Lets check out the chart:
Chart 12273
Well, the restriction on chart 12273 says:
"ABERDEEN PROVING GROUNDS RESTRICTED AREA 334.140 (see notes A and C)"
remember that number,
334.140
Note C:
"CAUTION- Unexploded ammunition or ordnance (duds) may exist within the limits of the restricted area"
Note A:
Navigation regulations are published in Chapter 2, US Coast Pilot 3. Additional revisions to chapter 2 are published in the Notice to Mariners..... etc etc etc.
So we go to the US Coast Pilot 3, Chapter 2:

Go to page 143-144 for the full official explanation. But the main points are:
§334.140 Chesapeake Bay; United States Army
Proving Ground Reservation, Aberdeen,MD. (that number looks familiar!)
(b) Authority delegated Commanding Officer. The
Commanding Officer, Aberdeen Proving Ground, has
been delegated the authority by the Secretary of the
Army to designate from time to time by suitably posted
bulletins or announcements, the conditions under
which the public, including food fishermen and
crabbers, may enter restricted waters of the Aberdeen
Proving Ground.
(2578) (1) The following water areas are closed to the public
at all times:
see list of fully restricted areas too long to copy and paste
(2585) (2) The remainder of the restricted areas will normally
be open for authorized use (including navigation
and fishing) during the following hours:
(2586) (i) Monday through Thursday, 5 p.m. to 7:30 a.m.;
(2587) (ii) Weekends, 5 p.m. Friday to 7:30 a.m. Monday;
(2588) (iii) National (not State) holidays, 5 p.m. the day
preceding the holiday to 7:30 a.m. the day following the
holiday.
(5) Authorized use. Authorized use as used in this
section is defined as fishing from a vessel, navigation
using a vessel to transverse a water area, or anchoring a
vessel in a water area.
Any person who touches any
land, or docks or grounds a vessel, within the boundaries
of Aberdeen Proving Ground, Maryland, is not using
the area for an authorized use and is in violation of
this regulation.
(2590) (4) A fleet of patrol boats will be positioned at the
perimeter of the restricted water zone boundaries (except
in extreme weather conditions such as gales or
ice) during periods of testing to prevent unauthorized
entry. If necessary to attract attention of another vessel
about to penetrate the restricted area, the patrol boat
may operate a distinctive rotating blue and red light,
public address system, and sound a siren, or by
radio
contact on shipshore FM channel 16 and citizen band
channel 12. Buoys will mark the restricted waters
along the Chesapeake Bay perimeter during the period,
normally 4 June through 1 October annually.
long story short, you may go through during allowed times. if you try to go through when they don't want you to a patrol boat will let you know. and don't try to set foot on dry or subaqueos land (that means no getting grounded). sorry, no self guided tours of Pooles Island Lighthouse.
