In 1925, Great Western Power Company announced its plans to enlarge Lake Almanor. The raising of the dam would flood a large portion of Chester Flats, thus flooding a number of roads, and also Red River Lumber Company logging railroad network. Controversy arose when Great Western informed the Plumas County Board of Supervisors that the road across Chester Flats would be re-routed to follow the high water contour. The residents of Chester and Westwood were furious, for such a proposal would add an additional seven miles between the two communities. They wanted a causeway in which the current route would remain the same. Great Western balked at the idea. After all, a causeway would cost Great Western $220,00, while to re-route the road would only cost $50,000. To make a long story short the opponents bypassed the Plumas County Board of Supervisors and had the State Highway Department intervene. In 1926, an agreement was made between the State and Great Western that a causeway would be constructed.
