Narrative:

We got a warning message on our EICAS hydraulic system 3 lo press. Per our checklist we were to switch pumps to rectify the situation. The checklist directed us to land at nearest suitable airport if the pressure dropped below 1800 psi (which it was still about 2700 psi) since this was an alerted message I informed our maintenance through ACARS and also notified our flight attendants that if this got any worse we would have to divert. The pressure in hydraulic system 3 continued to decrease even with the 2nd pump running; and the system pressure fell below 1800 psi. Advised ATC; got a vector for ZZZ (we were closer to ZZZ than other places and knew they had the runway length; crash fire rescue equipment; operations and other facilities to assist us). Descended without incident. Fas notified of the divert; passengers notified of our situation. We ran all applicable checklists and prior to landing we had to manually deploy our landing gear (as that system directly controls the landing gear) gear came down without issue; we got cleared for the visual and landed with crash fire rescue equipment awaiting. Were able to clear the runway slowly but had to get chocked when clear as we had no parking brake; or tiller steering (rudder pedals worked adequately for us to clear [the runway]) fas notified when we were clear to keep passengers seated and that we would be towed in by operations; and I made a PA to the passengers explaining what would happen next. We were towed; crash fire rescue equipment finished inspecting the plane; and at the gate we deplaned the passengers normally.

Title: CRJ-700 First Officer experienced a loss of pressure in the Number 3 hydraulic system and the flight diverted to the nearest suitable airport. The landing gear was extended manually and the aircraft was towed to the gate.
