Narrative:
Ground operations normal. After takeoff gear door EICAS message illuminated; checklist accomplished and decision made to continue. Climbing through approximately 20000 ft left hydraulic quantity EICAS message illuminated. Fluid level decreased to .48. Checklist was accomplished; emergency was declared and flight returned to ZZZ. Checklist for complete left hydraulic system failure was reviewed. Descent and rtb was uneventful. Hydraulic quantity slowly decreased to .35. Pumps were turned back on for configuring; approach and landing. Hydraulic quantity decreased to .2 when the gear was lowered and remained at .2 for the remainder of the flight. Landing was uneventful; stopped straight ahead; pinned gear and aircraft was towed back to the maintenance ramp. Post-flight inspection confirmed hydraulic leak.

Title: B757-200 DEVELOPED HYD LEAK ON CLIMBOUT. FLT CREW DECLARED EMER AND FLT RETURNED TO DEP ARPT.
Narrative: GND OPS NORMAL. AFTER TKOF GEAR DOOR EICAS MESSAGE ILLUMINATED; CHKLIST ACCOMPLISHED AND DECISION MADE TO CONTINUE. CLBING THROUGH APPROX 20000 FT L HYD QUANTITY EICAS MESSAGE ILLUMINATED. FLUID LEVEL DECREASED TO .48. CHKLIST WAS ACCOMPLISHED; EMER WAS DECLARED AND FLT RETURNED TO ZZZ. CHKLIST FOR COMPLETE L HYD SYS FAILURE WAS REVIEWED. DSCNT AND RTB WAS UNEVENTFUL. HYD QUANTITY SLOWLY DECREASED TO .35. PUMPS WERE TURNED BACK ON FOR CONFIGURING; APCH AND LNDG. HYD QUANTITY DECREASED TO .2 WHEN THE GEAR WAS LOWERED AND REMAINED AT .2 FOR THE REMAINDER OF THE FLT. LNDG WAS UNEVENTFUL; STOPPED STRAIGHT AHEAD; PINNED GEAR AND ACFT WAS TOWED BACK TO THE MAINT RAMP. POST-FLT INSPECTION CONFIRMED HYD LEAK.
