Special Notices

This is the season of fireworks displays, sailing events, regattas, races, rowing, tall ships visiting, swimming around islands and across bays and many other types of summer events. There are far too many to list here. Bridges may be closed, channels inaccessible and waterways blocked, usually only for a few hours. Events for each USCG District are listed either within the body of the Local Notice to Mariners or as an enclosure at the end. Check http://www.navcen.uscg.gov/?pageName=lnmMain.*

*Italicized text above and below indicates our comment or paraphrase.  Plain text is copied from the Notices to Mariners or other sources given.

Lake Okeechobee Low Water Warning:
U.S. ARMY CORPS Of ENGINEERS CAUTIONS MARINERS, PUBLIC ABOUT DANGEROUS LOW WATER LEVEL CONDITIONS
1. The U.S. Army Corps of Engineers, Jacksonville District cautions mariners, property owners and the public to be mindful of low water level conditions when planning and conducting activities in, on or near lakes and waterways across the entire lower portion of the Florida peninsula.
2. Most of the south Florida region has experienced extremely low precipitation in the last few weeks. This lack of rainfall in the early days of the wet season has contributed to a prolonged, record-setting dry period, resulting in dangerously low water levels.
3. During such low water conditions, bad weather can have an immediate impact on vessels. Heavy winds can cause boats to run aground as resulting wave action causes depth of the water to be substantially reduced.
4. The Notice to Navigation is a guide for daily locking times at St. Lucie Lock and W.P. Franklin Locks in relation to lake levels. Based on that guide, at lake levels of 10.5 to nine feet, there will be two lockages per day at 9 a.m. and at 4 p.m. at St. Lucie and W.P. Franklin Locks. At a lake level below nine feet, there will be only one daily lockage at noon. Though the Corps will not close the waterway to navigation, it will simply become the de facto status should water levels get too low.
5. Lake Okeechobee today stands at 9.73 feet NGVD and continues to drop. A lake elevation of 9.73 feet results In a channel depth of approximately 3.63 feet on Route 1 of the Okeechobee Waterway, which crosses the lake. The Route 2, or Rim Canal, channel depth is currently approximately 1.83 feet.
6. Mariners are advised that if they decide to cross lake Okeechobee they are doing so at their own risk, and are warned not to leave the Route 1 channel, to avoid uncharted waters and be aware that depths could change without notice.

GPS Enhancement Announced:
            The US Air Force issued a media release stating that enhancement of the Global Positioning System (GPS) constellation has been completed. The enhancement project, known as “Expandable 24”, consisted of two phases. In the first phase, three of the 24 GPS satellites were maneuvered to more optimal orbits. In the second phase, another three satellites were also maneuvered to new orbits. The project has increased the robustness of satellite availability and overall signal in space performance, resulting in a higher probability of signal acquisition. (6/15/11).

Long Island, NY, Shellfish Ban for Potential Sewage Discharge in NDZs (No Discharge Zones) AGAIN this Summer:
            The New York State Department of Environmental Conservation will temporarily designate a section of West Harbor (within Oyster Bay Harbor); all of the Sand Hole within Caumsett State Park, on Lloyd Neck; and a section of Port Jefferson Harbor including the area known as the Narrows, as UNCERTIFIED for the harvest of shellfish from sunrise on Saturday, July 2 through Thursday, July 7, 2011, both dates inclusive. The harvest of shellfish is prohibited during the period these areas are designated as uncertified. This designation is necessary to protect public health and is required due to the potential for sewage discharges from marine sanitation devices on the large number of transient vessels which will anchor and remain overnight in these areas over the holiday period. A recorded message describing any temporary shellfish closures that may be in effect in New York is accessible 24 hours a day by calling (631) 444-0480. The DEC’s website provides detailed information including map images of the closed areas: http://www.dec.ny.gov/outdoor/35917.html
            Following is a description of the areas that are affected by this temporary closure: (1) All the waters of West Harbor, within Oyster Bay Harbor, lying west of Centre Island and east of a line extending northerly from the northwesternmost point of land approximately 600 yards north of Brickyard Point (on Centre Island) to the westernmost point of the beach pavilion at Centre Island Beach. (2) The Sand Hole, within Caumsett State Park, located near Lloyd Point. (3) All the normally certified area of the Port Jefferson Harbor Complex, including the Narrows, which links Port Jefferson Harbor to Conscience Bay.
            Town owned pump-out facilities will be available in or near the restricted areas at no cost to boaters; town pump out boats can be hailed on marine radio VHF channel 9 in the Towns of Oyster Bay and Huntington and on marine radio VHF channel 73 in Port Jefferson Harbor. (First District LNM 25). NOTE: This ban has occurred every summer during times of large gatherings of boats for holiday celebrations in NDZs (No Discharge Zones) in New York waters since we have been archiving the digital editions of Coast Guard Local Notices to Mariners, starting in 2008.

Finally--Steel Bridge (Dominion Boulevard) Replacement Proposed:
            The U.S. Coast Guard has received an application from the City of Chesapeake VA for the proposed replacement of the existing Dominion Boulevard Bridge, at AIWW mile 8.8, across the Southern Branch Elizabeth River, along US 17, at Chesapeake, VA. The City proposes, under the Dominion Boulevard Improvements Project, to convert the existing Dominion Boulevard/US 17 to a limited access 4-lane toll facility from Interstate 464/64 interchange to a point approximately 0.75 mile south of Cedar Road. The proposed improvements include widening of Dominion Boulevard to a 4-lane divided toll roadway and the replacement of the existing Dominion Boulevard/US 17 Bridge, 2-lane double-leaf bascule (commonly known as the Steel Bridge) and its approaches, with a new 4-lane high-level fixed bridge and new approaches on essentially the same alignment. In addition, the City is seeking authorization to remove the existing foundations to 2 feet below the existing mud line versus removal its entirety. Full removal of the existing foundations will greatly disturb and loosen the soils surrounding the new pier foundations, severely reducing the lateral capacity that is critical for a 95-foot high-level fixed bridge. A new fender system will be constructed. The proposed vertical clearance for the new high-level fixed bridge is 95.0 feet, above mean high water. The proposed horizontal clearance between the faces of the fender system is 125 feet. Comments on the proposed construction of the new bridge should be forwarded to the above address attention (dpb) NO LATER THAN July 13, 2011. Copies of Public Notice 5-1228, which describe the proposal in detail, can be obtained by writing to the above address, by calling (757) 398-6222 or by viewing at http://www.navcen.uscg.gov/?pageName=pnBridges.
