Methods are summarized in Claessens et al. 2006. Data through 1999 are from Claessens et al. 2006. Data for 2000 through 2008 are updated using similar data sources. Briefly, precipitation was estimated from precipitation gages within the region. Discharge was calculated from USGS gage data at the Ipswich gage at Ipswich (#01102000). Water supply source, public water export, and amount of sewage exported are based on town level tabular information compiled over time for towns within the basin. All sewage water is exported from the basin, as there are no sewage treatment plants in the basin. ET was calculated by difference (PPT-RO-netExport). For more details see Claessens et al. 2006 All variables were standardized as depth of water per year (mm/yr) to construct the budget, using the area of the Ipswich River watershed (404 km2). That is, total volume of water per time was divided by watershed area and converted to mm/yr. Claessens, L., C. Hopkinson, E. Rastetter, and J. Vallino. 2006.

The principal study site is the Plum Island Sound estuary, its coupled Parker, Rowley and Ipswich River watersheds and the adjacent coastal ocean, the Gulf of Maine. The PIE LTER focuses on how several aspects of global change influence organic matter and inorganic nutrient biogeochemistry and estuarine foodwebs. The inputs of organic matter and nutrients from land, ocean and marshes interact with the external drivers (climate, land use, river discharge, sea level) to dictate the extent and degree of nutrient and organic matter processing and determine the spatial patterns of estuarine productivity and trophic structure. This material is based upon work supported by the National Science Foundation under Grants OCE-9726921, OCE-0423565. Any opinions, findings, conclusions, or recommendations expressed in the material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation. The Plum Island Ecosystems (PIE) LTER site, is located in northeastern Massachusetts, 42.72 N, 70.85 W. The PIE LTER lies at the interface of a thinly soiled, formerly glaciated New England land mass and the highly productive Gulf of Maine. Three watersheds comprise the estuarine drainage basin: Parker (155 km2), Rowley (26 km2) and Ipswich (404 km2). The Ipswich River watershed is highly urbanized with Boston "bedroom" communities encroaching in the headwater region while the Parker is less urbanized and retains a higher proportion of forest. -71.2198 -70.7568 42.8276 42.4965 0 100 meter WAT-IP-HistoricalWaterBudget.csv Annual estimates of the water budget for the Ipswich River watershed, 1931 - 2008.
