The Skagit Riverwalk serves several purposes. Besides being a beautiful way to enjoy the majestic Skagit River, it's a functional part of the flood control system. As you walk, take note of the openings in the brick walls. You'll see metal plates on the ground, and slots with gaskets at each side of the opening. In the past, during flood season, hundreds of volunteers would arrive here and fill thousands upon thousands of sand bags to make a dike to protect Historic Downtown. This would be a 12-24 hour job. Now, a crew of 8 brings custom containers designed to be hauled by the city's sanitation trucks. These containers are filled with panels and braces that fill these wall openings. What took hundreds of people to do in a 12 hour period, is now done by 8 workers in about 4 hours.
At the northern stop of this multi cache, you will find some information that is critical at the end. Take a moment here to look around. Check under the bridge for the Log Jam Memorial. A fine tribute to the men who cleared this river 100+ years ago (The info you are looking for is NOT on the Log Jam Memorial.
