A CRJ-900 First Officer reported receiving HYDRAULIC 2 HI TEMP caution message after takeoff. They ran the procedure; coordinated with Dispatch and Operations; and elected to continue to destination.

Narrative

Departing; climbing through 10;000 FT we received a HYDRAULIC 2 HI TEMP caution message. We ran the checklist which led us to close the right hydraulic shut off valve. We contacted Maintenance and Dispatch and we all concluded that we should continue onto our destination and have a mechanic waiting for us at the gate. We discussed the possibility of having to do a flaps 20 landing; but between Dispatch and our checklists we concluded that since we would be turning the HYDRAULIC 2 pump to Auto prior to landing we should be able to make a normal landing. On our descent check we ran through the checklist one more time; selected the Hydraulic 2 Pump to AUTO. We set up for a normal approach to landing at our destination. I called for gear down; flaps 30; speed 170. The flaps remained in the 20 degree position. We contacted Tower and asked for a go around. Tower told us to follow the localizer and then gave us a downwind turn and a climb to 3;000 FT. We informed both Tower and Departure that we had an issue with our flaps; would be running a checklist and would return to land shortly. We completed the flaps 20 briefing; and ran through the remainder of the checklist for a flaps 20 landing. Approach asked us if we were declaring an emergency and we said negative; we will just be using more runway. The airport had emergency vehicles standing by; we flew a flaps 20 approach to land; proceeded to make a right turn at the end of the runway and taxied to the gate without further incident.
