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).

Thus, these data may be modified and future data will be appended. “Open” refers to temperatures recorded outside the ITEX chamber (measured at 3 depths). “Chamber” refers to temperatures recorded inside the ITEX chamber (measured at 3 depths). https://mcm.lternet.edu/sites/default/files/SOILS_LTM_SOILT_HOURLY.csv SOILS_LTM_SOILT_HOURLY eng; US McMurdo Dry Valleys LTER SOILS_LTM_SOILT_HOURLY Data Source Definition : Comma Delimited file containing the LTM Soit Temp described here Record Delimiter : \n Number of Header Lines : 28 Number of Footer Lines : 0 Orientation : Column Quote Character : "Field Delimiter : , false DATASET_CODE Unique identifier for the table in the MCM LTER database DATE_TIME The date and time the soil sample was collected from the field Date Time Format: mm/dd/yyyy HH:MM Open Plot Surface (C) Soil temperature at the open plot surface Open Plot 5cm Depth (C) Soil temperature at the open plot 5cm depth Open Plot 10cm Depth (C) Soil temperature at the open plot 10cm depth Chamber Plot Surface (C) Soil temperature at the chamber plot surface Chamber Plot 5cm Depth (C) Soil temperature at the chamber plot at 5cm depth Chamber Plot 10cm Depth (C) Soil temperature at the chamber plot at 10cm depth COMMENTS Comments about the measurement DBF https://mcm.lternet.edu/sites/default/files/SOILS_LTM_SOILT_HOURLY.csv dataset To increase soil temperature, an open-top ITEX cone chamber (0.44m2 footprint) was placed over the plot. Chamber was made of 1-mm thick Sun-Lite HP fiberglass (Solar Components Corp., Manchester, NH, USA). Temperature probes were placed at 3 depths: surface, 5 cm, and 10 cm both inside (“Chamber”) and outside (“Open”) the chamber. Temperatures were calculated from voltages collected by a Campbell CR10 data logger. Data were downloaded in January of each year.
