Conserving surface water is a dire necessity

Conserving surface water is a dire necessity
Md. Asadullah Khan

Newspaper report indicates that in this high monsoon season, the water level at Kaptai Lake stands at 10 ft. below the usual level of water found in the preceding years. The report quoting Kaptai Hydroelectric Plant management sources further says that the level of water in the lake is now 77.70 ft. above mean sea level as against 87.36 ft. on the same date in the previous year. With the spillway closed, the lake in this rainy season, can retain 109ft of water (above mean sea level) paving the way for running five generator units that can produce 242 Mw of power in the lean period. The shortage has been caused because of inadequate rainfall in the Chittagong hill district region in this full monsoon season. Other than power production at a nominal cost of 70 paisa per unit that would be affected, this shortage of rain portends a crisis in respect of availability of water for crop production throughout the country.
