Digitized edition from print [produced by Department of Fisheries and Oceans]. Includes bibliographical references (page 60). "The fisheries resource of Black Creek, a major coho salmon stream on Vancouver Island is described. Information on spawning escapement, distribution, and timing is provided. Hydrology of the 28 square mile watershed was studied using data from 16 staff gages and 3 water level recorders. The productivity of the system is attributed to the multiplicity of swamps, swampy depressions, and associated small tributaries characterizing the watershed which provide ideal habitat for rearing coho. Loss of this habitat occurs through swamp land reclamation and other land development activities. The extent of land development (logging, clearing, reclamation, ditching, and urbanization) in the watershed, and the detrimental effects on fish life is discussed. Recommendations for preservation of the fisheries resource are given. They include: restrictions on future water licences, reservation and development of storage, green strip reserves on all watercourses and swamps, suggestions on zoning and control of future land development"--Abstract.
