...and perhaps a little insight.
I work for the Corps of Engineers. I work in the Little Rock District. However I LIVE in the Vicksburg District. In MY district I can detect any "predisturbed area" I wish and will have no problems with anyone.
However, in the Vicksburg District, who also is under Title 36 (like the rest of USACE) THEY make me fill out a "Special Use Permit CLMK Form 2286, dated Nov 92, for EACH and EVERY separate lake I detect. There are FIVE in my driving area. My brother detects with me and therefore we have to get TEN separate permits--just because Vicksburg is so uptight about the issue.
Recently, I spent 30 days in the Savannah District, but they have no restrictions. The Corps is consistently inconsistent.
Now, for those of you who are encountering gate attendants who are not receptive to you:
They are NOT Government employees. They are either volunteers or are paid varying salaries because they are CONTRACTUAL employees.
If you have one of these folks giving you grief, just ask them to call the duty ranger. That will settle it once and for all. They should become most docile.
Metal Detecting on Corps property is allowed, as long as it is in a pre-disturbed area. such as playgrounds and designated beaches.
My Special Use Permit (that I fill out) states I can detect ALL designated beaches and playgrounds. Recently I had a gate attendant that said, 'well, THIS beach is for campers ONLY.' I simply showed him my paperwork and asked him to call the duty ranger if he had an issue of my presence on the "camper only" beach.
If, for some reason, you wish to detect, say old foundations or anywhere else, you will need a Special Use Permit in order to do that. Each District has their own. However, you wil need to go to the specific PROJECT OFFICE of the lake you want to hunt to get your permit. Going to the District is a waste of time, believe me.
It's good to carry the blurbs i saw listed. Can't ever tell when you will have a "schoolboy" ranger (summer ranger) that has a badge, a clipboard and a new pick-up, that calls himself a "Ranger." In THAT case, you should show him the goods. IF he does not comply out of ignorance or arrogance, you should seek an appointment with the Supervisory Ranger at THAT particular Project Office.
Hope this helps you. Don't feel intimidated about detecting Corps land. Knowledge is power.
Now, Forest Service and National Parks land.....that's an entirely different issue.
Have a GREAT day. The days are getting shorter, so get with it while you can.
