New estimates indicate that flooding at the Weston Playhouse will cause between $100,000 and $200,000 in damages.

Fears about Hurricane Irene may have shuttered Broadway this weekend, but the worst havoc to a theater occurred roughly 230 miles to the north in flood-ravaged Vermont. The Weston Playhouse, which is celebrating its 75th season this summer, was overrun on Sunday with between 6 and 12 feet of water in the orchestra pit, prop shop, dressing rooms and other parts of the lower levels of the theater, causing $100,000 in damage and upending the schedule for its new musical, “Saint-Ex.”

Steve Stettler, one of the producing directors of the playhouse, said on Monday in a telephone interview that no company members were injured during the storm; the calamities mostly befell the physical production of “Saint-Ex,” a world premiere about the French aviator Antoine de Saint-Exupéry (best known as the author of “The Little Prince”).

All the show’s costumes were in the flooded dressing rooms, which were still being emptied of water on Monday afternoon. The grand piano used for the show was destroyed in the pit, which is unusable for now. The piano had been a gift to the theater, valued in the tens of thousands of dollars, Mr. Stettler said.

“Saint-Ex,” which began its run on Thursday and opened on Friday, has canceled performances for the next several days while theater company members finish pumping water from the building, cleaning out the leftover mud and muck, and inspecting conditions. Beginning this Friday night, Mr. Stettler said, “Saint-Ex” will resume as a concert production. The 11-member cast will perform out of costume with simplified lighting and design effects, and the five-person band will perform on stage alongside them.

“Right now our focus is taking care of people who got flooded out of company housing and figuring out the extent of the losses in the building,” Mr. Stettler said. “We’ll have time to rehearse the musicians and actors in the next couple of days for a concert staging. This was a beautiful production — we were getting standing O’s every night — but the essence is the actors and the story, and we’ll still be able to present that.” The musical will conclude its run on Sept. 10 as previously scheduled.

The overflow from the West River, which runs close by the theater, was the worst since a 1973 flood that is widely remembered in town, Mr. Stettler said. Sunday’s storm caught him and others relatively unprepared. By the time the threat of flooding was obvious on Sunday there was only time to move some expensive rental equipment out of the cellar. “There was no time to get the costumes or the grand piano,” he said.

Neither the theater company, which has an annual budget of $1.6 million, nor the playhouse’s landlord has flood insurance because it was too expensive to buy, Mr. Stettler said. The orchestra pit, which was built this year for the 75th anniversary, will either be refurbished or reconstructed, depending on the extent of the damage.

“Right now we just need to get all the water out,” he said. “And then we’ll assess what shape we’re in.”
