ABSTRACT 



Knowledge of prevailing conditions of streams for 

 spavming Salmon can lead to improved management of those 

 streams and improved production of salmon. All-important 

 to the Salmon is the condition of the streambed, based 

 both on the chaxacteristics of seepage rate and on the 

 availability of oxygen at spawn depth. At Mill Creek, 

 California, the most feasible method for procuring this 

 information is by using the standpipe system. This paper 

 describes the design of the Mill Creek standpipe and its 

 method of operation, discusses the mechanics of seepage, 

 and compares the data obtained with data on the survival 

 of king Salmon spawn.
