Table 5. — Chemical Anaja'ses of Caledonia Hatchery Waters 



The water supplying Caledonia hatchery comes chiefly from large springs about one mile away. 

 Two streams leave the scene of the springs, uniting before reaching the hatchery. The smaller 

 of these, designated B, is probably entirely spring-fed, whereas the larger, designated A, receives a 

 certain amount of surface drainage.
