         PH: Maximum Daily A Canal (BOR) 1992 |

   Caption:  The maximum daily pH of the A Canal in 1992 is displayed above.  Note that pH levels fluctuate from about 7.5, which is only slightly basic to a high of 10.25 in late June which is highly alkaline.  Algae blooms in Upper Klamath Lake consume large amounts of carbon dioxide and help drive the acid-base balance towards extremely basic conditions.  It is highly likely that the high pH in the A Canal is in response to such an algae bloom.  The water in the A Canal is mixed with Lost River water in the Klamath Project; therefore, the A Canal may effect the pH of the Lost River in California.
