Abstract: After two years'field and laboratory observation, the results of this study have practically answered the question of the possibility of northward migration of Oncomelania snails due to China's South-to-North water diversion project. This paper has provided the main scientific reasons why the areas north of 33°15'N in China are not suitable for the living and multiplication of the Oncomelania snails. Also effective measures are suggested to prevent the migration of the snails. Findings of the study may be important for the planning and assessment of the South-to-North water diversion project.
