The San Cristobal River (Tagalog: Ilog ng San Cristobal) is a river system in Calamba City, Philippines. It is one of 21 major tributaries of Laguna de Bay.
Along with the San Juan River, it is one of the two major rivers that are the principal means by which Calamba's water drains into Laguna de Bay.[1]Its watershed area covers Calamba City and the municipality of municipality of Cabuyaoin Laguna, and Tagaytay City and the municipality of Silang in Cavite.[2]
The San Cristobal River forms Calamba's northern boundary, [1] with the other side of the river being the territory of the municipalities of with Silang, Cavite and Cabuyao, Laguna.[3]
Although a 1991 Study cited the San Pedro River and Morong River as the sources of eutrophication-causing minerals in Laguna de Bay, the Laguna Lake Development Authority (LLDA) has noted that more recent deterioration of the San Cristobal River (Calamba, Laguna) have made it one of the lake's major sources of nutrient loading. [4]
The LLDA's conservation efforts for the major tributaries and watersheds of Laguna de Bay have led to the creation of the Laguna de Bay River Basin Councils, of which the San Cristobal River Enhancement Defenders (SACRED) is particularly tasked with conservation of the San Cristobal.[5]
