A Water Quality Baseline Inventory of Fort Clatsop National Memorial was initiated in September of 1995. Sites included in this inventory included the Lewis and Clark River, 2 permanent streams, 1 ephemeral stream, 2 ephemeral springs, 3 ephemeral ponds and 1 slough. All sites were sampled 3 times per month throughout the year, in the case of the ephemeral sites until they dried up in the summer and beginning again in the fall when the water returned.

The average American man in the early 1800s was 5'5" or 5'6". Both Clark and Lewis were six feet tall though. Under most circumstances military recruits had to be at least 5'4" to join the army.
