2012 SPARROW Models for the Pacific: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow

2012 SPARROW (SPAtially Referenced Regressions On Watershed attributes) interactive mappers are available for 5 regions of the conterminous U.S. These mappers simulate river streamflow, and nutrient and sediment loads and yields, that would occur under long-term average hydrologic conditions for the time period 1999 through 2014, and source inputs that occurred during or near 2012.

2012 SPARROW Models for the Southeast: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow

2012 SPARROW (SPAtially Referenced Regressions On Watershed attributes) interactive mappers are available for 5 regions of the conterminous U.S. These mappers simulate river streamflow, and nutrient and sediment loads and yields, that would occur under long-term average hydrologic conditions for the time period 1999 through 2014, and source inputs that occurred during or near 2012.

2012 SPARROW Models for the Southwest: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow

2012 SPARROW (SPAtially Referenced Regressions On Watershed attributes) interactive mappers are available for 5 regions of the conterminous U.S. These mappers simulate river streamflow, and nutrient and sediment loads and yields, that would occur under long-term average hydrologic conditions for the time period 1999 through 2014, and source inputs that occurred during or near 2012.

2012 SPARROW Models for the Northeast: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow

SPARROW model results of mean daily streamflow and average annual total nitrogen, total phosphorus and suspended sediment load in Northeast US streams. The simulated streamflow represents long-term average source inputs and hydrologic conditions from 1999 to 2014. The simulated loads represent source inputs similar to 2012 and normalized to long-term average hydrologic conditions from 19

2012 SPARROW Models for the Pacific: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow

SPARROW model results of mean daily streamflow and average annual total nitrogen, total phosphorus and suspended sediment load in Pacific US streams. The simulated streamflow represents long-term average source inputs and hydrologic conditions from 1999 to 2014. The simulated loads represent source inputs similar to 2012 and normalized to long-term average hydrologic conditions from 1999

2012 SPARROW Models for the Southeast: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow

SPARROW model results of mean daily streamflow and average annual total nitrogen, total phosphorus and suspended sediment load in Southeast US streams. The simulated streamflow represents long-term average source inputs and hydrologic conditions from 1999 to 2014. The simulated loads represent source inputs similar to 2012 and normalized to long-term average hydrologic conditions from 19

2012 SPARROW Models for the Southwest: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow

SPARROW model results of mean daily streamflow and average annual total nitrogen, total phosphorus and suspended sediment load in Southwest US streams. The simulated streamflow represents long-term average source inputs and hydrologic conditions from 1999 to 2014. The simulated loads represent source inputs similar to 2012 and normalized to long-term average hydrologic conditions from 19

2012 SPARROW Models for the Midwest: Total Phosphorus, Total Nitrogen, Suspended Sediment, and Streamflow

SPARROW model results of mean daily streamflow and average annual total nitrogen, total phosphorus and suspended sediment load in Midwest US streams. The simulated streamflow represents long-term average source inputs and hydrologic conditions from 1999 to 2014. The simulated loads represent source inputs similar to 2012 and normalized to long-term average hydrologic conditions from

Texas Water Dashboard

The Texas Water Dashboard presents USGS real-time stream, lake and reservoir, precipitation and groundwater data for more than 850 USGS real-time observation stations in Texas.

2002 SPARROW Model Results for the Midcontinental Region of North America: Total Phosphorus and Total Nitrogen

SPARROW model results of long-term mean-annual total nitrogen and total phosphorus in streams of the Midcontinental Region of North America. The simulated loads represent source inputs similar to 2002 and normalized to long-term average hydrologic conditions for the period from 1970 to through 2012.

New England Groundwater Level Network, 2017 - Web application

Locations of active wells (at least one measurement during the previous year) in the New England groundwater level network at the end of 2017. The dataset contains 104 wells with continuous water-level measurements (15-minute to hourly measurements), 182 wells with discrete water-level measurements (monthly measurements at most locations), and 95 wells with intermittent water-level measurements.
