Concrete weir box and takeout from a concrete flume. (Fig. 10). 



This box is used on some of the irrigation systems of southern California 

 for takeouts from concrete flumes. The form of construction is equally 

 well adapted to takeouts from wooden flumes or concrete lined canals. The 

 flow is regulated by wooden gates which control the flow in the canal and 

 in the weir box. To form a still body of water in the box grooves are pro- 

 vided for the insertion of baffle boards. The water which passes over the 

 weir discharges into the private flume of the orchardist.
