Popular gift card purveyor Blue River Canyon Day Spa in Brentwood this week filed for Chapter 11 bankruptcy in U.S. Bankruptcy Court.

According to the filings, Blue River Canyon Inc. owes more than $680,000 to its largest creditors. The largest of those is Pinnacle National Bank, which lent Blue River Canyon more than $380,000. The spa also owes $123,587 to local, state and federal tax agencies.

Court documents show Blue River Canyon had revenues of more than $1.2 million in the last year — down from $1.4 million in 2010 — but that officials expect to incur an average net monthly income deficit of $1,382. View the company’s filing here.

Blue River Canyon Day Spa opened in 1998 and is based on Thoroughbred Lane in Maryland Farms.

A call Thursday to Steven Lefkovitz, the attorney for Blue River Canyon president Bradley Slavik, was not returned.
