More re "shore":
By coincidence I recently edited a legal title on Waters and Watercourses, and came across the idea that, in the English common law, the term "shore" refers only to tidal waters, while in North America the term was expanded to include freshwater lakes as well. (My Oxford Concise English Dictionary only partly bears this out: "Law. the land between ordinary higgh- and low-water marks.")
Is this a legalistic idea which isn't reflected in common speench in England (and is the river tidal at Walker Shore)? If not, what would a lakeshore be called in England?
