Tennessee–Tombigbee Waterway
The Tennessee–Tombigbee Waterway (popularly known as the Tenn-Tom) is a 234-mile (377-kilometer) man-made waterway that extends from the Tennessee River to the junction of the Black Warrior-Tombigbee River system near Demopolis, Alabama, United States.
 The Tennessee–Tombigbee Waterway links commercial navigation from the nation’s midsection to the Gulf of Mexico.
 The major features of the waterway are 10 locks and dams, a 175 ft deep cut between the Tombigbee River watershed and the Tennessee River watershed, and 234 mi of navigation channels.
Conewago Canal
The Conewago Canal, on the west bank of the Susquehanna River below York Haven, Pennsylvania, 11 mi south of Harrisburg in York County, enabled late 18th and early 19th century rivercraft to safely bypass rapids at Conewago Falls.
 Work on the canal of less than 1 mi began in 1793 and was completed in 1797.
 Robert Morris, a Philadelphia financier, organized the project, which was carried out by chief engineer James Brindley, the nephew of a well-known British engineer of the same name.
 Two lift locks overcame 19 ft of elevation between the ends of the canal, and a guard lock blocked unwanted water, particularly during floods.
 Cargo could go upstream as well as down.
 A boat going upriver could navigate the canal in 37 minutes compared to the whole day it would take 30 or 40 men to pull it upriver along the bank.
 York Haven is at .
Okeechobee Waterway
The Okeechobee Waterway or Okeechobee Canal is a relatively shallow man-made waterway in the United States, stretching across Florida from Fort Myers on the west coast to Stuart on Florida's east coast.
 The waterway can support tows such as barges or private vessels up to 50 ft wide x 250 ft long which draw less than 10 ft , as parts of the system, especially the locks may have low water depths of just ten feet.
 The system of channels runs through Lake Okeechobee and consists of the Caloosahatchee River to the west of the lake and the St. Lucie Canal (C-44) east of the lake.
Loan modification in the United States
Loan modification is the systematic alteration of mortgage loan agreements that help those having problems making the payments by reducing interest rates, monthly payments or principal balances.
 Lending institutions could make one or more of these changes to relieve financial pressure on borrowers to prevent the condition of foreclosure.
 Loan modifications have been practiced in the United States since The 2008 Crash Of The Housing Market from Washington Mutual, Chase Home Finance, Chase, JP Morgan & Chase, other contributors like MER's.
 Crimes of Mortgage ad Real Estate Staff had long assisted nd finally the squeaky will could not continue as their deviant practices broke the state and crashed.
 Modification owners either ordered by The United States Department of Housing, The United States IRS or President Obamas letters from Note Holders came to those various departments asking for the Democratic process to help them keep their homes and protection them from explosion.
 Thus the birth of Modifications.
 It is yet to date for clarity how theses enforcements came into existence and except b whom, but t is certain that note holders form the Midwest reached out in the Democratic Process for assistance.
 FBI Mortgage Fraud Department came into existence.
 Modifications HMAP HARP were also birthed to help note holders get Justice through reduced mortgage by making terms legal.
 Modification of mortgage terms was introduced by IRS staff addressing the crisis called the HAMP TEAMS that went across the United States desiring the new products to assist homeowners that were victims of predatory lending practices, unethical staff, brokers, attorneys and lenders that contributed to the crash.
 Modification were a fix to the crash as litigation has ensued as the lenders reorganized and renamed the lending institutions and government agencies are to closely monitor them.
 Prior to modifications loan holders that experiences crisis would use Loan assumptions and Loan transfers to keep the note in the 1930s.
 During the Great Depression, loan transfers, loan assumption, and loan bail out programs took place at the state level in an effort to reduce levels of loan foreclosures while the Federal Bureau of Investigation, Federal Trade Commission, Comptroller, the United States Government and State Government responded to lending institution violations of law in these arenas by setting public court records that are legal precedence of such illegal actions.
 The legal precedents and reporting agencies were created to address the violations of laws to consumers while the Modifications were created to assist the consumers that are victims of predatory lending practices.
 During the so-called "Great Recession" of the early 21st century, loan modification became a matter of national policy, with various actions taken to alter mortgage loan terms to prevent further economic destabilization.
 Due to absorbent personal profits nothing has been done to educate Homeowners or Creditors that this money from equity, escrow is truly theirs the Loan Note Holder and it is their monetary rights as the real prize and reason for the Housing Crash was the profit n obtaining the mortgage holders Escrow.
 The Escrow and Equity that is accursed form the Note Holders payments various staff through the United States claimed as recorded and cashed by all staff in real-estate from local residential Tax Assessing Staff, Real Estate Staff, Ordinance Staff, Police Staff, Brokers, attorneys, lending institutional staff but typically Attorneys who are also typically the owners or Rental properties that are trained through Bankruptcies'.
 that collect the Escrow that is rightfully the Homeowners but because most Homeowners are unaware of what money is due them and how they can loose their escrow.
 Most Creditors are unaware that as the note holder that the Note Holder are due a annual or semi annual equity check and again bank or other lending and or legal intuitions staff claim this monies instead.
 This money Note Holders were unaware of is the prize of real estate and the cause of the Real Estate Crash of 2008 where Lending Institutions provided mortgages to people years prior they know they would eventually loose with Loan holders purchasing Balloon Mortgages lending product that is designed to make fast money off the note holder whom is always typically unaware of their escrow, equity and that are further victimized by conferences and books on HOW TO MAKE MONEY IN REAL STATE - when in fact the money is the Note Holder.
 The key of the crash was not the House, but the loan product used and the interest and money that was accrued form the note holders that staff too immorally.
 The immoral and illegal actions of predatory lending station and their staff began with the inception of balloon mortgages although illegal activity has always existed in the arena, yet the crash created "Watch Dog" like HAMP TEAM, IRS, COMPTROLLER< Federal Trade Commission Consumer Protection Bureau, FBI, CIA, Local Police Department, ICE ( The FBI online Computer crime division receives and investigates computer crimes that record keeping staff from title companies, lending institutional staff, legal staff and others created fraudulent documents to change payments and billing of note holders to obtain the money note holders are typically unaware of) and other watch dog agencies came into existence to examine if houses were purchased through a processed check at Government Debited office as many obtained free homes illegally.
 Many were incarcerated for such illegal actions.
 Modifications fixed the Notes to proper lower interest, escrow, tax fees that staff typically raised for no reason.
 Many people from various arenas involved in reals estate have been incarcerated for these actions as well as other illegal actions like charging for a modification.
 Additionally Modifications were also made to address the falsifications such as inappropriate mortgage charges, filing of fraudulently deeds, reporting of and at times filing of fraudulent mortgages that were already paid off that were fraudulently continued by lenders staff and attorneys or brokers or anyone in the Real Estate Chain through the issues of real estate terms to continue to violate United States Laws, contract law and legal precedence where collusion was often done again to defraud and steal from the Note Holder was such a common practice that was evidence as to why the Mortgage Crash in 2008 occurred for the purpose of wining the prize of stealing form Homeowners and those that foreclosed was actually often purposefully for these monies note holders were unaware of to be obtained which was why Balloon mortgages and loans were given to the staff in the Real Estate Market with the hoper and the expectation that the loan holders would default as it offered opportunity to commit illegal transactions of obtaining the homeowners funds.
 While such scams were addressed through modifications in 2008.
 The Market relied heavily on Consumers ignorance to prosper, ignorance of real estate terms, ignorance on what they were to be charged properly for unethical financial gain and while staff in real estates lending arenas mingled terms to deceive y deliberate confusion consumers out of cash and homes while the USA Government provided Justice through President Obamas Inception and IRS Inception of Modifications which addressed these unethical profits in Reals Estate.
 It was in 2009 that HARP, HAMP and Modifications were introduced to stop the victimization of Note Holders.
 Taking on the Banks that ran USA Government was a great and dangerous undertaking that made America Great Again as Justice for Consumers reigned.
 Legal action taken against institutions that have such business practices can be viewed in State Code of Law and Federal Law on precedent cases that are available to the public.
 Finally, It had been unlawful to be charged by an attorney to modify as well as fro banking staff to modify terms to increase a mortgage and or change lending product to a balloon in an concerted effort to make homeowner foreclose which is also illegal, computer fraud and not the governments intended purpose or definition of a modification.
Holcut, Mississippi
Holcut was a small town located in Tishomingo County, Mississippi, United States.
 In 1976, the U.S. Army Corps of Engineers bought out and then completely demolished the town because it lay directly in the path of the Divide Cut, a 29 mi artificial canal section of the Tennessee–Tombigbee Waterway, which was constructed between 1972 and 1984.
Tombigbee River
The Tombigbee River is a tributary of the Mobile River, approximately 200 mi (325 km) long, in the U.S. states of Mississippi and Alabama.
 Together with the Alabama, it merges to form the short Mobile River before the latter empties into Mobile Bay on the Gulf of Mexico.
 The Tombigbee watershed encompasses much of the rural coastal plain of western Alabama and northeastern Mississippi, flowing generally southward.
 The river provides one of the principal routes of commercial navigation in the southern United States, as it is navigable along much of its length through locks and connected in its upper reaches to the Tennessee River via the Tennessee-Tombigbee Waterway.
Gaines Trace
The Gaines Trace was a road in the Mississippi Territory.
 It was constructed in 1811 and 1812 from the Tennessee River (opposite the Elk River's mouth) to Cotton Gin Port on the upper Tombigbee River and on to Fort Stoddert on the lower Tombigbee.
 The portion from the Tennessee River to Cotton Gin Port was surveyed in 1807 and 1808 by Edmund P. Gaines, the road's namesake.
Conoy Canal Trail
The Conoy Canal Trail is a section of the planned Northwest Lancaster County River Trail, that runs for 3.75 miles along the Conewago Canal which stretches from Bainbridge to Falmouth.
 The canal was opened in 1797.
 As a trail, it has been opened to hikers, bikers, fisherman, and runners for more than a decade.
Eider Canal
The Eider Canal (also called the Schleswig-Holstein Canal) was an artificial waterway in southern Denmark (later northern Germany) which connected the North Sea with the Baltic Sea by way of the rivers Eider and Levensau.
 Constructed between 1777 and 1784, the Eider Canal was built to create a path for ships entering and exiting the Baltic that was shorter and less storm-prone than navigating around the Jutland peninsula.
 In the 1880s the canal was replaced by the enlarged Kiel Canal, which includes some of the Eider Canal's watercourse.
Indian Creek (Miami Beach)
Indian Creek is a partly natural and partly man-made waterway in the city of Miami Beach, Florida, United States.
 It starts as a man-made canal where Biscayne Bay meets Lincoln Road, and runs along Dade Boulevard, forming the boundary between South Beach and the rest of the city.
 At 24th street the canal opens into the natural waterway and continues north through the city past Allison Island where it opens into Biscayne Bay, till 71st Street where it merges with Normandy and Tatum Waterways and is no longer called Indian Creek.

Question: Did man-made modifications to Conewago Canal and Tennessee–Tombigbee Waterway assist in navigating these passages?
Answer: yes
