Abstract
3D-Modeling of Steelhead/Rainbow Trout Passage in Southern Santa Barbara County
Track: Forestry, Wildlife, and Fisheries Management
Author(s): Timothy Robinson
3D Analyst in conjunction with a developed multi-purpose GIS-database were used to study southern steelhead (Oncorhynchus mykiss) stream passage and sediment transport through three creeks in southern Santa Barbara County; Quiota and El Jaro creeks, tributaries of the Santa Ynez River, and Mission Creek, City of Santa Barbara. Hydraulic and fish passage design/engineering were evaluated in HEC-GeoRAS. Southern steelhead were federally listed endangered species in 1997, hence requiring careful analyses of any riparian corridor projects within designated critical habitat. Swim-through (fly-through) imagery will be presented as well as completed and proposed projects on those creeks. Mission Creek is considered to be the most viable steelhead stream within the City of Santa Barbara and tributaries of the Lower Santa Ynez River below Lake Cachuma are well known for spawning and rearing of steelhead. The stream restoration projects presented will directly benefit the National Marine Fishery Service’s southern steelhead recovery planning effort.
