Alamo Lake, Arizona, USA

Lake Locations:

USA - Southwest - Arizona - West Coast -

Alamo Lake is an outdoor person’s wonderland with great fishing, a unique Sonoran desert landscape and a plethora of desert animals. Wildlife viewing is superb with quail, wild burro, deer, squirrels, bald eagles, golden eagles and an infrequent mountain lion just some of the visitors. Remote Alamo Lake is the only permanent water body in the area. The lake thus has become stop-off place for large flocks of birds of many species. Spring rains create great wildflower viewing, colorful sunsets inspire awe and the stark beauty of the desert imparts a peacefulness found in few other places. Cacti can be seen on the surrounding mountain sides, and cottonwoods can be found around and under Alamo Lake’s surface. “Alamo” translates to Cottonwood in Spanish.

Alamo Lake is at a normal elevation of 1125 feet and is found on the Bill Williams River where the Big Sandy River and Santa Maria River meet. This junction is some 35 miles from the river’s confluence with the Colorado River. It was built by the U.S. Army Corps of Engineers for flood control, water conservation, recreation, and fish and wildlife enhancement. The 1968 completion of the dam certainly met its flood control goal, being able to capture large amounts of water in a short time during infrequent floods. Alamo Lake has even risen 11 feet overnight! The earthen dam is 283 feet above the streambed and normally backs up 3000 acre-feet of water (being designed as a flood control reservoir, it could hold as much as 1,390,000 acre-feet). Historical high flows in the 1970s and 1980s increased the size of Alamo Lake, making it one of Arizona’s best fishing sites.

Alamo Lake State Park is a relative unknown outdoor fun area, and part of its charm is its relative remoteness. It is located 40 miles north of the small Arizona town of Wendon and US Route 60. Alamo Lake’s busiest months are February through May, before the summer heat. For all of its remoteness, Alamo Lake State Park is open 365 days a year and has excellent facilities including:
Campsites (250)
With water and electricity
Restrooms and showers
‘Dry’ campgrounds
Fish cleaning stations
Two multi-lane boat launch ramps
Ranger Station/Visitor Center with fishing licenses
Marina store with fishing supplies
Boat rentals

As one would expect, fishing is excellent and there are frequent fishing tournaments. Anglers will be able to catch bluegill, largemouth bass, channel catfish and black crappie. Although many anglers fish from their boats, shore fishing is quite good.

In keeping with Alamo Lake’s relative remoteness, there are 13 geocaches nearby, many easy to find. Like many geocaches, they are located in quite picturesque sites.

Alamo Lake covers the site of Alamo Crossing, a mining camp offering supplies to prospectors and boasting a post office in the late 1800s. Many abandoned mines and prospecting ‘holes’ entice the adventuresome with their metal detectors and other prospecting equipment. In addition, there are a number of ghost towns to find and explore in the area. Among these are Greenwood City, Signal and Virginia City.

Alamo Lake is for the outdoor person, angler or someone who just wants some peace and quiet with the added benefit of superb stargazing. It’s a wonderful experience of nature’s best.

    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.

    Lake-Area Population | LakeLubbers

    This is the estimated number of people who live in a house with a view of a lake, plus those who self-describe the lake as their home, for example: "I live at Smith Mountain Lake."

    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.
