On departure immediately after clean-up received EICAS message -- left hydraulic pressure and shortly after left hydraulic quantity. Pressure illuminated in left engine and left electric hydraulic pump switches. EICAS showed left hydraulic quantity was zero. Declared an emergency with departure and accomplished left hydraulic quantity and left hydraulic pressure checklist procedures. Had to extend gear and flaps using alternate system. Landed 1500 pounds overweight with 20 degrees of flaps. Landing uneventful. Shutdown on runway and towed into the gate. Maintenance said that the line coming out of the left hydraulic pump came loose and depleted all of the hydraulic fluid. There were no injuries and no equipment damage other than the loose hydraulic line.
