The helicopter with four crew members on board crashed into the Erhai Lake at 10:20 a.m. as it was attempting to draw water to clear and irrigate a burnt area caused by a forest fire, said the information office of the Dali municipal government.
Two crew members were retrieved at around 11:40 a.m. and 3:15 p.m., respectively, but died despite emergency medical treatment, it said.
Over 490 professional rescue workers with 16 rescue boats have joined the search operation for the missing crew members.
