is 5 miles, and of the conduit from the Stubden reservoir to the Bond Clough 

 at Haworth, the most distant stream taken to the west, 4 miles. 



The whole of the works so far mentioned are exclusively for collecting and 

 supplying water for the use of the towns. 



Other reservoirs with separate drainage-areas have been made for collecting 

 and supplying compensation water to the various mills and streams which are 

 affected by the taking of the town supply — viz. the Gumwith reservoir at 

 Hartlington for giving compensation water for that which is taken from the 

 streams in the valley of the river Wharfe, the SUsden reservoir at Silsden for 

 the low-level works in the valley of the river Aire, the Hewenden reservoir at 

 Hewenden for the old supply of the Many "Wells spring, the Doe-Park reservoir 

 at Denholme for the high-level works in the Denholme valley, and the Leeming 

 and Leeshaw reservoirs at Oxenhope (now in course of construction) for the 

 streams to be taken in the vaUey of the river "Worth. 



The extent, capacity, &c. of the several reservoirs are as follows, viz. : —
