When in Doubt, Stay Out! The Wisconsin Department of Natural Resources has confirmed the presence of blue-green algae in Lake Petenwell, Castle Rock Lake, Lake Sherwood, Lake Camelot, and Lake Arrowhead in Adams County. Illnesses in humans and animals potentially related to blue-green algae in these lakes have been reported as well.
The Battle of the Eureka Stockade, by which the rebellion is popularly known, was fought between miners and the Colonial forces of Australia on 3 December 1854 at Eureka Lead and named for the stockade structure erected by miners during the conflict.
In August of 1769, a destructive native attack and the threat of future conflict forced the Spaniards to erect a crude stockade on Presidio Hill. Completed in 1770, the presidio protected the mission and the colony, and further represented a permanent Spanish presence on the bay. The original presidio was simply made and constructed entirely of wood. The fenced stockade included two bronze cannon and rough wooden houses with tule roofs.
