The chalk streams have been intensively managed for many generations and in the twentieth and twenty first centuries, much of that management has been aimed at producing the best conditions for fly fishing and most specifically dry fly fishing. The chalk streams hold a good number of wild brown trout and grayling as well as stocked brown trout and stocked rainbow trout. The rich insect life and clear shallow water make the rivers particularly suited to fly fishing.
