2018 Map of Manor Slough

About this map

Antelope Valley and the western edge of the Sacramento Valley define this landscape where the inner Coast Range foothills meet the fertile floor of the Central Valley. The terrain transitions from the steep ridges and narrow draws of Long Canyon, Sulphur Gap, and Blanchard Valley in the west to a strictly managed agricultural grid in the east. This lower-lying ground is defined by a complex irrigation network, including the prominent Tehama Colusa Canal and Glenn-Colusa Canal, which divert water to sustain the region's ranching and farming operations. Local aviation history is represented by the Antelope Valley Ranch Airport, situated near the confluence of the hills and the plain. Natural drainage features such as Manor Slough and Freshwater Cr meander through the eastern flats, illustrating the historical hydrology of the basin before the extensive canal systems were established.
