Mono Lake used to be the biggest breeding ground for shorebirds. The
California aquaduct system diverted nearly all of the water that flows
into the lake for use in Los Angeles. The lake nearly dried up.
The lack of inflowing water not only lowered the level of the lake
but also increased the salinity. This reduced the population of
brine shrimp which lived in the brackish water and which the young
birds needed to feed off of before flying to new homes.
The islands in the middle of the lake became exposed all the way
to shore. This allowed land predators like foxes and coyotes to
simply walk across to the islands and feast on the birds' eggs.
The small community next to the lake fought for many, many years
and finally restrictions were created to keep the lake at a minimum
level. The birds are slowly returning to their nesting grounds.
