Narrative:
10 mi south of real county airport while en route from uvalde, tx, to leakey, tx, partial power loss occurred, resulting in inability to maintain altitude (descent was begun). I had to fly about 200' AGL over the town on approach. After landing, I drained about 1 qt of H20 from each main tank, after which engine ran perfectly. No H20 was discovered on preflight. Suspect it had been there a while. Aircraft now runs fine. Aircraft was last refueled at FBO in san antonio, but their fuel has never been a problem before. Sumps were drained after last refueling and prior to flight. Aircraft parked outside on several occasions at different airports.

Title: GA SMA INVOLVED IN LOW FLT OVER POPULATED AREA WHILE MAKING A FORCED LNDG DUE TO FUEL CONTAMINATION.
Narrative: 10 MI S OF REAL COUNTY ARPT WHILE ENRTE FROM UVALDE, TX, TO LEAKEY, TX, PARTIAL PWR LOSS OCCURRED, RESULTING IN INABILITY TO MAINTAIN ALT (DSCNT WAS BEGUN). I HAD TO FLY ABOUT 200' AGL OVER THE TOWN ON APCH. AFTER LNDG, I DRAINED ABOUT 1 QT OF H20 FROM EACH MAIN TANK, AFTER WHICH ENG RAN PERFECTLY. NO H20 WAS DISCOVERED ON PREFLT. SUSPECT IT HAD BEEN THERE A WHILE. ACFT NOW RUNS FINE. ACFT WAS LAST REFUELED AT FBO IN SAN ANTONIO, BUT THEIR FUEL HAS NEVER BEEN A PROB BEFORE. SUMPS WERE DRAINED AFTER LAST REFUELING AND PRIOR TO FLT. ACFT PARKED OUTSIDE ON SEVERAL OCCASIONS AT DIFFERENT ARPTS.
