The upper Blue basin is extremely shallow and stumpy. All the lake has stumps and submerged wood, but that part of the lake is challenging at best but I have caught loads of fish there on occassions when the wind is almost calm. Since I fish out of an Alweld with jet, shallow is no issue but the stumps still catch me at times. I see the weather is set to make a real winter turn for a couple weeks, so if the water temps drop it will slow whatever bite there has been to date. Good luck no matter!
