Version G2 of Winnipesaukee/Garmin to be released in April, 2008
Go to http://bizer.com/garmin for the latest progress on Bizer's Garmin project. (updated 02-APR-08) *** We now have Garmin DataCards, SD cards, or MicroSD cards pre-loaded with our Winnipesaukee version G1 or G2.
Bizer has increased its $100 REWARD up to $250

Bizer's goal is to find and chart EVERY shallow area of Lake Winnipesaukee. If you can find a place that's less than six feet deep that Bizer has failed to mark in blue, Bizer will give you a reward of $150.00 to $250.00.
No correction to Bizer's map is too small. email us at winni@bizer.com. We really do want to make this a perfect product. With your help, we might just do it.
Lake Winnipesaukee's surface level is measured in feet. Readings are made daily by the New Hampshire Department of Water Resources. The datum (zero point) is 500 feet above sea level. Median heights are based upon data from 1984 through 2002. As a rule of thumb, assume: High Tide: June; Low Tide: February. Temperature, (F), readings are taken at the Lakeport Dam about one foot below the surface.
The below historical statistics are updated periodically, normally weekly.

Notes:
![]()
Apr-06 - A new red-top buoy has been added about 200m (650 ft) north of lighted buoy #57 near Norway Point. It marks a rock about six feet below the surface that could be struck by deep-draft boats when the water is low.
Apr-06 - A new NO-WAKE zone has been established between Governors' Island and Eagle Island at lighted buoy #2.
Apr-06 - A new restaurant, the Downtown Market Grille, has opened on Railroad Avenue in Wolfeboro. They serve breakfast and lunch.
Mar-06 - A Locke's Island resident has informed Bizer that The Lyons Den restaurant has opened at the former location of Townsend's Tavern (which was formerly Gilford Tavern which was formerly Gretchen's Restaurant).
Oct-05 - A new red-and-white buoy has been set off Umbrella Point, Wolfeboro Neck. Bizer (and only Bizer) already shows a rock at this location.
Oct-05 - The westernmost of two red-and-white buoys at the southeast end of Winter harbor has been moved. It has returned to its pre-2002 location next to a rock.
Oct-05 - The NO-WAKE buoy at the entrance to Minge cove has been moved east.
Oct-05 - There is a new black-and-white buoy in the northwest part of Langdon Cove (southern Moultonboro Bay). This now marks rocks that are at least 100m from the shore. Note that these rocks have always been on Bizer's chart and only on Bizer's chart.
Oct-05 - A red-and-white buoy at the southern end of Pine Island has moved more than 100m SW. Bizer thinks this is an error or was moved by ice. The Marine Patrol intends to return it to its 2004 location.
Oct-05 - A new black-and-white buoy was found on the eastern side of Stonedam Island at N43°-37.920' - W071°-25.940'. On Bizer's chart, it is almost 3 mm north of the "53" foot depth. The black-and-white buoy 5 mm SSE of the "53" foot depth was not found during Bizer's survey of the lake in 2005.
Oct-05 - On Bizer's 6th edition, three red-and-white buoys are depicted southwest of Fish Island. The easternmost of these is missing and was also missing in September 2004. Be advised that there is a rock at this location.
May-05 - At the southern end of Green's Basin, there are two rocks. Rock "A" is clearly visible as it sticks about 3 feet above the water. Rock "B" is below the surface about 50m (160 ft) north of rock "A". If you look closely at Bizer's chart, the red-and-white buoy marks rock "B". This is where the buoy was until 2002. In 2003 the Marine Patrol assured Bizer that the buoy would be returned to the proper location just west of rock "B". As of October, 2004, the buoy was still west of rock "A". A boater hit rock "B" and then decided to take a photograph (click here) of someone standing on the rock.
Feb-05 - Black Cove on Meredith Neck has been designated a "No Rafting" area.
Aug-04 The buoys have been replaced in Back Bay (Wolfeboro).  In 2002, the Marine Patrol informed Bizer that the buoys in Back Bay had been deemed obsolete and were not going to be replaced.  That was true in 2002 and 2003.  In the summer of 2004, they were replaced with neither warning nor explanation.  When boating into Back Bay, keep the red spars to starboard (on your right) and the black spars to port (on your left).
Aug-04 - Silver Sands Marina no longer has public boat launching at its facility.
Jun-04 - The USGS has adjusted its datum of Lake Winnipesaukee from 499.92 feet above sea level to 500.00 feet above sea level. Please add 0.08 feet (one inch) to all comments with respect to above sea level (ASL). Full lake, formerly 504.24' ASL is now 504.32' ASL.
Feb-04 - Harborside Restaurant in Center Harbor (F.K.A. Checkers Harbor) has closed its doors. In its place Canoe Restaurant has opened.
Jan-04 - No sooner had we sent the computer disks to the printer than someone told us that the gas docks at the Mountain View Yacht Club are open to the public. They are in Sanders Bay, grid J-8 on Bizer's chart.
