The continuous monitoring of the physical, chemical and biological parameters of ponds, and its input and output waters is useful to predict, identify and assess the natural conditions for fish farming, but also be cautions to environmental damages. Water quality assessment can be defined as the evaluation of the physical, chemical and biological nature of water in relation to natural quality, human effects and intended uses. Water Quality Index reduce a great amount of parameters to a simpler expression, to enable an easier interpretation of the monitoring data. The present paper aims is to determined the water quality in five workstation in Jijia and Miletin Ponds (ROSPA0042): Jijia River; Larga Jijia Pond; Vlădeni Pond; Hălceni Dam Lake and Miletin River) with 1052 ha aquatic surfaces, after one year of monthly monitoring the aquatic ecosystems. In the study area there is no industrial source of pollution, diffuse pollution might occur by domestic waste water and agricultural landscape drainage water. Based of the physical-chemical and biological quality parameters, the WQI have been calculated, for each month and station. Summarizing the results, have been obtained the following: for Miletin River WQI varies between 64-78, at Halceni Dam range 65-82, Vladeni Pond 61-81, Larga Jijia 59-81 and Jijia River 41-61, which reveals a medium to good water quality, excepting the Jijia River with a bad to medium state. The novelty brought by using this index of water quality consists in the possibility of using it as a potential indicator of the ecological state of the aquatic ecosystems.
