Weir 1 Final Project Report+Appendices_Part2.pdf

This is a map document from a feasibility study showing the Sutter National Wildlife Refuge and surrounding wetland location in California. The map depicts the study area for the Butte Creek - Sutter Bypass Weir 1 Feasibility Study and Alternatives Analysis, sourced from ESA in 2024. The geographic area includes portions near Joesphine and Tisdale, California, with Weir 1 prominently marked as the central project location.

The map uses color-coded legend indicators to identify various water features and land classifications including freshwater emergent wetlands (bright green), freshwater forested/shrub wetlands (dark green), freshwater ponds (light blue), lakes (dark blue), riverine areas (cyan), levees (purple), refuge conveyance waterways (blue lines), Sutter Bypass areas (light gray), and SNWR (snow white/empty areas). The visualization illustrates the complex hydrology and ecological features of the Sutter National Wildlife Refuge area, showing the spatial relationship between the bypass infrastructure, wetland habitats, and surrounding agricultural lands represented in various states of cultivation and fallow conditions.
