Lake Mainit
Definition
Lake Mainit is the fourth-largest lake in the Philippines, straddling the boundary of Surigao del Norte and Agusan del Sur provinces on northeastern Mindanao. Covering roughly 149 square kilometers, it drains through the Kalinawan River toward Surigao Strait and supports the fishing livelihoods of lakeside municipalities in both provinces.
The lake’s name derives from the Visayan word “mainit,” meaning hot, after the warm springs around its shores.

Examples and Analogies
Lake Mainit serves the Caraga region as Laguna de Oro’s northern counterpart: a border-straddling lake whose fish catch feeds lakeside towns and whose management requires two provinces to cooperate.
Usage Scenarios
Fishers work the lake for tilapia and native species; lakeside hot springs draw local visitors; the surrounding wetlands attract birdwatchers, and communities use the outflow river for irrigation and river transport.
Strategies
The Lake Mainit Development Authority coordinates the two provinces and lakeside municipalities on fisheries management, watershed protection, and pollution control under a joint development framework.
Security and Safety Measures
Lakeside communities observe flood advisories when heavy rain raises the lake level; fishers follow weather bulletins and boat safety requirements; hot spring areas post safety guidance for bathing.
Historical Context
The lake has long sustained Manobo and Mamanwa communities around its shores. Its management became formally bilateral when the two provinces created the joint development authority to address declining catches and watershed degradation.
Challenges and Controversies
Overfishing, siltation from upland mining and logging, and water hyacinth growth are the recurring resource management issues discussed between the provinces.
