Where is the Delaware River deepest? New map poster shows 113-foot answer

Where is the deepest part of the 330-mile Delaware River? Where it is also widest, where the river meets the Delaware Bay? Try Narrowsburg, New York. A new map has been published showing the mysterious contours of what is called the “Big Eddy Narrows.”

The river, the longest free-flowing river east of the Mississippi, is 113 feet deep at River Mile 290, counting from Delaware Bay, and visible from the bridge connecting Pennsylvania and New York.

The Delaware River’s average depth is only four to five feet, although holes of 12 to 18 feet are not unusual.

A diver with a local search and rescue team said no light penetrates the bottom at all.

Made a map poster

The map is available as an 11-by-17-inch poster that its creator has donated to benefit the non-profit Upper Delaware Council (UDC), announced UDC Executive Director Laurie Ramie.

The map was developed by Lisa Glover of Honesdale, who became enthralled with this unique, local claim to fame of the Delaware River and contacted the UDC.

Although one might muse that the hamlet of Narrowsburg should have been named Deepestburg, its name is derived from its other distinction of being the main stem’s narrowest part. The river courses through a rock canyon before the bridge, where it is only 200 feet wide.

Where to see it

The Big Eddy Observation Deck on Main Street in Narrowsburg has an interpretative sign telling these distinctive topographic features. Here the public also finds a good place to watch for bald eagles as rowboats, canoes, kayaks, and rafts go by.

Perhaps very few people paddling by or on shore looking at this scenic part of the river are aware of the fantastic underwater depth.

This very deep part of the Delaware also is easily seen from the Darbytown Access on the Pennsylvania side.

The interpretative sign at the deck offers two theories of how the 113-foot hole was created. The first is that a long-drowned “plunge pool” was created from a glacial waterfall. The other theory is that a pothole was formed by tumbling rocks scoured out through erosion.

A whirlpool is often visible at the Big Eddy, where the deepest point is located just downstream from the narrows.

Log rafts spun like tops

The deeps at Narrowsburg have been known for a very long time, impacting 19th century log rafters. The Wayne County Herald’s Feb. 20, 1873, edition reported that J.I. Appleby and J.E. Miller, of Narrowsburg, out of curiosity took soundings of the river from a boat. They concluded the river was 101 feet. “Rafts in coming down the Delaware are frequently drawn into this eddy and sometimes detained for days,” the article reads. “Whenever the wind is blowing with any force, rafts are sure to be drawn into this eddy where they have to remain until the wind calms.”

The Herald republished an unattributed column from The Middletown Mercury on Jan. 20, 1881, stating that log rafts caught in the Big Eddy “may spin around like a top for an hour.” Rafts so caught could create a river traffic jam of a hundred rafts. “I have seen 500 rafts in here at one time, some of them on top of each other, and some turned up on edge, and others bottom side up,” the columnist penned.

Extensive research

The UDC press release states that Glover read articles from the UDC’s “The Upper Delaware” newsletter which led her to interviews with National Park Service divers who had measured the hole. Glover also found various illustrations.

She spoke of her desire for an accurately detailed map of the river bottom with the hope of potentially solving the mystery. Although topographic maps exist showing the elevation of landforms above “sea level,” bathymetric maps show depths of landforms below water.

Glover, in her research, discovered that the U.S. Geological Survey (USGS) had published a LiDAR scan of the Delaware River in 2020 and reached research scientist John Young, who provided a digital map focused on the Big Eddy section, the press release states.

Obtaining a map

From her research, Glover designed a topobathymetric color map with 10-foot contour lines and to-scale cross sections of The Narrows and The Deeps, printed 50 copies, and offered a stack to the UDC to share with the public as a fundraiser.

The Big Eddy Narrows poster is available for a $20 donation to the UDC.

Payment must be by check or cash. Add $3 for mail orders.

Glover is affiliated with Highlights for Children, the Stourbridge Project, the Wayne County Arts Alliance and the Center on Rural Innovation, for which she is their Placemaking Fellow.

She holds a bachelor’s degree in architecture and a master of engineering degree from Lehigh University and likes to use a paddle board. Her website is lisathemaker.com.

How much snow will we get? Delaware under winter weather advisory

Delaware is under a winter weather advisory for the weekend, with snow and bitterly cold conditions expected.
Snowfall of 1 to 5 inches is possible across the region, with higher amounts of up to 6 inches in New Castle County.
The snow is expected to begin Saturday night and continue through mid-morning on Sunday.
Bitterly cold temperatures and low windchills will follow the snow, lasting through early next week.

Gas the snowblowers and get those shovels out because snowfall is headed for Delaware.

Snow is forecast for this weekend with bitterly cold conditions then settling in through early next week.

On Saturday, Dec. 13, the National Weather Service in Mount Holly, New Jersey, placed all of Delaware under a winter weather advisory and the Delaware Bay under a gale warning.

Meanwhile, Philadelphia and areas surrounding the city are under a winter storm warning.

Here’s a look at what to expect with the Delaware weather forecast for Saturday, Dec. 13, through Sunday, Dec. 14.

Delaware weather radar

When will it snow?

A period of snow is expected the night of Dec. 13 through mid-morning Dec. 14, according to the National Weather Service.

This may start as some light rain or a rain/snow mix south and east of I-95 before quickly changing to all snow. Snowfall intensity may increase for a time early in the morning on Dec. 14.

About 1 to 5 inches of snow across the region is possible. While the location of where a zone of higher amounts can occur is less certain, the greatest chances for this is mostly across the I-95 corridor, the weather service said.

The snow will begin falling around 11 p.m. in Wilmington while snowfall will begin in the central portion of New Castle County by midnight and the southern part of the county by 1 a.m., according to the NWS.

The northern part of Kent County can expect snow to start falling around 2 a.m. and areas around Dover by 3 a.m.

Snow will begin in the southern part of Kent County and northern portion of Sussex County around 4 a.m.

Most of Sussex County can expect snow at 5 a.m. while the southern part of the county will see snowfall by 6 a.m. Areas around Rehoboth Beach can expect snow by 7 a.m.

How much will it snow?

That will depend where you are in Delaware.

A total of 1 to 5 inches of snow across the whole area. There could be a zone of 5-plus inches near I-95 into southern New Jersey and northern Delmarva, where snowfall rates near 1 inch per hour are also possible, according to the NWS.

Snowfall intensity may increase for a time early Sunday morning, forecasters said.

Most parts of New Castle County can expect up to 4 to 6 inches, while Kent County could see up to 1 to 2 inches in some areas. Sussex County should expect at least an inch, the NWS said.

Delaware snow forecast

Here’s an AccuWeather town-by-town snow forecast for this weekend in Delaware:

New Castle County

Middletown: 3 to 6 inches
New Castle: 4 to 6 inches
Newark: 4 to 6 inches
Pike Creek: 4 to 6 inches
Wilmington: 3 to 6 inches

Kent County

Dover: 2 to 4 inches
Felton: 2 to 4 inches
Harrington: 2 to 4 inches
Milford (In Kent and Sussex counties): 2 to 4 inches

Sussex County

Georgetown: 1 to 3 inches
Millsboro: 1 to 3 inches
Rehoboth Beach: 1 to 3 inches
Seaford: 1 to 3 inches

Snow impacts

Here are some of the likely impacts of the weekend weather, according to the NWS:

Snow-covered roads and slippery conditions possible the night of Dec. 13 and the morning of Dec. 14.
Rain to snow could reduce the snow totals some. In addition, any pre-treating of surfaces would get initially washed away on the night of Dec. 13.
Hypothermia or frostbite could occur with prolonged exposure and lack of proper clothing. Some impacts to infrastructure are possible the night of Dec. 14 through Dec. 16.

Windchills reach single digits, gale warning

When you’re outside shoveling, make sure to bundle up because it’s going to be bitterly cold Dec. 14 into Dec. 16.

Bitterly cold conditions will arrive Dec. 14 and continuing through early next week with the coldest time frame the night of Dec. 14 through the night of Dec. 15. Air temperatures on Dec. 16 stay below freezing across the region.

By Sunday night, the windchill will make it feel like 6 degrees in Wilmington, 4 degrees in Dover, and 5 degrees in Rehoboth Beach.

Many areas will not get above freezing from Sunday through Tuesday until a warming trend begins Wednesday, Dec. 17.

Peak gusts of 25 to 40 mph will be present Sunday into Sunday night which will result in very low windchill values.

Areas of blowing snow are possible, which may result in roads becoming snow-covered again and reduced visibility at times, according to the NWS.

Wind gusts between 35 to 40 knots are probable on the Delaware Bay and the New Jersey and Delaware Atlantic coastal waters along with hazardous seas. Areas of freezing spray are possible the night of Dec. 14 and Dec. 15.

How do I stay safe in the snow?

It is strongly recommended that you stay at home when it snows.

But if you absolutely need to drive, make sure you bear in mind the following safety tips:

Drive slowly. Snow and ice can decrease traction on the road, so be sure to reduce your speed.
Avoid using cruise control.
Increase following distances from the usual two seconds to roughly five to six seconds, as it’ll take longer for you to come to a stop on snowy roadways.
Make sure you have at least a half a tank of gas in your car.
Make sure you have an emergency driving kit in your vehicle. Items should include blankets or sleeping bags, extra warm clothing, first-aid supplies, drinking water and shelf-stable food items like protein or energy bars and trail mix.

If there’s a chance you’ll have to shovel your driveway or walkway this weekend, make sure you pay attention to the latest weather forecast, wear appropriate clothing and boots, and drink lots of water.

Make sure you also pace yourself as you’re shoveling. Check if you feel any pain or soreness and have your phone close by in case of an emergency.

What should I do to keep warm?

With winter fast approaching, residents are recommended to take the necessary steps to stay safe as the weather turns cold.

This includes making sure your homes “can be safely heated” and you always have crucial items on hand in case of an emergency, including nonperishable and pet foods, water and medicine.

Delawareans are also encouraged to have a driving kit in their car this winter.

Items should include blankets or sleeping bags, extra warm clothing, first-aid supplies, drinking water and shelf-stable food items like protein or energy bars and trail mix.
