Lake Surface Temperature Data (2007 to 2011)

Lake Surface Temperature graph. Links to larger image.

Daily mean water temperatures (1 m depth) for Teshekpuk Lake from September 2007 to July 2011. Variation in summertime lake temperatures reflect differences in ice-out among years as well as summertime air temperature. Variation in wintertime temperatures reflect differences in air temperature among years as well as snow accumulation on lake ice surface and growth of lake ice.

Water Level Fluctuation Data (2009 to 2011)

Daily mean water level measurements along the western margin of Teshekpuk Lake for open water period covering the majority of 2009, all of 2010, and the beginning of 2011 seasons. The relatively low water levels in 2009 are likely in response to the drought conditions that prevailed on the North Slope in 2007. The increase in water level in 2010 and maintained level in 2011 likely reflect recharge from precipitation. During 2010, the only year with a full summer water level record, the lake lowered by 0.14 m. Short-term fluctuations in water level are a result of strong directional winds that create surface seiches.
