Event Causes $10,000 in Damage to San Diego Landmark Ponds

San Diego, Calif., police are investigating a huge water-gun fight that left landmark lily ponds at Balboa Park trashed, bashed and partly drained, causing an estimated $10,000 in damage.

U-T San Diego says at least 1,500 people took part in the pre-dawn fight on Sunday that was organized on social media, including Facebook.

Organizers specifically urged participants to avoid the century-old lily ponds but authorities say some trampled new landscaping, killed koi fish, destroyed ornate floating Victorian lilies, broke a drain pipe and collapsed some planters.

No arrests have been made. U-T San Diego says organizers of the event are asking people to donate money to cover the damages.
