I too was curious about the extent of the lake that was effected by the parasite. All accounts I had read referred to the lower end of the lake.
I fished Faubush Creek on Monday. I caught two stripers. One was 20" and one 27". Both fish had the parasite. The 20" had very few. The 27" had a whole bunch. I fear that if it hasn't made it to fishing Creek, it wont be long.
