Note: Seepage from channel out of SDH -3U is low enough to not lepardise the embankment. Minimal downcutting was
observed and it remains stable. Plans are to continue watching this area and repair with chip bentonite if conditions worsen.
Otherwise, repairs will occur in the Spring once the ground thaws.
