This amendment provided that the Commission on Water Resource Management (CWRM) “identify rivers or streams, or a portion of a river or stream, which appropriately may be placed within a wild and scenic rivers system, to be preserved and protected as part of the public trust ... the term ‘wild and scenic rivers’ means rivers or streams, or a portion of a river or stream, of high natural quality or that possess significant scenic value...” The Hawaii Stream Assessment (HSA) was made possible through the support of the National Park Service’s River and Trails Conservation Assistance Program. Additional support was providedby the DLNR’s Division of Water Resource Management, includ ing funding for the Hawaii Heritage Program’s development of the aquatic database. The report and its findings and the supporting database of information were prepared by the HSA Study Team which represented the Hawaii State Department of Land and Natural Resources and the US. National Park Service with the assistance of committees of experts representing federal and state agencies and private organizations. Streams were inventoried and then assessed for their values in four resource areas aquatic, riparian, cultural and recreation. These areas cover the beneficial instream uses defined in the State Water Code with the exception ofnavigation and the protection of traditional and customary Hawaiian rights. While the original intent was to also include important offstream uses, sufficient and verified information was not available in time for this study. it is our understanding that the State Commission on Water Resource Management will consider these missing elements along with the information in this report when making management decisions. In the judgement of the study team, the existing information, while limited, was sufficient to conclude that the state’s surface water resources are limited, fragile, and in need of protective management now. The Water Commission suggested alternatives for a wild and scenic river system be developed. It is important to note that, while alterna tives and recommendations are provided, this study does not initiate any action, protec tion, designation or zoning changes. The draft report was presented for public comment in September 1990. Public participation was lively, extensive and substantive, and the final report was revised to reflect these comments and concerns. m We hope the Hawaii Stream Assessment will help provide an overview of Hawaii’s surface water resources, allowing the evaluation of any given proposal to take place within a statewide context. This final report and the database are submitted to the Water Commission for its use in future decisions about the management of Hawaii’s perennial streams. Dr. Clifford W. Smith, Director Cooperative National Parks Resources Studies Unit University of Hawali Carol Wilcox, Project Coordinator Department of Land and Natural Resources State of Hawaii Sallie Edmunds, Project Coordinator Cooperative National Parks Resources Studies Unit University of Hawaii lv Acknowledgements T0 all those who in any manner contributed to the Hawaii Stream Assessment, the authors express their sincere thanks. But, as always in projects of this magnitude, certain individuals contributed far beyond the original commitment. Audrey Newman and Patty Kupchak provided the opportunity for extensive discussion and debate, as well as review and comment. Meredith Ching reminded us of the economic importance of streams. Luciana Honigman prepared the aquatic resource inventory data and bibliography. Maps and many of the tables were developed by Jane Lewis. Simon Chan did much of the data entry later assisted by Billy Tabuio. Susana Chang and Datta Bhanibare performed various desktop publishing tasks. Patricia Tummons assisted with editing. Sherrie Samuels was invaluable as primaiy DU4R contact. Martha Crucius and Drew Parkin contributed a national perspective of river assessments. Cooperation was the key to the Hawaii StreamAssessment. The strengths of this report are due to the participation by many in government and the private sector. Individuals from Hawaii’s state government departments of Land and Natural Resources, Business and Economic Development, and Health; from federal agencies including the U.S. National Park Service, Geological Survey, Army Corps of Engineers, Fish and Wildlife Service; County plpnning and public works departments; the professional and business community, in particular The Nature Conservancy Hawaii; and the University commu nity were all unfailingly generous with their time, expertise and patience. Fmaliy, none of this would have happened without the support of the water commis sioners, ChairmanWilliam Paty, Michael Chun, Richard Cox Guy Fujimura, John Lewin and Robert Nakata. The Commission on Water Resource Management and the Depart ment of Land and Natural Resources, the primary managers of the state’s natural resources, recognized the importance of an inventory and assessment of surface water resources for informed decision-making. The commissioning of this independent proj ect, with its conservation point of view, is an indication oftheir commitment to long-term care of Hawaii’s natural resources. The authors are grateful to all of the project participants listed on the following pages who made the Hawaii Stream Assessment possible...this is your work.
