Why is Sandy such a bitch?

The Sandy River originates high on the slopes of Mt. Hood, located about 50 miles east of Portland, Oregon. The headwaters are beneath Reid and Sandy Glaciers at 6000 feet in elevation. (Hint: The water NEVER warms-up). 

From there the river flows due west through the Hoodland Corridor. It cascades past the communities of Welches, Brightwood, and Sandy, then turns north to enter the Columbia River near Troutdale, which is 10 miles east of Portland, Oregon.

The Sandy River is a geological product of the same dramatic forces that shaped the rest of the West Coast of North America. The river drops swiftly through rugged canyons. It has deep boulder-studded pools with clean, gray gravel bars often shaded by tall, wet green trees.

The character of the river is unpredictable. A few inches of water can change the holds. Twenty feet of water can change the whole river bed to the point that your favorite drift is now on the other side of the canyon.

The river bottom experiences terrific bed load shifts. Because of this, the aggregate never has a chance to compress and remains soft and very permeable.

Now that we have a history lesson about the river....why doesn't everyone know the history before they try to "walk or swim" across it? 

ANOTHER man is missing in the Sandy! This weekend claimed a 55-year-old man on a fishing trip (trying to walk on logs across the river...to get to a better spot). He slipped and was swept under the current...never to be seen again.  The Sandy River can be deceptively tranquil at first glance. A closer look, however, shows these currents are moving fast.

The missing man was wearing waders in the 48-degree water. Though waders keep an angler dry, the rubberized pants also quickly fill-up and drag someone down - like an anchor.

While its waters seem calm and gentle, there's a violent current that lies below the water's surface of the Sandy. We see it early in the Spring when the temperature first reaches 80-degrees...someone drowns. Later (every Summer) when the water reaches 54-degress...someone drowns.

Please people! Learn from history.
