High water mark

The river has been running high lately, as evidenced by the water level on the depth scale shown above. (This photo was taken yesterday.) The scale was painted on a pier of the Veterans Memorial Bridge in the mid to late 1990s and can be seen from Columbia River Park.  In the photo, the water level is almost at the 232 mark. At three notches above the water level, a faint "234" can be seen. The level during Hurricane Agnes (1972) is marked near the top of the scale at 241. Normal is at 227, which, of course, can't be seen here.
