The project consists of the selective removal of both native and non-native riparian species within Dead Horse Slough, Little Dead Horse Slough, Upper Lake, and the Lower Lake. Vegetation removal would target non-native species such as privet, vervain, seedling mulberry, tallow etc. Natives would include cattail, seedling willow, cottonwood, and alder. Removal of vegetation would include the use of herbicides registered for use in riparian habitats. The herbicides would be used under a licensed pest control advisor (PCA). Cattail spraying operations would conform to California Park’s National Pollutant Discharge Elimination System (NPDES) permit and an Aquatic Pesticide Application Plan (APAP) with monitoring and would be performed 3-4 times a year. Herbicide use would be performed by a licensed pest control operator (PCO) with a PCA recommendation and within all label mandates. Within Dead Horse Slough and Little Dead Horse Slough, vegetation will be removed in the channel that prohibits regular stream flow. Trees greater than 4 inches DBH will be retained but may be limbed up. Additional riparian vegetation that is not prohibiting flow will be retained as well.
