Hi Brian – the strava post was mine. I was up there on 9/28 around 4:30pm. According to the management plan, Stiletto is categorized as “Stocked with nonreproducing fish” so the plan is to “Discontinue stocking and monitor lake conditions”. I originally figured it was the NCNP applying chemicals but they said it was not them. Plus I think they are required to put up signs and the rangers are supposed to know to let campers know according to the management plan.
Bummer they won’t be able to get up there this year. It was a bizarre thing to see!
