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.
