*NOTE: In 2008, storm damage impacted the roof and upper (third) rung of the Aquastore tank. The park issued a contract to demolish the top row (approximately 5’) of damaged glass fused sheets (reducing tank capacity from 54,000 to 36,000 gallons); install a new aluminum dome including one 30” x 30” roof hatch; and repair fillets on the lower two rows of tank sheets to ensure tank integrity. Interior and exterior ladders were salvaged.
