SUMMARY OF IMPACTS...

THERE CONTINUE TO BE LOCAL...STATE AND NATIONAL NEWS STORIES ABOUT 
DRY WELLS IN THE SAN JOAQUIN VALLEY...EXCESSIVE GROUNDWATER 
DRAWDOWN AND THEFTS OF WATER FROM MUNICIPAL WATER SYSTEMS. THERE 
CONTINUES TO BE SIGNIFICANT MEDIA COVERAGE ON THE ON-GOING DROUGHT 
CONDITIONS. THESE REPORTS INCLUDE DISCUSSION OF SIGNIFICANT RE-
ALLOCATION OF WATER RESOURCES FROM THE EAST TO WEST SIDE OF THE SAN 
JOAQUIN VALLEY...FARMERS FORGOING PLANTING OF SOME CROPS... 
REDUCTION IN AIR QUALITY DUE TO PERSISTENT STAGNANT AIR...AND LOSS 
OR REDUCTION OF GROUND WATER.

THE OVERDRAFTING OF GROUNDWATER HAS CAUSED SUBSIDENCE IN PARTS OF
THE SAN JOAQUIN VALLEY...ESPECIALLY IN MADERA AND TULARE COUNTIES.
THIS SUBSIDENCE LIKELY HAS CAUSED SOME REDUCTION IN THE SPACING
BETWEEN SOIL PARTICLES DUE TO COMPACTION. THIS COULD IMPACT THE
AVAILABLE SPACE AVAILABLE FOR GROUNDWATER STORAGE...AND SOME
AQUIFERS MAY NOT RECHARGE TO PRE-DROUGHT CAPACITIES.
