At FL310 we had a caution 'HYD 1 LO PRESS' message. Followed QRH and the B pump did not function either. The steps led to 'Land at the nearest suitable airport' so I contacted Dispatch and discussed where to go. It was decided that we would divert to ZZZ. Because the number 1 EDP was not working and its' backup was also not working; and the fact that we were diverting; I declared an emergency. Weather was not a factor. The First Officer was the flying pilot but I decided that I would perform the landing and did so. EDP 1 failed as well as its backup. Had the B pump worked diversion would not have been necessary. Time is always a factor rushing can lead to errors. The change in mind-set can be a distraction (changing destination getting weather and other data). No undesired states occurred and the First Officer and Flight Attendant both did a very good job dealing with the situation.
En route at cruise (31;000 FT) we received the caution message 'HYD 1 LO Press'. I continued to fly while Captain ran the appropriate QRH procedure. The procedure had us turn on the 1B hydraulic pump. This proved to be ineffective; so continuing with the procedure; it required us to proceed to the nearest airport to land. Captain contacted Dispatch and together they decided; the best option (airport) for us to divert to. Captain then communicated with ATC (declared emergency); the Flight Attendant; and passengers and informed them of the situation. ATC gave us instructions and had us proceed directly to our divert airport. Since Captain declared the emergency; he assumed controls and landed the aircraft safely.
CRJ200 flight crew experiences a hydraulic system 1 failure at FL310. The 1B pump will not pressurize the system either and the crew diverts to the nearest suitable airport for landing.
