Bizer news of Lake Winnipesaukee

Updated 14-Mar-2024

Version 4 of Winnipesaukee/Garmin is now available. 

Go to http://bizer.com/garmin for the latest progress on Bizer's Garmin project.  *** We now have Garmin DataCards, SD cards, or MicroSD cards pre-loaded with our Winnipesaukee version W4

Bizer has increased its $100 REWARD 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 $250.00. 

No correction to Bizer's map is too small.  We don't care how trivial it is.  Maybe you know of a new No Rafting zone.  Maybe you know of a restaurant accessible by boat that recently opened (or closed).  Maybe you know of a new road that's not on our chart.  Maybe you know of a new cell tower (or other prominant object on land) that is visible from the lake. (Some people navigate by taking bearings on land objects).  email us at Notify19@bizer.com. We really do want to make this a perfect product.  With your help, we might just do it.


BIZER's Surface level of Lake Winnipesaukee

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 2011.  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 or whenever the lake level changes unexpectedly by more than three inches.

Notes:

 


Additions & corrections to Bizer's twelfth edition (2019) Winnipesaukee chart.

Bizer printed two editions in 2019: 12 and 12B.  Prior to 2019, Bizer's folded-laminated chart was produced by printing the map on posterboard and cutting the map into four sections for laminating.  Some boaters commented that the map was difficult to use when crossing from one quarter to another.  For edition 12, which is only available in laminated-quarters, four separate maps were printed.  Each quarter has an 8mm (1/3 inch) overlap with the adjoining map so there is continuity when navigating from one quarter to another quarter. 

Edition 12B is the folded-waterproof version of Bizer's Winnipesaukee chart.  Edition 12B was printed in September, 2019, after edition 12.  It contains only two minor changes from edition 12.
