Lake River
Lake River, a "slow, flat slough of the Columbia River", loses only 1 foot (30 cm) in elevation over its entire 11-mile (18 km) course. It flows north, roughly parallel to the Columbia until curving slightly northwest to join it. At times, tidal fluctuations and high flows along the Columbia cause Lake River to flow backwards into the lake, sometimes for long periods.
