Guidance for Submittal of Water Quality Data for Development of the 2024 303(d)/305(b) Intergraded Report

The New Hampshire Department of Environmental Services (NHDES) is preparing for the 2024 Surface Water Quality Assessment process, as required by Sections 305(b) and 303(d) of the Clean Water Act. The first step in this process is to make sure that NHDES has as much available data as possible on which to base our water quality assessment decisions. To that end, NHDES encourages anyone who has surface water data/information, to submit it to NHDES electronically.  For inclusion in the 2024 Surface Water Quality Assessments data must be submitted no later than January 27, 2023. 

The Guidance for Submittal of Surface Water Data/Information further describes the role of 305(b)/303(d) assessments as well as instructions for data submittal.
