Happy New Year! (but not New Water Year)

Posted on: January 4th, 2022 by Tim Koch

Welcome to the first week of 2022, at least according to your desk calendar.

For hydrologists, we are already one quarter of the way through the 2022 water year, which began on October 1, 2021.

In the United States, hydrologic water years run from October 1st through September 30th, and are named by the calendar year in which it ends. So, the 2021 water year ended on September 30th 2021 and the 2022 water year began on October 1st, 2021.


There are a couple hydrological things happening in early autumn that warrant celebrating New Water Year’s Day on October 1st.

The first involves snow. Particularly in high mountain settings, snow that falls from October through December might not melt and become stream flow until spring the following year. If water years were aligned with the calendar, the annual water budget would not be balanced. The hydrologic income (i.e., annual precipitation) would not equal hydrologic expenditures. A simplified water budget can be expressed as:

P = RO + ET + ΔS


P = precipitation,

RO = runoff (stream flow),

ET = evapotranspirtation (combined evaporation and transpiration from plants), and

ΔS = change in soil storage (groundwater).

The second reason for celebrating New Water Year’s Day on October 1st instead of January 1st is stream flow. On average, early autumn is when stream flow is at its lowest. The blue line in the image below shows the mean daily discharge of the Esopus Creek at Allaben for water years 2014-2021 (October 1, 2013 to September 30, 2021). The vertical red lines represent October 1st of each year.

It is clear in this chart that early autumn is typically when the Esopus Creek is at its lowest flow of the year. The hot summer growing season, when evaporation and transpiration were at their peaks, has depleted the groundwater storage. Stream baseflow decreases in response to the lowering of the groundwater table. This makes October 1st the perfect time to celebrate New Water Year’s Day.

Do you own property in the NYC West of Hudson Watershed?

Is your property located in a mapped FEMA floodplain?

Do you have an oil or propane fuel tank?

If so you may be eligible for funding from the Catskill Watershed Corporation’s (CWC) Flood Hazard Mitigation Implementation Tank Anchoring Program. This program is designed to help residents and businesses keep their tanks safe from damage and flotation during a flood. Preventing spills helps protect water quality and human health.

Oil tanks up to 330 gallons and propane tanks up to 420 pounds located within the 500-year floodplain of the West of Hudson NYC Watershed are eligible. Larger commercial tanks may be eligible but require CWC Board of Directors approval. If approved the Catskill Watershed Corporation will cover tank anchoring costs whether they are outdoors or in basements. Landowners will hire a contractor of their choice to complete tank anchoring. No cost to applicant.

AWSMP Staff Featured on New Podcast

Posted on: November 19th, 2021 by Tim Koch

AWSMP staffers Tim Koch and Aaron Bennett are featured in the recently released “Views From the Watershed” podcast. The podcast is a self-guided audio tour of the New York City West-of-Hudson Water Supply Watershed, and features many other notable Catskills names.

Tim is in Episode #11 titled “Un-Muddying the Waters.” Recorded at the Main Street bridge in Phoenicia, Tim discusses how a project designed to improve sediment transport was used to reduce flooding on Main Street in a flood prone village built on an alluvial fan. Other topics include turbidity, the importance of riparian buffers, and climate change.

Aaron is featured in Episode 12, “Tough Choices.” From a vacant lot in Boiceville, Aaron discusses the hard decisions faced by flood prone communities in the Catskills, and all over the country. He explains why building flood walls and dredging streams are no longer practical, affordable, or sustainable solutions.

5-Year Flood Event in Oliverea

Posted on: November 1st, 2021 by Tim Koch

The Esopus Creek headwaters and Birch Creek both experienced a 5-year flood event as a result of heavy rains on October 25th and 26th. The McKinley Hollow bridge was briefly overtopped due to downed trees blocking the inlet. Oliverea Road (County Route 47) was closed for a number of hours due to flooding in a low lying area where the road and stream are at the same elevation. Ulster County DPW promptly responded to reopen the bridge and road.

A 5-year flood event is the discharge that has a 20% chance of occurring in any given year, based on statistical analysis of at least 10 years of continuous flow data from a USGS stream gage. The “100-year flood” has a 1% chance of occurring in any given year.

The longer the period of record at the gage, the more accurate the probabilities will be for a flood of a given magnitude. The Ashokan Reservoir watershed is one of the most heavily monitored watersheds in New York State, both in terms of the number of gages and the length of time.

The Esopus Creek gage at Allaben has continuous flow data since 1968 (53 years) and the Birch Creek at Big Indian gage has been in operation since 1998 (23 years). The Esopus Creek at Coldbrook gage has been continuously monitoring flow since 1931 (90 years), with monthly flow data dating back to 1914, when the Olivebridge dam and the Ashokan Reservoir were still being constructed.

The Ashokan Watershed Stream Management Program is continuing to assess this flood event and assisting local highway departments with emergency stream repairs as requested. If you need advise on how to manage flooding or erosion on your property in the Ashokan Reservoir watershed, call the stream program office at (845) 688-3047.

Municipal Officials’ Day, Wednesday, October 20

Posted on: October 18th, 2021 by Leslie_Zucker

Municipal officials from the towns of Shandaken, Olive, Woodstock, Hurley, Lexington and Hunter are invited to attend a 2-hour educational event in Phoenicia on Wednesday, October 20 from 3:00-5:00 pm. The topic will be managing sediment in streams to reduce flooding and erosion. We’ll learn more about how streams transport sediment and how to manage sediment when an intervention is necessary. A certificate of completion will be offered for Continuing Education Credit.

The program starts at the Phoenicia Fire Hall on Route 214 where registration begins at 2:30 pm. We’ll spend a half hour indoors and then move outdoors to the Main Street Bridge where the Town of Shandaken grappled with a massive sediment accumulation and flooding in the 2010s. Sediment management in the Esopus Creek was examined again during a Local Flood Analysis for Phoenicia. Town officials will discuss flood mitigation steps they are taking to improve conditions in a hamlet that is largely in the 100-year floodplain.

Registration is required. Covid-19 safety procedures will be in place for the indoor portion of event. To register, enter your contact information here:

Tropical Depression Ida May Bring Flash Flooding to Watershed

Posted on: August 31st, 2021 by Brent Gotsch
Tropical Depression Ida expected rainfall totals. From National Hurricane Center.

The remnants of Tropical Depression Ida will be passing close to our region Wednesday into Thursday. The National Weather Service is predicting that many locations in the Tri-State area could receive 2-4 inches of rain. As a result, most of the region is under a flash flood advisory through Thursday afternoon. Although major flooding is not expected for the Ashokan Watershed it is still a good idea or be prepared.

Stay up-to-date on current weather information by visiting NYS MESONET, a New York State specific weather forecasting site managed by the National Weather Service and the State University of New York at Albany. Check current stream flow conditions by visiting the NYS Page of the USGS Stream Gage Network. Check the National Weather Service River Forecast webpage for area flood predictions.

Always be pay attention to directives from local authorities especially if they say to evacuate. Be sure to check local County and Town/Village webpages and social media for updated information. Do not drive through standing water, especially in the evening or during low-light conditions as it is often difficult to determine the depth of water on a roadway. The number one cause of death from flooding is from people driving through water that is too deep for their vehicles. FEMA has several excellent resources for preparing for many natural disasters including flooding at its site. The New York Extension Disaster Education Network also has several good resources available.
