Huai Chorakhe Mak Reservoir is an inland freshwater wetland in Mueang Buri Ram District and Sakae Phrong Subdistrict, Buri Ram Province, northeastern Thailand. Created in the mid-1970s by damming several small streams on an extensive floodplain, the site comprises open-water reservoirs with limited emergent or floating vegetation, surrounded by predominantly rice-based agricultural landscapes and small patches of dry dipterocarp woodland. The reservoir is publicly owned and designated as a Non-Hunting Area under the Department of Wildlife and National Parks, with the Wetland and Sarus Crane Conservation Centre serving as the management and awareness hub for the site.

Huai Chorakhe Mak forms part of a nationally significant wetland complex, together with Huai Talad and Sanam Bin, that supports the successful reintroduction programme for the globally threatened eastern population of the Sarus Crane. The site also supports congregations of freshwater-dependent waterbirds and provides essential ecosystem services, including water storage, food provision, flood hazard regulation, and cultural services linked to education and nature-based tourism. However, pressures from agricultural intensification, invasive species, climate-induced drought risk, and expanding tourism infrastructure pose challenges to long-term sustainability. Strengthening site management and protection, sustaining crane and biodiversity monitoring, improving invasive species management, promoting biodiversity-friendly rice farming, and enhancing low-impact ecotourism offer key opportunities to reinforce livelihoods while safeguarding the ecological integrity of this important inland wetland.
