Narrative:

I had a close call with an aircraft while on landing approach to runway 3 at ZZZ. We (aircraft X) were on about ½ mile final. I looked around and spotted aircraft Y about 100 feet below and 50 feet in front of me. I made an immediate turn to the right and made a go around. I heard aircraft Y's pilot call entering the [area] at 4500 feet (which was at least 20 miles ahead of me) enroute to ZZZ. A short time later; I heard aircraft Z called [inbound] for ZZZ. When I was about 25 miles from ZZZ; I heard aircraft Z call a 5 mile final for runway 3 at ZZZ. Then aircraft Y's pilot called about the same distance and said he could see aircraft Z and would circle for spacing so aircraft Z could land.at 20 miles out; I called unicom; got weather and information regarding aircraft Z landing and the aircraft Y in front of me; and another aircraft on the ramp holding for landing traffic. When I was 10 miles out; I heard the aircraft Y call final and assumed he was within 5 miles of the runway. I maneuvered for a 5 mile final and slowed to 120 knots IAS approach speed and did not see or hear the landing aircraft Y until I was told the landing planes were close. When I did spot him; I said; 'I am above you and will circle so that he could land and the flight holdings could depart.' aircraft Y was white and blended in with the snow in the background so it was difficult to see.conclusion we both should have made more position reports regarding altitude; distance; and position from runway reports. If we had TCAS; it would certainly have made a difference.
