Just before leveling at 8;000 FT the First Officer noticed the Number 1 oil temperature was at the upper limit. We monitored the temperature and started timing when it exceeded 115. I notified ATC that we had a problem and they gave us vectors to shorten the route. We reduced power on the engine and noticed the temperature decreased slightly below 115. We continued to destination and declared an emergency to get expedited handling. The temperature had decreased to about 110 during the descent; and was within limits as long as we didn't exceed 60% torque. The total time the oil temperature was above 115 was 18 minutes. The landing was made without further incident.
DHC8-100 Captain experiences high oil temperature during descent for landing. Torque is reduced on that engine and the flight is able to continue to destination and land with the oil temperature below the red line.
