the national park service used arra funds and actually rebuilt the whole thing during the obama administration. and when they had an algae problem, shortly after it being filled back up... they fixed that for a measly $100 thousand to drain and clean it all, and then increased the ozone used in the filtering system to control the algae.

it should cost less than $150 thousand to completely drain and clean it today. note there's no "millions" here.. not even a single "million". just one hundred and fifty thousand. anything more than that is taxpayer money being stuffed in to someone's pocket.
