DEP PRESS RELEASE:
Department of Environmental Protection and U.S. Geological Survey Announce Installation of New Stream Gauge in Lower Esopus at Lomontville
Gauge in Lower Esopus Creek Will Provide Important Data for Future Stream Projects
Data on Flow and Turbidity is Viewable on USGS Website
The New York City Department of Environmental Protection (DEP) and the U.S. Geological Survey (USGS) today announced that a new stream gauge was installed this month along the lower Esopus Creek at Lomontville, roughly 6 miles below Ashokan Reservoir. The gauge will provide flow and turbidity data, which will be posted in near-real time to the USGS and DEP websites. As part of the installation project, the ability to measure turbidity was also added to an existing gauge further downstream in Mount Marion, and that data will also be posted on the USGS and DEP websites.
The Lomontville gauge was among the terms of a consent order signed in late September by DEP and the state Department of Environmental Conservation. The order required the gauge at Lomontville to be installed within a year. The City and USGS installed it within roughly six weeks. The new stream gauge is part of a national network – including roughly 40 gauges throughout the Catskills – that constantly gathers scientific data to better understand the hydrology of local streams. The gauges also help forecast stream flows, which enhanced an important flood-warning network that protects life and property across the region.
“Scientific data collected by the new gauge will help stakeholders along the lower Esopus better understand how the creek reacts to normal flows and extreme storms, including the resulting fluctuations in turbidity at different points along the creek,” DEP Commissioner Carter Strickland said. “The gauge will also provide valuable information when water is released from Ashokan Reservoir to help ecology and support recreation, enhance flood protection ahead of large storms, and protect the water supply. That information will be easily accessible to the public, underscoring DEP’s commitment to be transparent about all its operations in the Catskills and Hudson Valley.”
“Data from the Lomontville stream gauge will provide critical information to better understand the water resources and suspended sediment transport in the Lower Esopus Watershed,” said Ward Freeman, Director of the New York Water Science Center for USGS. “This will be part of a network of almost 8,000 USGS stream gauges across the nation used by water-resource professionals to better manage and protect the resource. This stream gauge will also provide supplemental data useful in National Weather Service River forecast operations at the Mt. Marion forecast point downstream.”
The long-term data provided by the stream gauge will help in the development of a stream management plan for the creek and will enhance the environmental review that is about to begin. DEP has committed to fund the development of the plan, as well as provide $2 million for stream projects to improve the flow and the banks of the lower Esopus. Understanding the flow of the creek will help with the design of those stream projects. The gauge will also complement DEP’s weekly water-quality monitoring of two other sites along the lower Esopus – just above the Sawkill Creek and at the Saugerties Beach – that provide important data about creek conditions downstream of the reservoir.
