Practical pathways for protecting headwater streams in urbanizing areas Practical pathways for protecting headwater streams in urbanizing areas
Headwater streams are diverse ecosystems and important sources of water and dissolved and particulate resources to the downstream river network. However, across the world, they are rapidly being degraded or lost through human activities, particularly urban development. This degradation and loss have negative consequences for the structure and function of headwater streams, as well as...
Statistical streamflow comparison of current and historical 30-year periods for selected streams in New Jersey Statistical streamflow comparison of current and historical 30-year periods for selected streams in New Jersey
As the population of New Jersey increases, supplying adequate drinking water to meet demand remains a high priority. To better understand potential streamflow trends over time, the U.S. Geological Survey completed a study comparing low flows at continuous- and partial-record streamgages in New Jersey between a historical period (1950–79) and a current period (1990–2019). Fourteen...
Estimating daily public supply water use by drinking water service area in New Jersey Estimating daily public supply water use by drinking water service area in New Jersey
This report, prepared in cooperation with the New Jersey Department of Environmental Protection, presents a method for estimating daily public supply water use by drinking water service area systems for New Jersey. The ability to accurately estimate daily public supply water use could help water supply planners in New Jersey better understand and manage the state’s limited water...
