So far, ditto.
I see no evidence that any agency "knows", even internally, that bigfoot exists. In other words, no agency has an internal training or policy instructing their employees how to deal with a bigfoot report. In my area we have many millions of acres of national forest and BLM-managed lands. Employees of the two agencies in just this area number upwards of 500, maybe upwards of 1000, and none of them .. retirees included .. that I know, which is a **bunch**, have received any instruction regarding how react to a member of the public reporting bigfoot. The employees are left totally on their own. This also applies to people in the military stationed Fairchild AFB and JBLM over the years. As I've said before, SOME individuals working for various agencies surely have knowledge, but it is individual knowledge, not agency knowledge. There can be no conspiracy beyond a personal sense of need not to make waves that might interfere with promotions later.
While some folks may assert that lack of recognition is "proof" of a coverup, I don't think that is valid. It appears to fall in with the scoftics logic suggesting lack of proof is proof of lack .. and we know better than that. Since we know better, we shouldn't emulate it no matter how much we'd like it to be true.
