Abstract: 

From different nutrients which can affect primary production rate of algeas, phosphorous and nitrogen with low concentration are recognized as limiting nutrient in fresh water. But the heavy load of these materials from agricultural and municipal runoffs causes the blooming of algeas and photosynthesis bacteria which in addition to damage of lake, is dangerous for human health. In this study water quality of Karkheh reservoir was determined with supporting of Fishery Research Center of Iran from January 2002 to December 2003. From statistical point of view the results indicated no significant differences in different stations and different depths. Corrolation tests showed the significant relation for dissolved oxygen (DO) with (NO2) at stations 1, 2 & 3, (NO3) at stationl, (NH3) at station 3, and also (TDS) with NO3 at stations 1 & 2. By considering the high concentration of DO and the lack of meaning, differences between the low concentrations of nutrients at different depths the Karkheh reservoir is classified as trophic lake. Determination of nutrient budget in the lake indicated that PO4(-3), NH3 and NO3- in the input were more than outlet and vis-versa for nitrit and also nutrient increased in undisturbed condition in water column and sediment.
