NHDES’ Real-time Lake and River Level Data Web Portal Gets Major Interface Upgrade

It’s been several years in the making, but NHDES Dam Bureau is excited to announce the release of its new and much improved web portal for Real-Time Data and Information for Watersheds in New Hampshire. The old Real-Time Data page served faithfully for almost 20 years, allowing public access to data and graphs of many hydrometeorological parameters, such as lake and river levels, throughout New Hampshire. But time marches on, as do website standards and IT security protocols.

In the new web portal, users will be greeted with a much more dynamic map interface and interactive plot interfaces. The many user options for viewing/downloading data and information are laid out in the Public Webpage Instructions on the homepage. For automated data retrieval, the new web portal has a built-in publicly accessible Application Programming Interface, or API. Instructions for use of the API are also available on the homepage.

The old real-time data webpage will be discontinued in January 2023.
