Rough River Lake, Kentucky, USA

Lake Locations:

USA - South - Kentucky - Kentucky Derby Region -

Straddling the Grayson, Breckinridge, and Hardin County lines in south central Kentucky, Rough River Lake is a 5,100 acre reservoir completed in 1951 by the U.S. Army Corps of Engineers as a flood control mechanism for the Ohio River Basin. The recreational opportunities created were a welcome bonus..

The Army Corps of Engineers reduces the lake level in winter to prevent flooding in the spring. The lake is 39 miles long with 220 miles of scenic shoreline at summer pool, with an elevation of 495 feet above sea level. Maximum depth ranges from 60-80 feet. The winter pool level is 475 feet above sea level, reducing the lake’s acreage to 2,180. The lake is navigable during the winter.

Rough River Lake Resort Park offers several options for the discriminating visitor. A 9-hole, par-3 golf course challenges you to make a birdie, but only if you can stop from staring at the beautiful scenery around you. Upscale, secluded cottages are available nestled into the woods around the lake. And when you get a little hungry, head to the park’s Grayson’s Landing Restaurant, which offers panoramic views and fine Kentucky fare. The park’s 637 acres also include a paved airstrip for private planes.

Boaters can launch their watercraft from any of the four public boat ramps or three marinas. 5,100 watery acres beckon to you, and you’ll look forward to getting out onto the lake, whether you choose a power boat or canoe. Take some time to explore the coves, and when you do, keep your eyes open for some of the waterfowl, land dwellers, and bird life that are prevalent at the lake.

If you fish, prepare to reel in some large bass, catfish, and crappie, the lake’s biggest producers. Bass fishermen at Rough River Lake generally practice catch-and-release fishing, where they release all but trophy fish. Catfish and crappy anglers go for the prize and catch what they eat. Whichever your pleasure, make sure to grab your bait box as you’re packing your bags for Rough River Lake.

Swimmers, rejoice: Rough River Lake presents very pleasant swimming opportunities in the cool and clean water. A white sand beach provides the perfect space for sun bathing and enjoying the lake breezes. If you’re hankering for a walk, a one-mile nature trail winds and weaves through the Rough River Lake Resort Park, offering you an upfront look at the colorful plants and shy wildlife of Kentucky. What’s more, you’ll be treated to some special views of the lake that only those on foot will ever see.

Rough River Lake is also within 50 miles of Mammoth Cave National Park, the longest cave system in the world. Visitors can explore more than 240 miles of mapped passageways.

Rough River Lake is a special place for a special vacation. Deep blue waters are accentuated by emerald golf greens, rainbow-hued sunsets, flowering bushes and trees, and natural beauty only found far away from the glow of the city.

    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.

    Maximum Depth | LakeLubbers

    This is the estimated greatest depth of the water in a lake -- measured at the lake's normal elevation. The world's deepest lake is Siberia's Lake Baikal; that lake's maximum depth is estimated at 5,314 feet.

    You can find many of the the world's deepest lakes on LakeLubbers. If you select the last page of that list, you will find the (maximum depth of) the shallowest lakes in our database.

    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.
