LINCOLN -- A state task force is recommending $50 million a year for water-conservation efforts in Nebraska. The Water Funding Task Force says Nebraska needs a sustainable water supply for drinking, crop irrigation, interstate water compacts and wildlife. The task force says funding options could include a tax on soft drinks, an excise tax on ethanol, or taxes on fertilizer and bottled water. Task force chair, Holdrege Senator, Tom Carlson, says the state has overused its water supply and needs to find ways to preserve it. The report is due to the Legislature on Friday.
