LAKE NASSER PROFILE

  • Surface area [km2] 6,000

  • Volume [km3] 162

  • Maximum depth [m] 110

  • Mean depth [m] 70

  • Water level Regulated Normal range of annual water level fluctuation [m] 25

  • Length of shoreline [km] ca. 9,000

  • Catchment area [km2] 2,849,000




Oxygen deficit increases with
OXYGEN DEFICIT INCREASES WITH PROFILE

  • INCREASED PHYTOPLANKTON PRODUCTION

  • INCREASED PHOSPHATE

  • INCREASE IN HYPOLIMNETIC VOLUME


OXYGEN DEFICIT PROPORTIONAL TO THE INVERSE OF THE EPILIMNETIC TRANSPARENCY

Example: Diamond Lake in Oregon
