It would be my first option except I want to eat the fish and gunlock is full of heavy metals. As a rule I will not eat fish from enterprise, gunlock, or new castle. Lots of mines and metals in those drainges.
First, I respect such decisions. We still don't feed our daughter anything from most southern Utah reservoirs because she's so vulnerable to things like methylmercury. We also abstained for my wife while she was pregnant.
That said, Quail actually tests higher for methylmercury than Gunlock. And Sand Hollow is almost exactly the same as Gunlock. Many of our freshwater bodies actually get many of these toxins from the atmosphere and rain; makes it so complicated.
Luckily panfish don't bioaccumulate most toxins anywhere near the level species like bass do. As well, our bodies do slowly filter (sometimes multiple lifecycles of filtering) many of these toxins from our body as adults. My daughter will eat some growing up later in life but I'll probably limit until she's in her early 20s, when most brain development slows way down.
Best of luck mate. I hate that we have to consider such things given how healthy fish is for us. But it's also one of the reasons I now eat more sardines and mackerel compared to tuna, etc.
