i12 Flood Bypasses 2014
This feature class is a vector file containing polygons that represent the flood control bypasses of the Sacramento and San Joaquin Rivers. Bypasses convey excess flood waters from rivers and streams onto designated lands to reduce flood risks to populated areas. It combines polygons the capacity coverage (which follows CLD Levee centerlines) from GEI Consutlants, Flood Project Inspection and Integrity Branch (FPIIB) capacity coverage, digitized areas from 2005 NAIP (Butte Basin and Butte Slough), and polygons digitized by Michael Ward -- SJR Bypasses (Eastside, Chowchilla Canal, and Mariposa).20141015: The parent bypass layer was compiled by DWR, Northern Region Office using data supplied by various sources, as stated in the metadata, which is for display purposes in maps. The Yolo Bypass polygon has been substituted for the polygon developed by MWH Global Inc. in 2012 and was modified to more closely match previously reported acreages. The primary modifications are: 1) Removal of the Sacramento River Deep Water Channel 2) The west side of the bypass was modified to match the Central Valley Flood Protection Plan (CVFPP) economic impact dated 20110826 areas from Putah Creek to the end of the western levee. This layer was used in the CVFPP 2017 Update.20210107: Prospect Island was added from parent file Delta_Islands_20140616.shp. It is not a legal boundary and is for representation only.
