Narrative:

Soon after reaching cruise altitude of 37;000 ft; we received an ECAM: hydraulic B system lo pr. We complied with the ECAM and turned off the blue electric hydraulic pump. At this point; we ran the checklist per SOP for a non-normal laning and completed the landing distance procedure. We called dispatch and maintenance for a conference. While talking with maintenance; we received a hydraulic B rsvr lo lvl. The only difference from the previous ECAM was not to turn the blue electric pump on during approach. Otherwise; all protocol remained the same. Maintenance entered the failure into the maintenance history and informed arrival station maintenance. We discussed the issue with the flight attendants. We declared an emergency with ATC and asked for 34L and direct our destination VOR. Once we checked on with ATC; they assured us that airport authorities had been notified and emergency equipment was ready. We continued and landed on 16R without further incident.
