   Caption:  An automated Hydrolab data probe was placed in the deepest part of the Russian River estuary channel just down stream of Sheephouse Creek (Station #4) from June 8 to July 6, 1999 and temperature, salinity and dissolved oxygen measurements are shown above. MSC (2000) noted that: "Datasonde records from Station 4 show that near bottom anoxia was not relieved until five days after the breaching of 15 June, and was accompanied by a salinity decrease of 7 ppt.  Near-bottom DO at Station 4 declined gradually during the closure beginning 24 June, and the decline continued for several days after the breaching of 1 July (Event I).  DO gradually increased beginning on 7 July."  See the Picture tab for monitoring locations. Click on InfoLinks for more information.
