I do believe they have moved on. I see zero sign of any anything. This fall i plan to drop the water and kill whats left. I need to do a little maintenance while it's down. I have bought two traps. The TWRA has explained the best way of using them. He has given me a couple of options. I have found an older gentleman that has the same exact problem. He is a wealth of information and agreed to help me.

I have already picked out my new toy. The traps are a little more healthy than I expected.

Savage 110 Predator in 22-250 24 inch threaded barrel
AGM 50-384 V2 Varmint with ballistics calculator
Can on the end...
Using, Hornady superformance 22-250 varmint 50 grain

Yes, I've done my homework.
No, this will not pass.
Yes, I'm mad.
Yes, they are gonna die...
Im stubborn. I don't care if it takes 5 years.
