BUILDING MAN-MADE LAKES IN BARANGAYS

BUILDING MAN-MADE LAKES IN BARANGAYS In the Philippines, Republic Act No. 6716 mandates the construction of water wells, rainwater collectors, and the development of springs in all barangays. This law was originally enacted to prepare communities for El Niño, a climatic phenomenon that brings dry spells and droughts, often affecting water supply and agricultural productivity. However, I firmly believe that this initiative can be taken further to maximize its benefits beyond just water conservation. If properly designed, these water embankments could be constructed in a way that transforms them into man-made lakes. These lakes would not only serve as water reservoirs but could also play a crucial role in flood control, aquaculture, food production, and even energy generation. Expanding the Purpose of Water Retention Ponds 1. Support for Aquaculture and Livelihoods – Instead of just acting as water storage, these lakes could be used for fish farming, providing an additional source of livelihood and improving food security in barangays. 2. Growing Water Vegetables – Certain vegetables thrive in wet environments, such as water spinach (kangkong), taro (gabi), and watercress. These crops could be cultivated around the lakes to further enhance food supply. 3. Drinking Water Source – With the use of affordable water heating and filtration technologies, the water collected in these artificial lakes could be made potable, addressing the persistent issue of clean water shortages in many areas. 4. Potential for Hydropower Generation – Small-scale hydropower technology could be explored to generate energy from water movement in larger lakes. 5. Rainwater Collection Integration – By connecting rooftop rainwater collection systems to these lakes, barangays could significantly increase water retention capacity and improve overall water management. 6. Irrigation Support – Farmers in surrounding communities could use water from these lakes to sustain their crops, especially during the dry season. 7. Raising Ducks and Other Livestock – The lakes could also be utilized for raising ducks, which can be a viable livelihood venture. A Question of Compliance and Incentives Despite the clear benefits, it appears that very few barangays are actively complying with this law. Could it be due to a lack of incentives or awareness? If so, barangays should realize that the long-term advantages—a stable potable water supply, enhanced local food production, and improved resilience against drought and floods—are incentives in themselves. Additionally, who should take the lead in ensuring that barangays implement this initiative? Should it be the Department of the Interior and Local Government (DILG), in coordination with agencies such as the Department of Environment and Natural Resources (DENR), the Department of Public Works and Highways (DPWH), and the Department of Agriculture (DA)? Since this should be an inter-agency effort, perhaps the DILG could oversee the initiative and ensure its implementation nationwide. Learning from Successful Man-Made Lakes Worldwide The United States has successfully utilized man-made lakes for multiple purposes. For instance: Lake Mead – Created by the Hoover Dam, it serves as a reservoir for hydroelectric power, irrigation, and flood control. Lake Powell – Supports hydroelectric power generation and tourism. Lake Texoma – Provides irrigation, flood control, and aquaculture opportunities. Lake Sakakawea – Used for hydroelectric power, irrigation, and food production. These examples demonstrate that, when properly planned and managed, man-made lakes can become valuable assets for communities. A Call to Action With climate change intensifying the challenges of water scarcity, food insecurity, and natural disasters, barangays must rethink their approach to water management. By transforming required water retention structures into multi-purpose lakes, local communities can harness the full potential of these resources. The question now is: Will barangays and government agencies take this opportunity to implement a truly sustainable and transformative solution? The benefits are clear. Now, it’s time to make it happen. Ramon Ike V. Seneres, www.facebook.com/ike.seneres iseneres@yahoo.com, 09088877282, senseneres.blogspot.com 03-19-2025
