Crocodiles have been responsible for 51 deaths in the 52 months from January 1990 to April 1994. Of these, 18 deaths occurred in the first four months of 1994.

Local beliefs and superstitions about crocodiles include those about the taming of animals, with implications concerning the choice of victim and the penalties that may ensue if a crocodile is killed. The recent rise in human fatalities is thought to relate to increasing river pollution reducing the fish supply, together with a change in social mores at the riverside which has increased the crocodiles' displeasure. A reliable pumped water supply would reduce the need to draw water and bathe in the river, and eradication of superstition would empower the villagers in the fight against a common enemy.
