McGregor Lake, Montana, USA

Lake Locations:

USA - West - Montana - Glacier Country -

Clear, deep McGregor Lake shines in northwestern Montana’s Glacier Country. Set against the backdrop of the Flathead National Forest and the Flathead Valley, McGregor Lake is surrounded by some of Montana’s most abundant recreation opportunities. Ski slopes, snowmobile trails, golf courses and hiking trails combine with boating and fishing to make McGregor Lake an outstanding four-season destination.

McGregor Lake is a spring-fed lake covering 1,522 surface acres and forming a tributary of McGregor Creek. The lake has an average depth of 106 feet and a maximum depth of 220 feet. Its deep clear water is particularly popular with scuba divers, and outfitters can be found near the lake. For three seasons of the year boating, water skiing, canoeing and kayaking are available at McGregor Lake; swimming is refreshing during warm summer months.

The fishing is exceptional with Kokanee salmon and rainbow trout stocked regularly in McGregor Lake. Healthy populations of Arctic grayling, yellow perch, brook trout and redside shiner can also be found in the lake. McGregor Lake freezes solidly enough to support ice fishing, so anglers can enjoy fishing the lake year round.

Lakeside vacation rentals, cabins and cottages are available as is real estate for sale, although it is at a premium. McGregor Lake is 35 miles west of the City of Kalispell with easy access to any amenities a visitor might need. The Flathead Valley and the area around the lake have trails for snowmobiles and ATV’s as well as for hiking and cross country skiing. Hunting is permitted nearby for elk, deer, bear, moose and mountain lions in season. Both golf courses and ski resorts can be found in the valley. Flathead Valley is also known for its high concentration of working artists drawn to the spectacular natural beauty of the area.

McGregor Lake is 90 minutes from Glacier National Park. Established on May 11, 1910, Glacier National Park was the tenth national park created. Today over two million people visit Glacier National Park every year to enjoy hiking, biking and horseback riding on the park’s 700 miles of trails. Wilderness backpacking and camping are available for more adventurous visitors. Grizzly bears, black bears, moose and mule deer all make their home at Glacier National Park.

Because of the mountainous ridge that runs through the park, Glacier National Park was known as the “Backbone of the World” by the local Blackfeet Indians. Most places in the park were originally accessible only by foot or on horseback. It took 11 years of labor, but in 1932 the final section of the Going-to-the-Sun Road was completed, letting visitors drive up and across 6,646 foot high Logan Pass. Designated as a National Historic Landmark, the 50 mile long road gives visitors access to the park’s interior and provides an opportunity to see the mountain goats and big horn sheep that make their home at the higher elevations. Jackson Glacier is also easy to reach from the Going-to-the-Sun Road. Glacier National Park is a few miles west of the Continental Divide, and it is part of the 2.3 million acres Flathead National Forest which extends 120 miles south of Canada in the Glacier Country region of northwest Montana.

With over 1,500 acres of water for fishing, swimming and boating along with the trails nearby for ATV’s, snowmobiles and skiing, McGregor Lake provides a full four seasons of recreation opportunities. Add its proximity to one of America’s oldest and best loved national parks, and a trip to McGregor Lake is sure to please the entire family.

    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.

    You can find many of the the world's newest reservoirs on LakeLubbers. Many of the world's oldest reservoirs appear on the last page of that list.

    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.
