1912 Map of Tisdale Weir

About this map

The Sacramento River carves a winding path through this 1912 survey, marking the boundary between Colusa and Sutter Counties. The landscape is dominated by the flood-prone expanses of the Sutter Basin and Colusa Basin, where a network of water bodies like Mc Intyre Lake and Long Lake punctuate the marshy terrain. The presence of the Tisdale Weir indicates early twentieth-century efforts to manage the river's overflow into the surrounding lowlands.
