Congaree National Park - Appreciating and Learning From What's Been Lost
In September 2023, we visited Congaree National Park located just southeast of Columbia, SC. Only 27,000 acres, it is dwarf-sized compared to most national parks. It is a remnant (11,000 acres) of diverse, old growth forested floodplain that was preserved through the efforts led by Henry Hampton, a local journalist, and incorporated into the national park system in 1976. It includes loblolly pine, bald cypress, sweetgum, american beech, swamp chestnut oak, american holly, water tupelo, dwarf palmetto and more. The tallest loblolly pine is 169 feet tall, and some bald cypress are nearly 500 years old. We took a ranger-led 2.4 mile hike on the boardwalk loop trail that was so informative. The guide was a retired South Carolina Department of Natural Resources biologist who knew the park well. If we had more time we'd have taken the Cedar Creek kayaking trip that would have provided a different vantage point for viewing the park.
There were once 35,000,000 acres of forested floodplain that existed in the southeast and Gulf of Mexico before white settlers began arriving here in numbers in the 1700's. Trees were cut for gain - ships, railroads and buildings, and the lands were drained and converted to pastures, farms and cities. But something was lost too. Floodplains provided natural storage for floodwaters. Floodplain guts (pictured above) are shallow swales that regularly conveyed floodwaters and nutrient rich sediments from rivers that were deposited in the forested floodplains. Oxbow lakes, like Lake Wilson (pictured above), were formerly meandering rivers that migrated downstream and, often during a flood, cut through the neck of the meander, leaving a a semicircular curved lake that provides habitat for waterfowl and fish.
The natural storage that was once provided by forested floodplains has been replaced with engineered, large-scale flood risk mitigation projects involving river channelization, levees, floodwalls and reservoirs all of which. Today's floodplain managers and water resources engineers can sometimes use the principles evident in nature within Congaree National Park's floodplains to reduce peak flows and sediment delivery to lakes and streams through projects that increase natural floodplain storage through reconnecting anthropogenically modified streams to their floodplains using channel plugs, bank lowering, floodplain plantings, and spreaders to create features similar to what the guts (also called sloughs) do naturally.
This quote by William Faulkner beautifully describes a gut.
"The thick black, slow unsigned stream almost without current,
which once each year ceased to flow at all and then reversed -
spreading, drowning the land and subsiding again, leaving it
still richer...." William Faulkner
So while much of our old growth forested floodplains have been permanently lost, this wonderous preserve illustrates naturally what floodplain managers and water resources engineers can attempt to recreate in some locations today. I am fortunate to have had the opportunity to appreciate this pristine forested floodplain and to learn by seeing the principles of how rivers and their floodplains work together in an ecologically beneficial manner.

My Interest and Water Resources Work on New York's Erie Canal
With more than
40 years of experience in New York State’s waterways, Water
Principal Ken Avery has a resume that spans projects from river hydraulics
to ecosystem restoration, flood risk management, dams and levees. Ken
believes that we possess the engineering tools and technology to design,
construct, manage and operate our water infrastructure in a more resilient
manner to yield greater benefits to the public and the environment, while
reducing the risks to life and infrastructure.
Here, he discusses the
past, present and future of the historic Erie Canal System, and provides an
update on how he and the team at Bergmann, an affiliate of Colliers Engineering
& Design, are contributing to important efforts to ensure the viability of
the system for New York residents and visitors for years to come.
Tell us about your
background and what led you to your interest in the Erie Canal.
My interest in the
Erie Canal system spans all aspects of it – its history, the economics and the
technical details. I grew up in Rochester and lived in New York State my entire
life, including going to college there. I’ve always enjoyed the important role
of New York State in American history, as my dad has. And I’m fascinated by how
the early canal engineers were able to use the materials and the engineering
practices they had, which were nothing compared to what we have to work with
today, to build the original canal system. They had timber, quarried rock,
cement and wrought iron to build the original Erie Canal and the numerous
feeder canals. Peter L. Bernstein’s Wedding of the Waters: The Erie
Canal and the Making of a Great Nation does a really good job of
explaining how they accomplished this feat.
Can you explain the
different ways the Erie Canal is used today and how it has evolved?
Today, it’s primarily
used as a recreational waterway for pleasure boats and the towpath is now the
Erie Canal Heritage Trail. The Erie Canal Heritage Trail has
recently been completed and runs parallel to it for most of its length. But in
1825, the canal system started as a four-foot-deep canal, a ditch essentially.
In fact, the first 56 miles of it were built without any locks on a very level,
flat area between Rome and Syracuse, NY. Over the years, there were some
expansions to the canal in the 1850s. It was deepened into seven feet, and that
allowed heavier tonnage to be shipped. In 1918, which seems like it should have
been at the end of the canal-building era, the railroads had become very
powerful so, the thought was that if we increased the tonnage on the canal and
used the materials we have today, you could build the gates of the locks with
steel, which is a much stronger material than timber. The availability of steel
enabled portions of the Mohawk River to be canalized using moveable dams to
create navigation pools between locks located on the river’s edge. That
expansion was the first to use large steel structures, and we have one of those
structures here in downtown Rochester, New York – the Court Street Dam. The
idea was that the Barge Canal system could be a competitor to the railroads.
And as late as the 1960s, that canal system was shipping a payload of annually.
However, the opening of the St. Lawrence Seaway system in 1959, allowed
ocean-going ships to come into the Great Lakes through the St. Lawrence Seaway
project, and that really ended most of the commercial shipping on the canal.
What is the current
condition of the canal?
If you go along the
West River Wall in Rochester, you’ll see that there are sections called
monoliths and these are concrete castings that are maybe 40 feet in length.
You’ll see one monolith that looks to be in good condition. And then the
one right next to it has an incredible amount of deterioration. If you look at the
concrete, you can tell that it’s not broken through the aggregate, but around
the aggregate. That’s an indication of poor quality in concrete construction.
The concrete practices and quality control were nowhere near as good as they
are today. The other aspect of this is that waterway infrastructure is very
expensive to rehabilitate.
The canal also
includes 130 miles of raised earthen embankments that during the navigation
season impound 12 feet of water above the adjacent lands, some of which are
residential. Over the years, in many locations, dense tree vegetation has been
allowed to grow on the embankments, impairing their inspection and assessment.
Bergmann has assisted the Canal Corporation in developing an inspection and
maintenance Guide Book and a Generic Environmental Impact Statement to improve
the condition and safety of these earthen embankments and reduce the risks to
life and damage to nearby infrastructure. This program will require many
years of persistent inspection, evaluation, prioritization and construction to
restore the embankments to a safer and more maintainable condition.
Can you tell us about
the Reimagine the Canals Initiative and our involvement?
Reimagine the Canals was announced in 2019.
It’s a sweeping initiative to see how the canal system can be reimaged for the
21st century. There are five objectives:
- Resilience – Utilize Canal
infrastructure to mitigate summer flooding and eliminate ice jams in the
Mohawk Valley
- Regeneration – Adaptively reuse
infrastructure and surplus land to improve the quality of life in
communities bordering the waterway
- Restoration – Manage the
waterway to restore the natural environment for people and wildlife,
rebalancing a highly compromised ecosystem
- Reuse – Use water no longer
needed for large ships to support new uses such as agriculture and
recreational fishing, and further bolster water- and trail-based
recreation and tourism
- Retrofit – Identify
opportunities to drive operational improvement that will reduce ongoing
operations and maintenance costs and generate revenue
We’re involved in a
number of ways, primarily looking at flood mitigation on the Mohawk River. We
also provided a lot of hydraulic evaluations and flood damage evaluations, both
in terms of the potential flood damage reduction and in flood insurance premium
reductions that could be achieved simply by operating the canal system in a way
where the movable dam gates would be opened in advance of a flood event, and
to release their impounded water. Another aspect that we helped out with is
managing water in the 60-mile pool between Rochester and Lockport to support
recreational sport fisheries.
What advice do you
have for people looking to get into the waterways field?
If you’re interested
in any aspect of water, dive in. Take on part-time or permanent jobs,
take courses in the water field, read the history of great water projects, read
technical literature and read water policy. While on this journey, take every
opportunity to learn more and soon you’ll find what you’re most passionate and
gifted for.

Understanding The Dobbs Supreme Court Decision
- There's no implicit right in the US Constitution or Bill of Rights to end unborn life.
- Therefore, the individual States get to decide how to address the issue of abortion.
- There is a peaceful process in place to amend the US Constitution to include a right to abortion if those who support abortion wish to do so.
- This decision overturns the legally convoluted and flawed Roe v. Wade decision of 1973. The majority could have upheld Dobbs on a 6-3 vote, adding Chief Justice Roberts to the majority, but decided to go all the way and overturn Roe v. Wade.
- Unlike the Supreme Court's Dred Scott decision that helped lead us into The Civil War, this decision, like Brown v. Board of Education, promotes liberty and life to a maligned and underserved class of people.
- It matters greatly who you vote for as President of the United States. Donald Trump, by relying on The Federalist Society to advise him on selecting justices to serve on our federal courts, assured our nation that we would have originalists making important decisions.
- The culture, with the help of science, has become increasingly pro-life, and this decision, rather than breaking new ground in our culture, affirms a gradual change in our culture that favors liberty and more protections for the unborn.

The Inspiration of C. S. Lewis - The Inner Ring
Speaking to college students in this address, Lewis provides advice and warning to young men concerning a temptation specific to the world, after a brief mention of the devil and the flesh. Although he does not refer to a specific scripture,1 John 2:15-17 aligns with his message. He summarizes an exchange between two soldiers and their commanding officer from Tolstoy's War and Peace before launching into a discussion of the phenomenon of an "inner ring". In that conversation, the two junior officers, instead of following the official system of conversation that would have respected the commanding general, followed their own system, and essentially ignored the general who had to wait for the junior officers to complete their conversation before he could speak.
Have you ever noticed yourself being left out of conversations? Do you know what it feels like to be excluded? Who hasn't? Lewis's address has a message for everyone because everyone has at one time or another, felt they've been left out of some inner ring. He notes that these inner rings are constructed by "unwritten systems", and that the deep desire to be a part of an inner ring (and the terror of being excluded) can be a strong driver. We hope to profit from inclusion in the inner ring "...power, money, liberty to break the rules, avoidance of routine duties, evasion of discipline."
His advice is brilliant and true:
- Recognize that the desire and ambition to be part of an inner ring is a danger for two reasons:
- It can cause us to do some very bad things.
- Being governed by that urge for the inner ring is like attempting to fill a sieve with water - it is something that is impossible to do.
- Until you conquer the fear of being an outsider to the inner circle, you'll remain outside the inner circle.
- You can break that desire by becoming a "sound craftsman" in the work you do, which is the longer lasting goal of any profession.
- Finding other people who like one another and enjoy meeting to do things they like to do is something that no inner ringer can ever have - friendship.

The Inspiration of C.S. Lewis: Learning in War-Time
People one generation younger than mine remark that C.S. Lewis was writing to their generation. Lewis wrote this essay during my father's generation, yet I am soaking up Learning in War-Time some 80 years later as if it was written last week. There's something timeless about this Lewis address to students because I am reading this in an age of increased turmoil and totalitarianism in the world and in America.
Lewis, delivering his remarks to college students in 1939, first speaks to the reality that war, because it is a finite object, cannot absorb the entire attention of the human soul. Thus, no matter how badly things are going around us, we were not wired to be entirely absorbed in them. Ecclesiastes 3:11 says that God has put eternity into man's hearts, something far beyond the travails of the present world.
He moves on from there to emphasize that our work of learning (whether we are in school or college or engaged in a career or ministry) becomes a spiritual act if offered in humility to God. He encourages them not to let their emotions and nerves make them think that their situation, mired in the suffering of WWII, is more abnormal than it is. Those same words need to be heard in my heart today. Sure, there is much to grieve and much to be alarmed about, but Lewis encourages his students with three defensive mental exercises with which to combat the war (or the equivalents of war we experience today). These enemies are:
- Enemy #1 - Excitement - Don't wait for distraction to end to get to work. He remarks that the people who work hard, including under unfavorable conditions, will achieve much. Sure, evil seems to be thriving and there's plenty of distractions but if we wait for the distractions to end, they won't, and we will have achieved nothing. Instead, we could have been about doing good in this world.
- Enemy #2 - Frustration - Lewis encourages his listeners to instead of saying "No time for that" or "Too late now." or "Not for me" to put the future in God's hands. He reminds us that working moment to moment "as to the Lord" since the present is the only time in which duty can be done or grace received. Live for today.
- Enemy #3 - Fear - Although the threat of death and pain was incredibly real for Lewis's listeners, he reminds them it's not a question of life or death for us but only one death or another. Being aware of our mortality is useful and was considered a blessing by great Christians of the past. Lewis reminds us that in this world we're on a pilgrimage, not trying to build of a utopian society on earth.
