Darby Creek: One of the Last Great Places


What is so special about Darby Creek? … Well, nothing! Yet, that is precisely what is so special about Darby Creek.

Darby Creek is actually comprised of two tributaries – Big Darby Creek and Little Darby Creek. These two creeks flow about 80 miles through present-day west central Ohio. These two creeks were just typical ordinary small streams 200 years ago. They were nothing unique or special; actually they were very commonplace in what was called The Northwest Territory by early American pioneers. Darby Creek was no different than hundreds of miles of similar creeks that stretch across hundreds of miles of hardwood forests northwest of the Ohio River. The receding glaciers, from about 11,000 years before, left this part of the land with paths cut though the gently rolling hills and great expanses of glacial till to form the original courses of these streams. In time, hardwood forests covered much of the landscape. As early explorers came from the original American Colonies they found this land full of animals, natural resources, and opportunity. Thousands of pioneers moved through and into this area. The first “National Road” was built to accommodate migration of settlers and the flow of commerce through Ohio, Indiana and Illinois. (This pioneer highway actually crosses both Big and Little Darby Creeks.) These pioneers brought “civilization” to the area. Today, that great expanse of deciduous forest interlaced with clear flowing creeks has been replaced by productive agricultural areas, industrialized cities, and homes to millions of descendants of those pioneers. This transformation has been so complete that some ecologists claim that in the state of Ohio only .004% of the state’s original ancient forest remains.

Because of colonization, great change came to the creeks that flowed through this vast wilderness. The water flow of the creeks continued, but the interface of land and stream (the riparian corridor) was significantly altered in most areas. Forests were cleared to make room for croplands and urban areas. This affected the local climatic conditions along the waterways. Agricultural runoff and industrial and domestic pollutants entered the water. The habitats for many species of wildlife became altered. The habitat required for the survival of some species of fauna or flora was entirely lost. In some waterways, stream flow was altered by channelization, building of dams, or the draining of wetland areas. As the end of the 1900s approached, there were only a few remnants of the once vast network of streams with their accompanying riparian corridors that remained in the same condition as they had existed for centuries before. Darby Creek is one of those very significant remnants.

Although the forest along the creek is not a virgin forest, a corridor of deciduous forest does continue to grow along much of the banks of Darby Creek. This creek is home to 98 species of fish (slightly over 100 species existed prior to colonization; today, perhaps five of those are endangered). Mussels, which are very sensitive to environmental change or pollutants, exist in nearly the same of number of species as they did 200 years ago – 44 species. But today, two of them are endangered. The creek and its riparian corridor are home to 170 species of birds, and 34 species of mammals. When compared to the seemingly countless other streams and creeks, Big and Little Darby Creeks are, unfortunately, very unique and very valuable because of their biodiversity.

Darby Creek’s scenic beauty and biodiversity has been appreciated by many people in the past few decades. After a long political battle, grassroot efforts were successful in preventing the construction of a dam on Big Darby Creek for a municipal water supply. As a result of those efforts, Darby Creek was further protected when the State of Ohio designated it as a State Scenic River in 1984. Ten years later, it was became a National Scenic River. In 1991, because of the ecological health and biodiversity of the stream an international organization, The Nature Conservancy, designated Darby Creek as one of the dozen “Last Great Places” in the western hemishere.


The Real Value of Darby Creek

Currently there are over 30 organizations, varying from citizen groups to government agencies, which help preserve Darby Creek. Hopefully they will continue in the future. But there have also been groups of people who would readily flood the creek for municipal or private interests. Farmers and urban developers could try to reverse or nullify the environmental protection policies that currently help protect the quality of the waters that feed the stream.

Is the worth of Darby Creek determined by a dollar value for its biodiversity? Can a ledger book tally the expenses for environmental protective measures opposing profits from agricultural use in addition to real estate value for urban and residential developments and infrastructure?

What is the cost to continue maintenance of Darby Creek as one of the last remnants of an ecological environment of meandering streams that interlaced through hundreds of miles of pioneer wilderness? Before such a cost could even begin to be calculated, the real value of this creek needs to be evaluated. What is the value of biodiversity? What is the value to prevent a specie from becoming extinct? What is the value to the attributes of Darby Creek and its accompanying riparian corridor? What value is there to Darby Creeks ecological system or even any eco-system?

In an address to the Ohio Valley Regional Conference in 1925, the Dean of the School of Science at Purdue University, Stanley Coulter, declared that “we began to realize that scenery–our rivers and lakes, our hills and mountains our fertile plains and forests, our peaks of privilege, whence we could see great vistas and glowing sunsets and myriad stars–is our greatest natural resource.

Thoreau asked, “What would it profit if man gained a whole continent, but in the process lost contact with the wellspring of human renewal?”

Richard Lieber, the first director of the Indiana Department of Conservation, while explaining the need for states to protect and preserve natural tracts of land as state parks declared, “Without vision a land will die. Without inspiration we remain disconnected from the immortal order of all things.” On another occasion, in 1941, he said “Converse with nature restores happiness; communion with its mysterious forces, Antaeus-like, fills us with renewed strength and rids us of fear. It is the land and all it contains which performs the miracle.”

What is the value of this emblematic stream named Darby Creek?

Perhaps the answer lies within each one of us.


(Footnote: Antaeus was a Greek mythological giant who seemed invincible until he challenged Hercules. Antaeus was repeatedly thrown to the ground by Hercules but he seemed to be constantly rejuvenated and continued the wrestling match – slowly tiring his opponent. Hercules eventually realized that the earth, Gala, Antaeus’s mother, was the source of his strength. Hercules need only hold Antaeus up off the ground  until his strength expired.)

Some sources have been very academic, while others have more laymen in terms yet informative, and a couple offered little new information. As I read the information, I gathered a list of attributes or information about creeks in general, or Darby Creek specifically, that could be illustrated in photographs. The list also includes information about Darby Creek that could be used in captions. Here is the list that I compiled (which is not in any particular order):

- Darby Creek headwaters are northwest of Maryville, OH.
- Darby Creek confluence with the Scioto River is at Circleville, OH.
- Darby Creek Watershed (comprised of Big Darby Creek, and Little Darby Creek, and a dozen small tributaries) drains approx. 557 square miles.
- Darby Creek is approx. 80 miles long (78-84 miles long depending on the cited source of information).
- It contains 98 species of fish currently, probably just over 100 species at the time of colonization.
- It contains 44 species of freshwater mussels, it contained “over 40” prior to colonization.
- It is fed by coldwater springs and streams, and underground seeps at its headwaters.
- 84 miles of Big and Little Darby Creeks became a State Scenic River on 22 June 1984.
- 84 miles of Big and Little Darby Creeks became a National Scenic River on 3 October 1994.
- It was originally called “Olentangy” by the Native Americans; later it was renamed in honor of a Native American. (Another larger nearby river is currently called the Olentangy River.)
- Darby Creek currently is home to 170 bird species, 34 mammal species, and 100 diatoms.
- Over 30 organizations help preserve it.
- Rivers and streams are “lotic” habitants – they are running water. Lakes and ponds are “lentic” habitats because they are standing water.
- All the rivers and streams in the world contain only .0001% of the Earth’s water. Ground water contains about 5000 times as much water (.5% of the Earth’s water).
- Oceanologists and limnologists are very concerned with light and how far it vertically penetrates into the waters they study.
- The movement of water – direction (vertically as well as horizontally) as well as velocity is an important factor to the ecological environments in a stream.
- Hardwood forests once covered the eastern United States so that a squirrel could go east from Indiana to the Atlantic Ocean and never step onto the ground.
- The geology of the Darby Creek area is apparent in wintertime since the leaves are off of the trees and the creek has cut into hillsides and parts of the fast-flowing creek is down to bedrock.
- 42% of the precipitation over North America becomes runoff and carried by rivers to the sea.
- Erosional effects are dominant in smaller streams near the headwaters; deposition of materials is greater in larger rivers and in the confluence into the oceans.
- Stream Order: 1sst order has no tributaries; 2nd Order is fed by 2 or more 1st Order streams: 3rd Order is fed by 2 or more 2nd Order streams; etc.
- Concerning water flow: “Turbulent” is characterized by irregularity. Neighboring water units move in different directions and at different velocities.
- Velocity and turbulence of the stream, along with the size, shape and specific gravity of the alluvium debris, determines how long and how far rocky debris is carried. (Alluvium is rocky debris)
- Within any typical section of a smaller order stream altering areas of “riffles” and “pools” are common. Each area has varied ecology.
- A canopy of riparian forest affects the balance of autotrophy and heterotrophy. (autotrophy – high in photosynthesis activity; heterotrophy – high in energy gained from organic degradation, such as carnivory, herbivory, omnivory, and microbial decay.)
- The balance of autotrophy and heterotrophy can be seasonal; leaves on trees can block sunshine or in the autumn, leaves fall into stream and decay.
- Algae growth can peak in spring before trees leaf out.
_ It may seem that some animals prefer less turbulent waters, such as crayfish, but the reality is that they select low turbulent areas by day under rocks or vegetation to avoid predators; they become active in the open turbulent waters by night.
- Large pieces of wood become lodged and are “stored” in upstream areas for very long periods of time. Their slow degradation serves as a source of FPOM (fine particulate organic matter) food source for downstream communities.
- Leaves fallen from trees are a valuable nutrient source. Small shedder animals bite and chew the leaves, but their inefficient feeding creates small bits and fine particles with much surface area for bacteria to feast upon. Decomposing leaf matter also leaches DOM (dissolved organic material) into the stream’s water.
- A few mussels or mussel shells need to be photographed.
- Animal activity is high along the riparian corridor. Show mammals or mammal trails.
- Riparian zone is one of the fifteen terrestrial biomes of the earth.
- The meandering course of a stream dissipates stream energy.
- Riparian vegetation reduces soil erosion. It also helps filter pollutants from surface water runoff via biofiltration.
- A canopy of vegetation along a stream shades the water mitigating changes in water temperature.

Introducing Darby Creek Project

What is Darby Creek?

Portions of Darby Creek are designated as State and National Scenic Rivers. Because of its bio-diversity, The Nature Conservancy, in 1991, designated Darby Creek as one of a dozen “Last Great Places” in the western hemisphere. This creek is reminiscent of a vast ecosystem of hundreds of miles of meander-ing creek that existed in the forested glacial till areas of Indiana and Ohio from pre-colonization times.



Why photograph Darby Creek?

“A Glimpse of Darby Creek: One of the Last Great Places” is a linguistically-based fine art project. The project has a depictive subject intent - to show the aesthetic and ecological significance of the Darby Creek area. The experiential outcome intent will allow the viewer to experience the beauty and character of Darby Creek and become aware that many beauties of nature may already be close to them, but simply overlooked.




How is the Darby Creek area to be photographed?

The formal qualities of the images are paramount to achieve the desired experiential outcome intent. The color images will be recorded using tilt-shift lenses and long telephotos on a DSLR camera to create a unifying formal characteristic throughout the project of selective focus to direct the viewer's attention to key elements in the scene. Color and tonal value will also be important formal qualities within the images. HDR imagery will occasionally be used.



Thoughts about Darby Creek:

The Darby Creek waterway has existed since the last ice age began to melt 12-13 thousand years ago. The area has experienced slow climatic and ecological changes since then. It was once a small insignificant part of a vast wilderness that existed until just a couple of hundred years ago when man began to colonize the area. But what is unique about the Darby Creek area is that there still remains enough of once existed to give a glimpse of the natural order of things as they existed under the natural laws given by their creator. It is a remnant area of what was once a vast wilderness. Now, the creek currently runs through countless farms and near many towns and cities that were once forests.

Just as a city or town has a personality or character which is the sum of the people who live in the town, the creek has a character which is the sum of its inhabitants - trees, plants, birds, animals, fungus, etc.

Just as music is more than rhythmic sounds - it reflects the personality of its author or performer, the creek is a reflection of its author or divine creator.



Thoughts about the Artist:

When I photograph Darby Creek, I do not photograph what is there, but I photograph what should be there. The project “A Glimpse of Darby Creek: One of the Last Great Places” should not be photographed objectively, it must be subjective. It is necessary to understand what is modern man's influence on the creek's environment, and minimize that influence in the images, in order to let the true character of the creek be revealed to the viewer.

To be in-tune with the creek on an emotional and spiritual level is essential so that the imagery reflects it's divine creation.

My interest and years of observing and studying the natural world is key to my subjective analysis of photographing the Darby Creek area.
