Abstract : The following mechanical and physical systems should be employed at various locations throughout the Delta. Because mechanical control is the most site-sensitive method, the specific locations of some of the recommended systems cannot be determined without additional site analysis. It is recommended that: A. Boom assemblies be designed and emplaced at selected marines. B. Pusher boats and conveyors be used inside the marina to remove the existing plants remaining after initial installation of boom systems. C. Small capacity harvesters and/or boom systems be strategically located in the main Delta waterways to minimize the redistribution of existing plant infestations. D. Large mechanical harvesters be used only after analytical evaluation of performance and cost have been conducted. E. Where feasible, plants be chopped (mowed) in place and left in the waterway. F. For water intake structures, small gridded fences and/or booms be installed in low flow areas.
