Joe and I fished an overgrown pasture at the out most head water of a stream we frequent. It was obvious that no one had fished the area for quite some time. We were picking up trout in water that had any type of depth. The median depth in the flats was about 2 feet. Everywhere there was a corner or tree on the water there was a slight bit more depth and the trout were stacked up in there. None of the trout were huge. Most of them were very skinny. We kept going upstream and catching a trout about every fifth cast. I landed a skinny male brown with a wound on its head. A heron had been fishing this stretch also. The water really started to get skinny and the weeds were hanging over the stream making casting almost impossible. Joe and I decided we would walk a little farther upstream. We walked through a really skinny area and were about to quit when Joe heard some rushing water. We decided to go find the source of the noise. We walked 20 more yards and we found a man made structure. It looked like a flood control mound. It had a pond below it. There was a cement tube coming out of the earthen mound. The pond had willows all around it and it is tight casting. The pond appeared to be about 3-4 feet deep and about half the size of a small swimming pool. I threw a panther martin in there with no luck. Joe hooked on his sure fire rig. A size 6 eagle claw with a large night crawler hooked through it once. Joe threw up to where the cement tube dropped water directly in to the pond. The crawler didn't even get a chance to sink and Joe had a trout on. The trout was about 16 inches. Joe turned his head towards me as he battled the trout. Joe was gloating. He was dissing me for my pick of trout bait. He told me that there was nothing like a night crawler for trout. I was watching the trout as Joe battled it. Joe was still looking at me chirping. He was singing his own praise and how he was going to out fish me again today. The water near the trout erupted and I saw the 16ish inch brown go sideways in the water. This got Joe's attention and started paying attention to the trout on the end of his line again. Joe reeled a little faster and had the trout about 15 feet in front of us. The water erupted again and this time the action was directly in front of us. We both stared in disbelief at we just had seen. Joe let the trout rest for a moment. He asked me what I had seen. I told him I saw a massive female brown run in to the side of the trout on his line and push it sideways. Joe had me get my camera out in case the GIANT female brown did it again. I wanted to get a photo of the trout attacking Joe's trout. Nothing happened. We landed the trout and let it go. Joe was shaken. he asked me how big the attacker was. I told him a least double the size of the trout on his line and very deep. We measured the trout that Joe had landed. It measured 16 1/4 inches. The trout that attacked it was clearly over 32 inches and the deepest trout I have ever seen in a small stream. It was a female brown. We both got a really good look at it. We tried for that trout for 2 hours after that and not a whisper. On the way home we made our plan of attack. We decided a return trip the next morning was in order. I rigged up three poles and so did Joe. Joe took his 6 pound mono off his normal rig and put 20 pound power pro on his rod. Joe put 0x on his fly rod and put a deer hair mouse on the fly rod. His other rod he put a black Mr. Twister on. I sized up on my fenwick. I put 10 pound fireline on it. I decided this trout was landlocked and could not escape down stream. I went to cabelas and bought a size 7 and 9 floating rapala in the brown trout pattern. My second spinning rod i put 8 pound clear mono on it and bought a mouse lure. The lure had 2 treble hooks and a slight bill on it. Lastly I put a size 2 black bunny leech on my 6/7 fiberglass fly rod. We were at the hole by 4:45am. We exited with our tails between our legs. Not a whisper of a bite. We talked on the way home. Joe thought the next time we went he was going to try live chubs and chub tails. The hole was big enough that we couldn't cover the entire hole with a fly rod. Good back casts are almost impossible. We discovered this trout about 3 weeks ago. We have gone back approximately 15 times at different times of the day and night. We have not caught another trout in that hole since then. That trout is land locked it can NOT get out unless it jumps a spillway and negotiates 6 inch deep water for 60 yards to a tiny stream that runs through a long pasture. It is still in there. This trout is quite a head scratcher. We have thrown the kitchen sink at it. It ignores everything we have tried. Joe was thinking about a live mouse on a harness. Couple of my friends have suggested a huge hopper when they come around or a big cricket. I am open to suggestions. This trout is quite a puzzle. I am 100 percent sure it is still in the hole. It is like having a jigsaw puzzle almost finished and losing the final couple pieces. This trout is soooo huge it is a no brainer on what we are going to do with it if we ever crack the code.
