Shortly after gear up we received an EICAS message L HYD SYS PRESS in addition the status page Indicated RF for the Left Hydraulic System. We determined we had lost all the Left Hydraulic System fluid; I advised ATC of the problem; I declared an emergency and informed ATC we intended to return. I requested the First Officer run the QRH. We secured the Left Hydraulic System as per the checklist. We also advised Dispatch informed the flight attendants and made an announcement to the passengers. I requested one holding turn to run the after takeoff; arrival checklist and review the landing adjustments due to the loss of the Left Hydraulic System. We made a normal ILS approach and landing. We had requested the emergency equipment stand by. I turned the APU on and after we exited the runway ATC requested we stop and wait for the emergency personal to inspect the aircraft. I shut the engines off and kept the brakes off. I was than informed the left landing gear had some smoke that was subsiding coming from around the brakes. The Emergency Personal cleared the aircraft to be towed to the gate.
Turning to 270 heading climbing through about 2;000 FT; noticed caution lights on the EICAS. [We] noticed L HYD SYS PRESS light. Rudder ratio and hydraulic quantity [were] also on. We ran the L HYD SYS PRESS QRH checklist and returned to a landing. Declared an emergency; called CFR and advised Dispatch on ACARS that we were returning. The Captain preformed the landing.
