This was early this summer.  MY FIRST PIKE!!!  As I am sure you can tell we were very excited.  We have been seeing them in the river for a while and we had not been able to get one hooked up. Pike are an invasive species on the Green, that have came up from the Yampa.  If you catch burbot, northern pike, smallmouth bass or walleye, on the Upper Colorado River system you must immediately kill them.
