Fished it last yr with little success. Tried downriggers for koks but only 1 hit, went up the river arm for a few small browns that hit trolled brown pattern cast masters top lining.. have seen some large koks come out of there in the 15-18" range but was told by the person who showed me the pictures that he jigged for them and never used downriggers. A rather shallow res. about 70ft at the deepest from the dam and the east side of the res is the channel. The drive from Roseburg puts it in the same range for me to Odell,Crane prairie or Wickiup and its hard to pass diamond plus the mosquito are legendary known to carry off small children So its really about the wind if every body is blown out Lemolo is more sheltered
Also the lodge sells the mystic bug (I think that's what you call it) and that s suppose to be the only lure to use ??? and they just stocked it.
Post pictures when you go no matter the outcome.
