Emigrant Lake and Applegate Lake are very similar in this topic. Both lakes hold largemouth, but the most caught are red eyes. I lived in the Applegate Valley from when I was six to now (I'm almost 22) I've fished both Applegate and Emigrant looking for largemouth. Emigrant Lake is a lot easier to catch a largemouth than Applegate. I've only caught one largemouth out of that lake and it was during the winter. The lake was super cold, low, and very hard to find solid ground near the water. My suggestion would be to fish deeper, try carolina rigging with a slow retrieve. See if that works out!
