Hey Hot Rod,

Yes, they did drain the lake because they had to reshape it. All told, they removed over 2,000 fish - both game fish and koi. Most of the game fish were relocated to other parks waters, including the Oklahoma River. The Koi are being safely kept in another park location where they are being watched over by staff, as well as members of the City's municipal fish hatchery. They will be relocated back to the Gardens when the bulk of construction around the area is completed and the waters there are deemed ready. I'm not really sure when that will be, or if it will be by the opening. They want to make sure the waters are habitable and sometimes it takes a while to get the balance right, even for a "natural" pond.
