( CNN ) -- Flooding and resulting landslides killed 137 people Thursday and Friday in this nation 's northern provinces , including Baguio City , Benguet Province and Mountain Province , the Office of Civil Defense in Cordillera said Friday . A boatman transports three empty wooden coffins on the edge of Laguna Lake east of Manila on Thursday . Another 43 people were missing and 45 were injured , it said . Landslides blocked traffic along the Marchos Highway , Naguilian Road , Kennon Road and Ambuklao Road , cutting access to Baguio City , Benguet Province and Mountain Province , it said . The floods were unleased by tropical depression Parma , which had been downgraded from a typhoon . Earlier reports from Rocky Baraan , provincial administrator of Pangasinan , said flooding had inundated 32 towns and two cities , Dagupan and Urdaneta . Some 35,000 people had fled to evacuation centers , the official Philippines News Agency reported , citing the Provincial Disaster Coordinating Council . The worst-hit areas included Bayambang , Alcala and Basista , the news agency reported . People clambered onto rooftops as floodwaters rose , calling and texting for help . Rescue trucks were hampered by floodwaters that reach the roofs of single-story houses , Baraan said . About 16 rubber rescue boats had been deployed . Since the rains started in central Luzon , three dams in the Pangasinan area have been releasing vast amounts of water -- up to 10 million cubic meters per hour at one dam , dam officials said . Water passing through the three dams -- the Ambuklao , the Binga and the San Roque -- is rushing into the Agno River , which has been swollen since Thursday and affects seven towns in eastern Pangasinan , dam officials said . Water released from the San Roque dam has contributed to the flooding in eastern Pangasinan , acknowledged Alex Palada , division manager for flood forecasting and warning of the National Power Corporation . Dam officials had no choice but to maintain safe water levels , he added , noting that he alerted Pangasinan Governor Amado Espino . The governor started to evacuate residents Thursday when the Agno River started to rise , Palada said . In the last several days , water has become the Philippines ' biggest enemy , as Parma , locally known as `` Pepeng , '' dumped as much as 36 inches ( 91.4 centimeters ) of rain in some parts of the nation of islands , compounding misery in areas already flooded by earlier storm Ketsana . Parma was forecast to have winds of no greater than 39 mph ( 63 kph ) by Friday . The U.S. Navy was expected to join rescue operations in Pangasinan , according to the agency . Journalist Lilibeth Frondoso and CNN 's Judy Kwon contributed to this report .
