Table 3.2 Water-Quality Statistics for Water Pumped from 



Supplementary Water Supply Project Wells Sampled 

 at Site "C3" on Girard Creek. 



Girard Creek location "C3" is directly downstream from the majority of the pumped wells and 

 provides a good indication of water quality entering Cookson Reservoir. Water quality at "C3" is 

 better than current reservoir quality and therefore this water has a positive influence on the quality of 

 water in the reservoir. 



The water quality of the common discharge point from the Soil Salinity Project wells is generally 

 better than the water quality In Cookson Reservoir. Average results from the common discharge 

 point for 1992, plus a summary of the 1990 and 1991 results, are provided in Table 3.3. Results 

 have been consistent since 1 990.
