After extending the landing gear on final approach we got an EICAS message for low quantity in the left hydraulic system. When we selected the status page to view the quantity we saw almost nothing remaining. Additional EICAS messages appeared for low pressure in the left system. We accomplished a go around and discussed our options. I worked with the QRH and ATC while the Captain flew the airplane and talked to the flight attendants and passengers. The gear and the flaps stayed at 25 the entire time. I declared an emergency and told ATC that we would like to divert to another airport. I also told our Dispatcher about our situation. After completing the QRH we set up for a visual to the runway. The approach and landing were normal. The Captain was barely able to turn off the runway and we stopped and shutdown the engines just clear. Emergency equipment was standing. They told us that fluid was leaking from the nose wheel area. Operations sent out a mechanic and a tug. The aircraft gear was pinned and we were towed to the gate.
A B757-200 flight crew declared an emergency and diverted to an airport with a longer runway after the left hydraulic system failed when the landing gear was extended.
