1978 Map of Courtland

About this map

Merritt Island and Grand Island dominate this intricate look at the Sacramento River Delta, where the landscape is defined by a complex network of levees and waterways. The map illustrates the early 1970s character of small riverfront communities like Courtland and Locke, both significant for their historic architecture and role in the regional agricultural economy. Water management is central to the area's layout, with labels for numerous Pumping Stations, a Tide Gage, and the winding paths of Steamboat Slough and Sutter Slough.
