The following investigation was conducted by SA [REDACTED]
AT PORTLAND, OREGON
On February 20, 1980, [REDACTED] U. S. Army Corps of Engineers, Portland District, telephone [REDACTED] was contacted regarding the possibility that bait money found near the [REDACTED] on February 10, 1980, could have been brought to that area by a river feeding the Columbia River from the north.
The area believed to be the drop zone of the subject in 1971, is described as that area in the State of Washington bounded on the north by the Lewis River, the east by the Clark County-Skamania County line, and the Columbia River. [REDACTED] advised the only likely river feeding the Columbia River within the above described drop zone that would be capable of moving several bundles of money or a package about 16x16x4 inches to the Columbia River would be the Washougal River. A logical time, if the money came down the Washougal, would have been during the December 2, 1977 Washougal flood when parts of the river were approximately ten feet over the normal winter flood stage.
There are several other streams that feed the Columbia River upstream from the [REDACTED] however, due to size, or the degree of slope of the streams, it is unlikely that a small package would have made it to the Columbia. It is also unlikely that a small package would have passed through Lacamas Lake downstream to the Columbia.
[REDACTED] stated that based on the three feet per second speed of the Columbia River, if a small package entered the Columbia River at Washougal, Washington, and floated in the main stream of the river to the [REDACTED] a distance approximately thirty miles, it would take 14.7 hours. This is assuming that the package did not tumble along the bottom of the river or get caught on any snags.

[REDACTED] stated that numerous streams feed the Columbia downstream from the [REDACTED] including the Lewis River which would move a small package to the Columbia; however, it is not possible that it would move upstream to the area the money was located.

[REDACTED] provided a topographical map which includes the above described area.
