Officers believe a dog walker was in the area at the time she went missing.
Inspector Craig Nicolson said: “You can expect to see our police marine unit, helicopter search teams supported by the coastguard, Nith Inshore Rescue and mountain rescue teams in the area.
“We also have detectives checking CCTV to find any clues where she may have gone.
“We know from CCTV a man is seen walking two small dogs along Mill Road towards Market Square at around 3.15am on Sunday morning and we want to speak to this man.”
