Designated Uses

The designated uses of Chester Creek are:

• High Quality- Cold Water Fishery ( HQ-CWF): Rocky Run tributary of East Branch

• Cold Water Fishery (CWF): Green Creek tributary of West Branch

• Trout Stocking Fishery (TSF): East Branch of Chester Creek source to West Branch (except Goose Creek and Rocky Run), West Branch (except Green Creek), and main stem to Brookhaven boundary

• Warm Water Fishery (WWF) : Goose Creek tributary of East Branch and Main Branch south of Brookhaven border

The map on the Chester Creek home page illustrates these areas.  The High Quality designation is considered a special protection water. 

All of the streams in the Commonwealth of Pennsylvania have a designated use.  These include supporting aquatic life, as well as human uses such as fishing, water-related sports, and supplying potable water.  The objectives of Pennsylvania’s Clean Streams Law are: 

• Protecting these existing stream uses

• Bringing up to standards those stream segments which fail to support their designated uses
