Great story! I especially like the pics of the hungry heron. I've seen lots of other birds try to steal hooked fish, from gulls to loons. Never a heron tho . . .
One of these days the heron will go missing... spey pattern fly tiers will be held suspect.
He/she perches on a structure close to the dam. Once the critter notices an angler has hooked a fish, it decides to help land the trout. I've yet to see it actually grab a fish from an angler but it sure comes close. I don't think Rock had any idea how close the bird was flying over him.
