California lawmakers late Friday approved a massive increase in fines for water scofflaws after ranchers intentionally defied state orders and pumped water from the drought-plagued Shasta River for eight days.

Two years ago, state officials imposed the maximum fine allowed under law — $4,000, or roughly $50 per rancher, causing outrage among tribes and conservationists. The river provides vital habitat for salmon, and California was experiencing its driest three-year stretch on record.
