State Rep. Allan Ritter, R-Nederland, filed two bills Thursday that would allocate a one-time, $2 billion sum from Texas' Rainy Day Fund to create a revolving fund for water-supply projects. Ritter, who chairs the House Natural Resources Committee, is a key figure on water issues in the drought-ravaged state. House Speaker Joe Straus, R-San Antonio, has said he is looking to Ritter's leadership on water. Of the several water bills and proposals from state leaders, Ritter's proposed sum is the largest; he wants to get initial money from the state's Rainy Day Fund.
