A Walk in the Gorge, a Seiche and Stranded Fish©

You never know what you are going to find when you step outside and into the wilderness, sometimes you find nothing at all, and sometimes, well, you find strange things, maybe even things that you have never seen before.  And it always starts with a walk in the wilderness, or in this case a walk in the gorge...

 

A Walk in the Gorge...

Last weekend we decided to go on a walk with Boy Scout Troop 285, along the lower Niagara River.  The day started out cold and overcast, but by about 3:00 pm, it was sunny, without a cloud in the sky, and it was almost 60oF (16oC).  We started walking at the top of the cliffs along the gorge, from Whirlpool State Park, on the American side of the river, before walking along the gorge by the river.  This is a great walk and the trail along the river can be reached by climbing down almost 300 feet (91 meters) of stairs built into the cliff sides along the gorge.  When we got down to the riverside, we turned west to walk upriver to the area of the Whirlpool.

A Seiche...

 

How wind driven seiches occur, a NOAA illustration, found HERE.


So, “what is a seiche”, you might ask?  That is a good question!

 

A seiche (pronounced “saysh”) is caused, according to the American National Oceanic and Atmospheric Administration, or NOAA, when strong winds and rapid changes in atmospheric pressure push the water from one end of a body of water to the other end, raising the level of the water and causing flooding.  When the wind stops the water quickly returns to its original level and the flooding, literally, just drains away!  Lake Erie is known for seiches, particularly when strong winds blow from the southwest to the northeast1.

 

The day before our walk in the gorge, on Friday, March 26, 2021, the Western New York area experienced strong winds, blowing from the southwest, which caused a seiche.  According to the National Weather Service the “WATER LEVEL AT BUFFALO NOS GAGE REACHED 8.4 FEET ABOVE LOW WATER DATUM”; 8.4 feet (2.6 meters) above low water level is a lot of water being pushed towards the Buffalo, New York end of Lake Erie and then down the Niagara River!

 

Where we found evidence of a seiche.


It was when we got to the shelf of rock, which is across from the Whirlpool, that we found evidence of the seiche.

 

Stranded Fish...

All the water that was pushed to the end of Lake Erie had to go somewhere, and the somewhere it went, was down the Niagara River.  Because of the seiche, the water level below Niagara Falls had risen enough that fish were able to swim above the rock ledge which is across from the Whirlpool – a ledge that is usually several feet above water level!  When the winds stopped blowing, the seiche ended and the water in the western portion Lake Erie dropped back to its normal level, and the flood waters in the Niagara River receded so quickly that there a lot of fish got caught in rock pools and cracks all over this ledge!

Most of the fish were dead and all appeared to be Rainbow Trout or as they are also known Steelhead Salmon, (oncorhynchus mykiss)2.  Rainbow Trout and Steelhead Salmon are the same species, but they look different and have vastly different lifestyles.  Rainbow Trout spend their entire life in freshwater, and are green, blue, and yellow, fading to silvery white on their bellies, with a horizontal pinkish-red stripe running from their tails all the way to their gills, and with black spots along their backs.  Steelhead Salmon are anadromous, which means that they spend the first two to three years of their life in freshwater, before migrating to the ocean and then living for two to three years in saltwater, before returning to the freshwater river of their birth to breed.  They are silvery or brassy colored as adults and are not as colorful as their fresh-water-only cousins.  Adult Rainbow Trout and Steelhead Salmon range in size and weight and while they can reach up to 45 inches (114 cm) in length, they are usually much smaller.  Larger Rainbow Trout and Steelhead Salmon can weigh more than 50 pounds (22 kilograms), but usually their weight is 8 pounds (almost 4 kilograms).  Steelhead Salmon, since they spend part of their life in the ocean, however, are usually larger than Rainbow Trout.

Interestingly, Rainbow Trout and Steelhead Salmon are not native to the east coast and the inland waterways of North America, they are originally native to the Pacific Northwest coast of North America and according to Richard D. Moccia and David J. Bevan, in “The Rainbow Trout”, it is “generally accepted that the first movement of rainbow trout occurred to New York State in 1874 from a native spring spawning stock from Campbells Creek on the McLeod River, California” and that the person who first brought the fish to New York state was a fish culturist named Seth Green.  Rainbow Trout are now found in eastern North America throughout the Great Lakes Basin and in the Canadian provinces of Ontario, Newfoundland, New Brunswick, and Nova Scotia.

Not all the fish in the rock pools were dead, however, and we were able to capture five and release them back into the Niagara River.

All in all, it was a great walk, the scenery and the weather were fantastic, and I got to see things I had never seen before; I can’t wait to go back again!
