. Historically, recreational activities on the lake in the wetland complex included fishing and ice skating. In July 1936, high temperatures caused stagnant water and gases to kill approximately a thousand carp and catfish in the Espy Bog. No evidence of pollution was found. The Espy Bog is listed as a locally significant area on the Columbia County Natural Areas Inventory.
