Mesohaline water has 15-29 ppt. Polyhaline has 30-335 ppt.
