Malinao Dam

Overview

Malinao Dam is a National Irrigation Administration (NIA) reservoir in Pilar, built in 1995 as part of Bohol’s provincial irrigation network. It is one of several dams the provincial government and NIA Region 7 monitor routinely alongside Bayongan (San Miguel), Capayas (Ubay), and Talibon. At full capacity the reservoir holds water to an elevation of 152 metres, with a critical spill threshold at 146.5 metres; as of one recent monitoring report the reservoir carried roughly 5.99 million cubic metres in storage, split between about 5 million cubic metres of active reservoir and 0.99 million cubic metres of dead reservoir that cannot be drawn down for irrigation. NIA has proposed an upgrade that would double active storage to 10 million cubic metres, extending irrigation to an estimated 2,730 additional hectares beyond what the dam already serves.

The same infrastructure carries real flood risk in heavy rain: in January 2023, a sudden 24-centimetre rise in water level within roughly two hours pushed the reservoir past its 146.5-metre critical spill mark, and NIA Central Visayas issued an evacuation advisory for residents along the Wahig River system downstream ahead of the spill. It is a working detail worth keeping in mind alongside the dam’s more commonly photographed picnic-spot side.

What’s there

Beyond its irrigation function, the reservoir and its banks are used informally for picnicking, short walks along the shoreline, and birdwatching, drawing on the vegetation around the water’s edge. There is no managed visitor facility — no ticket booth, no marked trail system, no staffed viewing area — so a visit here is self-guided in the way many working infrastructure sites doubling as scenic spots are across rural Bohol.

Location and getting there

The dam is within Pilar municipality, inland from the coastal poblacion described on Pilar’s own destination page. No source found pins the dam to a specific barangay or gives coordinates precise enough for the dam site itself, so coordinates are left unset here rather than approximated from the municipal centroid. One general travel-aggregator listing describes a route from the Chocolate Hills area southeast toward Loboc, then a turn at a Pilar junction for a further stretch to the dam — treat this as indicative only, since it comes from an aggregator site rather than an official source, and it separately (and almost certainly wrongly) describes the dam as a hydroelectric facility, which no NIA or provincial source supports. [FACT NEEDED: a verified route and distance from Pilar’s own poblacion, and the dam’s specific barangay/sitio.]

Practical info

No source confirms an entrance fee, gate hours, or staffed visitor facilities. [FACT NEEDED: current public-access status — whether NIA permits casual visitors onto dam grounds without prior clearance, given it is active irrigation infrastructure, not a designated tourist site.]

A Plus Code (“R8G5+J89”) and “hydroelectric power” claim appear on a general travel-aggregator page (evendo.com) but are not corroborated by any NIA, provincial, or news source, and the hydroelectric claim conflicts with every irrigation-focused source found — both are treated as unreliable and omitted.
