Dicks Sporting Goods at Salmon Run Mall was closed Saturday following an early morning fire caused by an overheated light.
There was moderate fire damage to one of the racks and clothing, said town of Watertown Fire Chief Charlie Dillon, whose department responded to the 4:17 a.m. alarm call.
However, merchandise throughout the store sustained smoke and water damage, and the location remained closed as of Saturday evening.
Workers at the mall office and local Dicks store were unable to provide an estimated reopening and the Dicks corporate office was closed Saturday, but Chief Dillon said store officials initially hoped to open back up either today or Monday.
Their district manager was on scene really quick, he said.
The fire was caused when a ceiling light overheated, causing the contents of the ballast to leak into the light fixtures and create sparks that ignited a rack of clothing below it, Chief Dillon said.
Fortunately, the sprinkler system effectively contained the blaze until firefighters could extinguish it, he said.
It did what it was supposed to do, Chief Dillon said.
Sackets Harbor and Brownville firefighters also responded to the scene, as did the town of Watertown ambulance squad.
