The average recorded discharge at Dolores is 291,000 ( acre-feet acrefeet ) annually , which when adjusted for normal years by comparison with ( Ani- Ani ) mas River at Durango would be increased to 319,000 ( acre-feet acrefeet ) . Inflow from Beaver Creek and other drainage to the dam site would add 20,000 ( acre- acre ) feet . On the basis of an average year , the relation of water supply and demand for an ( 80,000-acre 80000acre ) ( de- de ) velopment would be as follows : , .
