Water-quality-monitoring protocols for lakes, ponds, and streams in parks in the National Park Service Inventory and Monitoring Program’s Northeast Temperate Network (NETN) are presented. Protocols consist of a narrative in part I and Standard Operating
Procedures (SOPs) in part II. The narrative in part I includes monitoring objectives, sampling design, proposed sampling sites for each park in NETN and applicable state water-quality standards. SOPs in part II include step-by-step instructions for field methods and data management, including quality assurance and quality control. Part II is intended for use as a manual and reflects SOPs currently in use by other agencies collecting water-quality data in NETN parks. If SOPs are updated to reflect new methods, all older versions of the protocols must be archived.
