The Delaware Estuary Comprehensive Study requests that the sub-committees of the Water Use Advisory Committee undertake as their initial task, the preparation of the first part of a report on the present and future use and needs of the organizations represented, relative to the waters in the estuary. The guide was prepared to simplify these tasks for the sub-committee members, and to assist members in eliciting responses from the organizations they represent. Part I of this guide briefly explains (1) the DECS and (2) the current quality and uses of the waters of the Delaware Estuary. Part II deals with ASSIGNMENTS. Part III contains certain reference materials that should be useful to all members of the four sub-committees.
