Forest Preserve District of Cook County 



1. Management and Development of Fishing Water s in the Cook County Forest Pre- 

 serves. 



The technical staff of the Forest Preserve District carry out fish population 

 surveys, various fish management activities and make the engineering plans for 

 the improvement of existing waters as well as for the construction of new ones. 

 Almost one-fourth of the State's fishing licenses are sold in Cook County and for 

 a large part of these anglers the impoundments and the 32-mile course of the 

 DesPlaines River through forest preserve holdings are the only waters available. 

 These are the most heavily fished waters in Illinois and, in terms of pounds per 

 acre, furnish some of the highest hook-and-line yields known.
