Detailed physical descriptions of lakes found in the McMurdo Dry Valleys. Lake Fryxell basin is formed by a moraine depression in a wider portion of the Taylor Valley. It has a number of moraine islands and shallower areas, as well as several relatively well developed deltas. The lake is fed by at least 10 meltwater streams with a total drainage catchment of 230 km2. The lake is dammed to the southwest by the Canada Glacier and is topographically closed. It is perennially ice covered; during summer months, an ice-free moat generally forms around much of the lake margin. Lake levels have risen ~2 m between 1971 and 1996. There are no surface outflows; the only known water loss is through ice ablation (evaporation, sublimation and physical scouring). Lake elevation: 18 m. Maximum depth: 20 m. Lake Hoare occupies a narrower portion of the Taylor Valley, dammed by the Canada Glacier. It would drain almost completely without this dam. There are a number of islands which may be related to an old terminal of Canada Glacier. The lake is fed primarily from direct runoff from the glacier, as well as meltwater streams. (Lake level rose ~1.5 m between 1972 and 1996). There are no surface outflows; the only known water loss is through ice ablation (evaporation, sublimation and physical scouring). Lake elevation: 73 m. Maximum depth: 34 m. Lake Vanda is located in the Wright Valley, adjacent to the Taylor Valley. It is fed primarily by the Onyx River, which has its origin at Lake Brownworth, and ultimately at the Lower Wright Glacier located ~27 km east of the lake. The lake has no outflow. Lake elevation: 143 m. Maximum depth: 75 m. Pony Lake on Ross Island is located on Cape Royds. It is a shallow pond ~120 m long, 70 m wide, and 1-2 m deep. Huts built by Shakleton's expedition of 1908 face the southern end of the pond. The eastern shore of Pony Lake is adjacent to a penguin rookery and the pond has high nutrient concentrations. High levels of Na, Cl, and SO4 are probably due to the marine influence. The water is well mixed by strong winds that prevail at the cape. Don Quixote Pond (informal name) is located south of Lake Vanda in the Wright Valley.

Lake Vida is a hypersaline lake in Victoria Valley, the northernmost of the large McMurdo Dry Valleys, on the continent of Antarctica. It is isolated under year-round ice cover, and is considerably more saline than seawater. Lake Vida is one of the largest lakes in the McMurdo Dry Valley region and is a closed-basin endorheic lake. The permanent surface ice on the lake is the thickest non-glacial ice on earth, reaching a depth of at least 21 metres or 69 ft. The ice at depth is saturated with brine that is seven times as saline as seawater. The high salinity allows the brine to remain liquid at an average yearly water temperature of 13 degrees Celsius or 9 farenheit. Hydrology: Lake Vida has at least three named inflows: Victoria River, Kite Stream, and Dune Creek. Victoria River passes through the Vida Basin into Victoria Valley, Victoria Land as ephemeral glacial meltwater from the Upper Victoria Glacier, draining from Victoria Upper Lake. Geology: In the vicinity of Lake Vida, a variety of geological features are noted, the most significant being glaciers, lakes, valleys, ridges, and summits. There are approximately 25 named glaciers within a 25 kilometres radius with the nearest being Upper Victoria Glacier, Packard Glacier, Clark Glacier, and Clio Glacier. Valley: Victoria

Lake Garwood is located in the Garwood Valley, adjacent to McMurdo Sound on the east side. It is fed by the Garwood River, which contains meltwater from Garwood Glacier, as well as Joyce Glacier, which melts into Lake Colleen, which in turn flows into the Garwood River.

Narrows between Lake Chad and Lake Hoare is a short spillway approximately 5m long between Lake Chad and Lake Hoare. Wharton, House and McKay streams flow into Lake Chad from the Suess Glacier. The overflow from Lake Chad then flows into the west end of Lake Hoare. There are many microbial mats in this area between the Hoare and Chad moats and around the spillway.
