Narrative:

During climb out from ZZZ; on the departure; climbing through 15000 ft; the right hydraulic pressure started to decrease and illuminated the right hydraulic light followed shortly after by the rudder control manual light. As the QRH was retrieved the quantity was noticed to be decreasing as well. The hydraulic pump was turned off and the quantity was 2 quarts. The QRH was complied with and contact was made with the company. An emergency was declared during the descent to ZZZ2 when the hydraulic quantity decreased so that at 15000 ft we were back to 2 quarts remaining and decreased to zero at altitudes below 15000 ft. Landing was accomplished in ZZZ2 with a manual gear lowering. Aircraft was landed on runway 14 anc. Manual gear lowering was normal. There was a delay getting the aircraft off the runway due to maintenance being initially unable to pin the gear doors up. After getting to the gate the maintenance crew said that the right gear well was dripping fluid.

Title: MD80 FLT CREW HAS A HYD MALFUNCTION; DECLARES EMER AND DIVERTS FOR LNDG.

Narrative: DURING CLBOUT FROM ZZZ; ON THE DEP; CLBING THROUGH 15000 FT; THE R HYD PRESSURE STARTED TO DECREASE AND ILLUMINATED THE R HYD LIGHT FOLLOWED SHORTLY AFTER BY THE RUDDER CTL MANUAL LIGHT. AS THE QRH WAS RETRIEVED THE QUANTITY WAS NOTICED TO BE DECREASING AS WELL. THE HYD PUMP WAS TURNED OFF AND THE QUANTITY WAS 2 QUARTS. THE QRH WAS COMPLIED WITH AND CONTACT WAS MADE WITH THE COMPANY. AN EMER WAS DECLARED DURING THE DSCNT TO ZZZ2 WHEN THE HYD QUANTITY DECREASED SO THAT AT 15000 FT WE WERE BACK TO 2 QUARTS REMAINING AND DECREASED TO ZERO AT ALTS BELOW 15000 FT. LNDG WAS ACCOMPLISHED IN ZZZ2 WITH A MANUAL GEAR LOWERING. ACFT WAS LANDED ON RWY 14 ANC. MANUAL GEAR LOWERING WAS NORMAL. THERE WAS A DELAY GETTING THE ACFT OFF THE RWY DUE TO MAINT BEING INITIALLY UNABLE TO PIN THE GEAR DOORS UP. AFTER GETTING TO THE GATE THE MAINT CREW SAID THAT THE R GEAR WELL WAS DRIPPING FLUID.
