While Bool Lagoon is officially a
game reserve, in dry years it attracts many waterbirds of many species, and is frequently a point of contention between
duck hunters and animal rights activists. The adjacent
Hacks Lagoon Conservation Park also provides refuge for waterbirds. There are a number of boardwalks and bird hides at both lagoons to facilitate
birdwatching. The lagoons are visited by up to 150 species of birds, many having migrated from the
Northern Hemisphere. The reserve is classified as an
IUCN Category VI protected area. Another ecological issue is that in the past, hunters used much lead shot. In recent times, even when the lagoon is opened for hunting, only steel shot may be used. ==Hydrology==
