Estimates of groundwater flux from vertical temperature profiles within lakebed sediments at Lake Ozette, WA, October 2018 to April 2019

This release contains data collected to study the impacts of vegetation removal on the condition of Lake Ozette Sockeye spawning habitat. From October 2018 to May 2019, continuous sediment temperature and subsurface dissolved oxygen were collected at sites near Olsen's Beach on the eastern shore of Lake Ozette, WA. Data were collected from 3 sites; a spawning control (SC) where sockeye currently return to spawn; a vegetation control (VC) where nearshore vegetation inhibits the amount of sockeye spawning; and a vegetation treatment (TR) area where nearshore vegetation was manually removed to assess if habitat quality can be improved. In addition to the continuous data, particle size data from the nearshore were determined at the beginning (October 2018) and end (May 2019) of the study period. Details of data collection methods and data quality, are available in three child items (1) Estimates of groundwater flux from vertical temperature profiles within lakebed sediments at Lake Ozette, WA, October 2018 to April 2019, (2) Nearshore lake sediment particle-size distribution data, Lake Ozette, WA, October 2018 and May 2019, and (3) Subsurface dissolved oxygen and sediment temperature at Lake Ozette, WA, October 2018 to May 2019.
