The Poribesh Bachao Andolon (POBA) made six recommendations to protect Dhaka's remaining lakes, including handing over lake management to city corporations and recovering illegally grabbed land. The lakes still surviving in Dhaka are Gulshan-Baridhara, Gulsahn-Banani, Dhanmondi, Ramna, Cresent, Hatirjheel and Uttara. POBA also recommended stopping the dumping of household and medical waste in lakes and better treatment of bio-waste. They warned that if preservation laws are not properly enforced, Dhaka's lakes will be illegally grabbed and polluted and lost by 2030.
