Document Summary
Coastal prairies dominated by switchgrass(15ft long roots for water absorption) Asphalt doesn"t allow water to go into soil. Terminal lake=no outlet=salts accumulate in the lake water. 1941-50g/l salt (compared to oceans of 31. 5 g/l) and 1982 (after la used for water) 99 g/l. Mono lake=no fish, brine shrimp, algae, birds (about 2 million a year during migration) 1982= so much water was diverted that lake was reduced to 69% of its 1941 level. 1990=dropped 45 feet and lost 50% of its 1941 volume. Food chain will be affected by the saline levels ie the food chain. Algae won"t grow, shrimp die off, birds stop visiting. 1978=citizens formed to protect mono lake ecosystem and it grew to 20000 members. 1994= won battle of trying to reduce the water taken from the lake. Goal is 6392 ft and currently is 6381. 4 ft as of 8/9/17. Mono lake story=activities of humans, lives of other organisms or processes in the environment are all interconnected.
