Del Rio is found in the southeastern corner of Glenn County just south of Llano Seco Rancho. The project site is approximately five miles north of Butte City and one mile east of the Sacramento River at River Mile 175L.
Del Rio occupies flood-prone land between the Sacramento River Flood Control Project setback levee and Angel Slough.
The original topography of Del Rio was obliterated with land leveling for agriculture. East of the restoration site is a ridge, and then the western branch of Angel Slough, which follows the western edge of an uplifted basin within the Sacramento River floodplain. Towards the river to the west, lies the higher ground of the natural levees and the East-Side levee of the Sacramento River Flood Control Project. During flood events, water flows out of the Sacramento River and into the Butte Basin. The former almond orchard is observed to flood every 4-5 years.
Vegetation on the former almond orchard is typical of fallow farmland. Non-natives, such as black mustard, dandelion, mayweed, sow thistle, aster, and a variety of grasses (wild oats, Johnson grass, Bermuda grass, and annual ryegrass), are common. Vegetation to the north and east are managed for conservation purposes. The conservation easement to the north may be planted to native species in the future, but is currently dominated with non-native annual grasses. Some cottonwood and oaks have colonized areas near swales. The managed wetlands to the east contain willows, smartweed, cattails, and other wetland indicative species. Orchard and row crops occupy lands to the south and west. The Del Rio site is contiguous with nearly 12,000 acres of wildlife conservation habitat on the former Llano Seco Rancho managed by the US Fish and Wildlife Service, The Nature Conservancy, and the California Department of Fish and Game. Species of special concern that are either present or potentially occurring at Del Rio include Bald eagle, Black headed grosbeak, Least Bell’s vireo, Sandhill crane, Swainson’s hawk, Willow flycatcher, Yellow-billed cuckoo, Wood duck, Valley elderberry longhorn beetle, Sacramento Splittail, Chinook salmon, and Giant garter snake.
Current Land Use
Del Rio is divided into three sections: 1) existing riparian habitat (27 acres), 2) walnut orchard (136 acres), and 3) former almond orchard (96 acres).
Adjacent Land Use
Adjacent properties to the north and east are private lands protected by conservation easements managed for wildlife or owned by the US Fish and Wildlife Service. The prune orchards and crop fields to the south are privately owned.
The only access to the Del Rio project site is via a semi-public paved road (Road 50).
