Narrative:
#1 hydraulic low pressure light came on in-flight followed by loss of fluid indications. Performed procedure, called dispatch and maintenance. Continued on to oak, declared emergency and landed normally. Had fire crew check aircraft over. They said fluid was leaking and some tire tread damage, but tire was still inflated. Got to gate and called air carrier. He said departure airport tower had shut down runway for rubber on runway. ATC told air carrier they weren't sure what flight it was, but thought it was the flight to ZZZ. Air carrier informed that at hotel. Called air carrier and it turns out the tower logged the rubber problem around our departure time which made it our flight. Had air carrier known the correct time earlier, they would have notified us and we could have dealt with it differently. Supplemental information from acn 616269: had we known this information en route, we would have known the tire had caused the hydraulic failure and could have returned to departure airport.
