Major efforts to conserve water
are most evident in areas where
water supplies now limit crop
production, or where available supplies
can be expected to decrease
severely in the near future. Use
of water-conserving practices in
these areas may be stimulated by
legal actions that prohibit irrigation
tailwater from entering barrow
pits along roadways, because of
expensive silt removal, or from
entering shallow lakes where water
may be wasted through evaporation
