The Sumas River watershed is an economically important agricultural area located within the Lower Mainland area of the Fraser River basin. In 1991, the gross farm revenues were greater than 68 million dollars with expenses greater than 53.5 million. This watershed was selected as the study area. The goals of the study were to: (1) identify farms which followed the Code of Agricultural Practice for Waste Management and Agricultural Environmental Guidelines and (2) identify possible contaminant sources which could impact water quality. An inventory of the agrowaste facilities and management in the Sumas River watershed was carried out. This inventory included completing a telephone questionnaire followed by a farm visit - a process that should be updated within five years to document changes. The surface water quality was studied over a five month period and five fish species composition and relative abundance studies were conducted.
