That is what i was afraid of. If i didn't already spend so much on minnows i would be tempted to drain the whole thing and start again.... but then again the same thing could happen. The feeder creek is extremely shallow and fast moving, so the BG and LMB in it seem unlikely. It is made from mountain springs, so it is also very cold. It is 20 foot wide but you can walk across in most spots and not get your ankles wet. I have seen small minnows in the deeper holes but never any sizeable fish. We do get geese and cranes in the pond, i wonder if they could transplant some. Here is a photo of the blue gill, i don't think it is a GSF. Also, a mystery minnow i spotted a few weeks ago and have not seen since. It was almost translucent with a pinkish stripe. Wondering if it is a rainbow. I will try to catch one of the LMB on a lure since it won't take a worm or nightcrawler. I have a minnow trap, i will get that in the water and see what i can get.
