Gough's silver medal is key because it comes with less than two weeks from the start of the 2014 Olympic Winter Games in Sochi.
Gough posted a time of 1:24.052 to place in the second position. Kate Hansen of the United States won the gold medal with a time of 1:23.976 with Russian Natalia Khoreva winning bronze with a time of 1:24.155.
Gough was actually in the lead after the first run, but only had the fourth fastest time in round two.
The Latvian World Cup did not see many of the top Germans participate as they are probably resting for the 2014 Olympic Winter Games in Sochi--a competition where they will be considered the heavy favourite to dominate.
Chrstian Obsterolz and Patrick Gruber of Italy won the men's doubles luge.
