Cape Pond Brook and Mill River. 



Cape Pond, which forms the headwaters of Cape Pond Brook, 

 has been used since 1894 as a water supply for the town of 

 Rockport. Cape Pond Brook is an intermittent stream, flowing 

 in a westerly direction for 5 miles to empty into Mill Hirer, a 

 salt-water arm of the Annisquam River. The brook is ordi- 

 narily 4 to 5 feet wide, but when the level of the water in the 

 pond has been lowered, its upper channel becomes dry. Since 

 the old and young alewives imprisoned in the pond by the low 

 water during the summer and fall by dying polluted the water, 

 a dam was constructed below the outlet on Cape Pond Brook 

 to prevent their entrance. 



A public fishery, established in 1816 by Gloucester by placing 

 a number of spawning alewives in Cape Pond, was permanently 

 abandoned in 1894 when Rockport took Cape Pond as a water 

 supply. 



In spite of its natural advantages, which offer excellent op- 

 portunities, the fishery can never be re-established as long as 

 Cape Pond is used as a water supply. 



Danvers River. 



Danvers River, including Porter's, Crane's and Waters' 

 rivers, in the towns of Beverly, Danvers and Salem, is formed 

 by North and Proctor's rivers, Goldthwaite and Tapley 

 brooks, and receives as tributaries Beaver, Crane and Frost 

 Fish brooks. The river is obstructed by tide gates, and is 

 polluted by the waste products discharged chiefly from leather 

 factories. 



Although alewives were formerly caught at Sydney's Pond 

 on Tapley Brook, in Crane's River, and near the Peabody In- 

 stitute, the stream affords no present-day fishery, and within 

 the memory of the present generation, only a few alewives have 

 been taken. At the present time the fishery has passed be- 

 yond the possibility of reclamation, since all possible spawning 

 grounds on its course are used as water supplies, and tin- minor 

 streams serve mostlv as channels for manufacturing wastes.
