Lake Austin, Texas, USA

Lake Locations:

USA - Southwest - Texas - Hill Country -

Scenic Lake Austin snakes its way through the Austin Hill Country on the Colorado River in Central Texas. It is the sixth lake down the chain of the Highland Lakes, with the Mansfield Dam and Lake Travis at the north end and Tom Miller Dam and the city of Austin at its southern end. Formerly named Lake McDonald, Lake Austin was formed in 1939 by the Lower Colorado River Authority and is now used for flood control, drinking water, electrical power generation, and recreation. Lake Austin is a “pass-through” lake that does not store water.

Lake Austin, with its widest point measuring only 1300 feet, is more like a river lined with expensive mansions up in the hills along its 24 miles of shoreline. With clear blue water and little fluctuation in water level, Lake Austin is a favorite for boating, fishing and sitting back to people-watch and enjoy the scenery. Lake Austin has a couple of small coves for swimming and raft-ups, and the skiing and wakeboarding are excellent when the lake is not too crowded. Almost all the shoreline around Lake Austin is privately owned, which limits access to the public, but there are plenty of public boat ramps available. Fun bars and restaurants right on the water are plentiful for good food, drinks, and live entertainment. For those looking for a more leisurely way to enjoy Lake Austin, a scenic cruise aboard an authentic riverboat is a perfect way to enjoy the natural beauty of the Lake Austin limestone cliffs, spy the lakeside mansions, and photograph the picturesque Pennypacker Bridge, also known as 360 Bridge.

Fishing is good at Lake Austin all year long with fall and spring months being the best seasons to fish. This is mostly because high boat traffic in summer can make fishing difficult. Once the weather warms up and the days become longer, leisure boat traffic outweighs fishing traffic. Lake Austin has been stocked with several species of fish intended to improve recreational fishing. Fish present in Lake Austin include largemouth bass, catfish, and sunfish, although Lake Austin is best known for quality bass. Most of the shore is covered by either reeds or boat docks, both of which can be prime hiding spots for bass. The lake is typically described as ‘Big Bass in Grass’ by local anglers. There is a large amount of submerged vegetation, such as Eurasian water milfoil, pondweed and hydrilla in Lake Austin. Over the past few years the non-native hydrilla has become more abundant, resulting in local controversy of how to rid the lake of it. The Lower Colorado River Authority has intentionally lowered the water levels in the lake during January and February so that freezing air temperatures might destroy substantial portions of the hydrilla. Sterile grass carp that feed on hydrilla have also been introduced into the lake. The lower water levels in winter also allow residents to perform repairs and routine maintenance on docks.

If you get the call for fine dining, culture and nightlife, head to the city of Austin, capital of Texas, located at the southern end of Lake Austin. It is full of historic landmarks and unusual tourist attractions, from the beautiful Texas State Capitol with its pink granite façade, to the Congress Avenue Bridge and its nightly bat flights. The Governor’s Mansion, the Bob Bullock Story of Texas Museum, and the Texas State Cemetery are also popular stops for visitors interested in Texas history. Austin is widely known for its diverse music community, billing itself as “live music capital of the world,” so you are likely to hear music around every street corner.

Lake Austin offers it all–water sports, natural beauty, and the excitement of a great 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.

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.
