Oyama Lake (above) is one of Lake Country’s reservoir lakes, all of which are in multi-use watersheds. Lake Country Mayor James Baker (right) points to where the Oyama Lake Forest Service Road has been diverted away from this seasonal stream to prevent sediment from running into a tributary creek and the water intake. Jack Allingham, of Lake Country, (below, left) shows how close Oyama Lake is to being completely full and spilling this year as those on a watershed tour cross over at the spillway, Tuesday.
