Abstract

Preparation of this guidance manual for integrated aquatic vegetation management in irrigation canals was stimulated, in large part, by the accidental release of acrolein-treated irrigation water into Bear Creek in southern Oregon. The resulting fish kill brought into focus the need to examine the methods available for managing aquatic vegetation in flowing water. Furthermore, it demonstrated the need for technical assistance on aquatic vegetation management in Oregon. Vegetation management in flowing water is a difficult undertaking. The interconnectedness of natural and manmade water conveyance systems, the tenuous status of many aquatic species, and the necessity of water delivery for profitable and productive agriculture in Oregon and much of the Northwest interact to focus attention on the way that aquatic vegetation management is conducted. Endangerment of fish species in the Pacific Northwest requires a detailed examination of agricultural operations. This manual is intended to provide water conveyance system managers a summary of available technologies for aquatic vegetation management and to outline the concepts and procedures necessary for development of an integrated management plan for vegetation growing in canals. With the adoption of a thoughtful approach to aquatic vegetation management, and with technical assistance and research on the problem plants and control techniques, aquatic vegetation can be managed without severe off-site and non-target impacts. It is hoped that this manual will assist in reaching that goal.
