My guess is big south will definitely be running good in a week, probably nice medium levels. Natural flow is tapering off quickly and flows out of long draw are coming down too. Should be a pretty good season for big south as well. My guess would be most of July. Long draw res is full and spilling over right now, so they have a lot of water to release for irrigation downstream. They are also bringing over a good bit of water in the grand ditch into long draw since its been a pretty good water year, especially with all the june rain.
If big south is going good, spencer heights should still be good, but joe wright is a different story. Not sure how the plumbing works on joe wright since it has a res at the top too.
I was at big south in early june, and the skeeters hadn't come out yet. So nice. Made the mistake of not putting on the bug spray and got annihilated a week ago. I'll be ready for skeeter battle this weekend.
One boater had a full mosquito suit last year. Kinda goofy looking, but certainly functional, and nicer than itching for a week afterward.
