New Hampshire Lake Ice-In and Ice-Out Records

Ice out at Highland Lake, Andover, NHThe NH NHDES VLAP began tracking Lake ice-in and ice-out dates in 2011 as there was no central repository for this information in New Hampshire. Many New Hampshire lakes have historical ice out records dating back to the early 1900's, Lakes Sunapee and Winnipesaukee to the 1880's, but not as much data exists for ice-in records. Tracking both ice-in and ice-out allows the determination of total ice cover days which is another important part of tracking physical, chemical and biological changes to lakes over time. With the erratic weather conditions experienced in recent years, the information can also help track climatological shifts and trends.

"Ice-out" is the term typically used to describe when the ice leaves a lake in the spring. Some consider this to be when the ice has melted and broken up enough to navigate a boat from one end of a lake or pond to the other, or when the lake is completely free of ice. Although ice-out definitions may vary slightly from lake to lake, the important thing is consistency and utilizing the same method to determine ice-out for your lake each year. "Ice-in" is the term used to describe when ice covers a lake in the fall. Ice-in can be more difficult to determine but typically is when the lake is completely or nearly completely covered with ice, however a thin skim of ice is not considered ice-in.

VLAP currently has records for approximately 50 New Hampshire lakes and hopes to add additional lakes to the database. To enter your lake's ice-in and ice-out data, utilize the new online form at forms.nh.gov/onlineforms/?FormTag=NHDES-W-07-028. Once the data for you lake have been entered, historical records are stored electronically and area available upon request for use in lake association publications, scientific research and articles. For additional information, please contact Sara Steiner, VLAP Coordinator, at sara.steiner@des.nh.gov. If you experience any technical problems with the new form system, including sign-in issues, errors and general instruction on using this system, please contact BusinessOneStop@doit.nh.gov.
