Air carrier flight crew was informed after the fact that they landed on unmaintained runway 2 at yak...

Narrative:

We were on final approach for a daytime landing to yak (paya). Upon arrival into the airport area; we determined via radio communications with another aircraft in the pattern that the active runway in use was runway 2. Additionally; the ASOS report indicated a wind between 5 and 10 KTS that favored runway 2 and temperatures well above freezing. The other aircraft ahead of us was using runway 2. There were no NOTAMS regarding any closures or restrictions on runway 2. I performed an uneventful landing on runway 2 followed by a taxi to the gate via taxiway B. The captain received a phone call from our base chief pilot notifying us of the event.apparently we had used a runway and taxiway that were 'unmaintained' october 1 through may 1. There were no NOTAMS in the flight paperwork stating this. Additionally; on the airport diagram it only states that taxiway B; C; and D are unmaintained october 1 through may 1. It states nothing about runway 2/20. It is only found in an obscure note on our company provided airport briefing material that runway 2/20 is 'unmaintained' october 1 through may 1. Provide guidance of unmaintained runways and taxiways via NOTAM. In addition; provide this information on the airport diagrams.
