I wouldn't be surprised if the park service shuts down the regatta altogether this year. I m pretty sure the official regatta finishes in park water and requires a permit. As to the party, held separately from the official regatta, considering the amount of planning it takes, with all special markers and buoys, the barge, etc... I don't see it happening either as they have shut down all tours and fishing guide operation in the park. It that s the case, the party will likely end up at the KB sandbar...
