Nitrogen, phosphorus, and sediment loads to the Great Bay Estuary are a growing concern. In the 2006 State of the Estuaries report (NHEP, 2006), the New Hampshire Estuaries Project (now called the Piscataqua Region Estuaries Partnership or PREP) calculated the nitrogen load from tributaries to the Great Bay Estuary using data collected by the NH Department of Environmental Services. PREP needs to update this indicator for the 2009 State of the Estuaries report. Therefore, the purpose of this study was to collect representative data on nitrogen, phosphorus, and suspended sediment concentrations in tributaries to the Great Bay Estuary in 2008. The study design followed the tributary sampling design which was implemented by the New Hampshire Department of Environmental Services between 2001 and 2007 so as to provide comparable data to the previous loading estimates.
