Watson's Mill - Manotick

Watson's Mill is an historic flour and gristmill in Manotick, Ontario, Canada. It is the only working museum in the Ottawa area and one of the very few operating industrial grist mills in North America. Watson's Mill still sells stone-ground whole wheat flour which is made on site. The mill is also well known for its ghost story. The legend is that Ann Currier, wife of Joseph, haunts the mill, following her death in a tragic accident there in 1861. Watson's Mill is Manotick's most recognized landmark. Its image is used as a symbol for the village.

Gristmill mill; grinds grain into flour

A gristmill grinds cereal grain into flour and middlings. The term can refer to both the grinding mechanism and the building that holds it.

Ontario Province of Canada

Ontario is one of the 13 provinces and territories of Canada. Located in Central Canada, it is Canada's most populous province accounting for 38.3 percent of the country's population, and is the second-largest province in total area. Ontario is fourth-largest jurisdiction in total area when the territories of the Northwest Territories and Nunavut are included. It is home to the nation's capital city, Ottawa, and the nation's most populous city, Toronto, which is also Ontario's provincial capital.

Ghost Soul or spirit of a dead person or animal that can appear to the living (for ghosts from a work of fiction see Q30061299)

In folklore, a ghost is the soul or spirit of a dead person or animal that can appear to the living. In ghostlore, descriptions of ghosts vary widely from an invisible presence to translucent or barely visible wispy shapes, to realistic, lifelike forms. The deliberate attempt to contact the spirit of a deceased person is known as necromancy, or in spiritism as a séance.


Moss Kent Dickinson and Joseph Merrill Currier founded the mill as the Long Island Milling Enterprise in 1860. It was one of a series of mills constructed in the area using power from the Rideau Canal. It earned its current name when it was purchased by Harry Watson in 1946. Watson was the last owner to operate the mill at an industrial level. When the Rideau Valley Conservation Authority bought the mill in 1972, it was developed into a museum.

Moss Kent Dickinson Canadian politician

Moss Kent Dickinson was a Canadian businessman, mayor of Ottawa from 1864 to 1866, Member of Parliament from 1882 to 1887 and the founder of Manotick.

Joseph Merrill Currier Canadian politician

Joseph Merrill Currier was a Canadian member of parliament and businessman.

Rideau Canal Canal in Canada

The Rideau Canal, also known unofficially as the Rideau Waterway, connects Canada's capital city of Ottawa, Ontario, to Lake Ontario and the Saint Lawrence River at Kingston, Ontario. It is 202 kilometres in length. The name Rideau, French for "curtain", is derived from the curtain-like appearance of the Rideau River's twin waterfalls where they join the Ottawa River. The canal system uses sections of two rivers, the Rideau and the Cataraqui, as well as several lakes. The Rideau Canal is operated by Parks Canada.

The mill is open to the public during the summer months and hosts a variety of events, including milling demonstrations every Sunday.


Watson's Mill was originally known as the 'Long Island Milling Enterprise', and was constructed by Thomas Langrell, an Ottawa contractor, for two prominent Ottawa businessmen: Moss Kent Dickinson and Joseph Merrill Currier. Dickinson was a successful forwarder and steamboat owner. He was nicknamed 'King of the Rideau' because of his many freight and passenger steamers that travelled up and down the Canal. Dickinson was also mayor of Ottawa from 1864 to 1866, just prior to Confederation, and lived in what is now the South African Embassy. His partner, Joseph Currier, was a lumber baron, and a partner in the Victoria Foundry located in Ottawa, where all of the Mill machinery was cast. Watson's Mill was originally one of four milling operations built at the same time. A saw mill was completed in 1859, the gristmill in 1860, and a carding mill in 1861. The Canada Bung, Plug and Spile Factory was constructed in 1875, completing the Long Island Milling Enterprise, later to be known as the 'Manotick Mills'.


A forwarder is a forestry vehicle that carries big felled logs from the stump to a roadside landing. Unlike a skidder, a forwarder carries logs clear of the ground, which can reduce soil impacts but tends to limit the size of the logs it can move. Forwarders are typically employed together with harvesters in cut-to-length logging operations.

Steamboat Smaller than a steamship; boat in which the primary method of marine propulsion is steam power

A steamboat is a boat that is propelled primarily by steam power, typically driving propellers or paddlewheels. Steamboats sometimes use the prefix designation SS, S.S. or S/S or PS ; however, these designations are most often used for steamships.

Ottawa Federal capital city in Ontario, Canada

Ottawa is the capital city of Canada. It stands on the south bank of the Ottawa River in the eastern portion of southern Ontario. Ottawa borders Gatineau, Quebec; the two form the core of the Ottawa–Gatineau census metropolitan area (CMA) and the National Capital Region (NCR). As of 2016, Ottawa had a city population of 934,243 and a metropolitan population of 1,323,783 making it the fourth-largest city and the fifth-largest CMA in Canada. In June 2019, the City of Ottawa estimated it had surpassed a population of 1 million.

Dickinson intended to develop a village around the Long Island Mills complex. He bought 30 acres of land and sold it as building plots. The village was named 'Manotick', an Algonquin word meaning island. Dickinson also built a house across from Watson's Mill, which still stands today and has been turned into the 'Dickinson House Museum'.

Algonquin is either a distinct Algonquian language closely related to the Ojibwe language or a particularly divergent Ojibwe dialect. It is spoken, alongside French and to some extent English, by the Algonquin First Nations of Quebec and Ontario. As of 2006, there were 2,680 Algonquin speakers, less than 10% of whom were monolingual. Algonquin is the language for which the entire Algonquian language subgroup is named. The similarity among the names often causes considerable confusion. Like many Native American languages, it is strongly verb-based, with most meaning being incorporated into verbs instead of using separate words for prepositions, tense, etc.

Watson's Mill remained in the Dickinson family until 1928 when Elizabeth, Moss Kent Dickinson's youngest daughter, sold it to Alexander Spratt. Spratt had six children: Charlie, Billie, Helen, Ken, Dick and Hubert. The whole family lived in the Dickinson House while Alexander was running the mill. Alexander died of brain cancer in 1936. His wife continued with the business until it was sold in 1946 to Harry Watson. Watson, his wife Anna and his six children Ron, Bill, Jack, Jim, Bob and Mary all lived in the Dickinson House as well.

With the introduction of the Canadian Pacific Railway, it became cheaper to import wheat and flour from the West than to grow and mill wheat in Ontario. Spratt and Watson gradually transformed the Mill into a feed and seed operation to keep up with the changing times and to accommodate the local dairy and livestock farmers. Watson also began distributing coal and cement.

Canadian Pacific Railway Major class 1 railroad operating in Canada and the U.S.

The Canadian Pacific Railway (CPR), also known formerly as CP Rail between 1968 and 1996, and known as simply Canadian Pacific is a historic Canadian Class I railroad incorporated in 1881. The railroad is owned by Canadian Pacific Railway Limited, which began operations as legal owner in a corporate restructuring in 2001.

Wheat Cereal grain

Wheat is a grass widely cultivated for its seed, a cereal grain which is a worldwide staple food. The many species of wheat together make up the genus Triticum; the most widely grown is common wheat.

Flour powder which is made by grinding cereal grains

Flour is a powder made by grinding raw grains, roots, beans, nuts, or seeds. It is used to make many different foods. Cereal flour is the main ingredient of bread, which is a staple food for most cultures. Wheat flour is one of the most important ingredients in Oceanic, European, South American, North American, Middle Eastern, North Indian and North African cultures, and is the defining ingredient in their styles of breads and pastries.

Ann Crosby Currier

Watson's Mill is haunted by the ghost of Ann Crosby Currier, the second wife of Joseph Currier. Born in 1841, Ann was the daughter of a successful hotel owner and grew up along with seven siblings, in the village of Caldwell, New York. In 1861, Ann was married to Joseph Merrill Currier, at that time a co-owner of the Mill.

New York (state) American state

New York is a state in the Northeastern United States. New York was one of the original thirteen colonies that formed the United States. With an estimated 19.54 million residents in 2018, it is the fourth most populous state. In order to distinguish the state from the city with the same name, it is sometimes referred to as New York State.

On Monday, March 11, 1861, 6 weeks into the marriage, coinciding with the return from Joseph and Ann's honeymoon, Currier and Dickinson held a small party to celebrate their first successful year of operation. While making their way through the congestion of moving equipment and machinery, tragedy struck. Ann's crinoline and dress became caught in one of the turbine shafts on the second floor of the Mill and she was flung against a pillar and killed instantly. Following this tragedy, Joseph immediately lost all interest in the Mill and eventually sold his shares to his partner Dickinson.

Since that time, there have been numerous unconfirmed sightings of Ann's ghost in Watson's Mill, causing the site to be often considered among Ottawa's haunted buildings. Watson's Mill currently runs a number of events promoting the haunted nature of the building including the Terrifying Tales at Twilight and visits by the Haunted Ottawa and Paranormal Society. [1]


Watson's Mill was built using limestone quarried from the banks of the Rideau River, as well as wood cut locally and milled at the Long Island Sawmill. The mill's interior is highly ornamented; the partners, Dickinson and Currier, wished to make the Mill a model for industrial achievement and business entrepreneurship. Watson's Mill was powered by five turbines constructed in Joseph Currier's foundry. With a sixth turbine that was used to power the Bung Mill across the river. The Ottawa Citizen newspaper described Watson's Mill as "a castle in the air" on its opening day.

Watson's Mill continues to run milling demonstrations on Sundays during the summer season. Whole wheat flour milled onsite is available for sale in the gift shop as well as fresh whole wheat bread made from Watson's Mill flour. Today, Watson's Mill still has much of the original machinery in working order. The following machinery is active in milling demonstrations:


The turbines are the most important pieces of machinery as they supply power to all the other equipment in the mill. They are the originals, cast in 1859 in the Victoria Foundry in Ottawa. The larger turbines can generate 40-horse power and the smaller one makes 20-horse power. The turbines could operate all year, because the constant flow of water through the flume never froze. The first turbine drives the feed grinder and bolter, the third drives the elevators and auger, and the fifth drives the millstones and the seed cleaner. The other three are no longer in use.

Hopper, Elevators and Garner Bin

After the wheat is weighed, it is dumped into the receiving hopper. There is a small opening at the bottom, which is controlled by a lever. It allows the miller to control the amount of wheat that enters the system. This begins the automated milling process. From this point on, the grain and grist do not come into contact with human hands until the flour is ready to be bagged. Once poured through the hopper, the grain is conveyed to the second floor, via the conveyor elevator, and stored in a large storage bin called the garner bin.

Millstones and Auger

Millstones can be made from a variety of materials. The stones at Watson's Mill are made from pieces of very hard quartz called buhrstone. They were imported from France in 1859. The reason for this was that native stone from Canada and the United States would chip off into the final product. The face of the stone has a pattern of grooves, which is called the dress. Different types of millstones have different patterns - Watson's Mill's millstones have a 3/4 dress. The particular dress of the stone indicates what substance it ground. The grooves on the two stones are at different angles, and they act like scissors during milling. Only the top stone, the runner stone, turns, while the bottom bedstone remains stationary. The stones each weigh about 900 kilograms, which is about the weight of a Volkswagen Beetle.

Two large iron cast wheels in front of the millstone are used by the miller to control the machinery. The small wheel allows the miller to raise and lower the top stone, or runner. The large wheel is used to open the gate to the turbine that turns the millstone.

Since the top stone is so heavy, and spins quickly, a significant amount of heat is generated, which in turn warms the grist. It is important that the windows in the mill are open during milling, because dust particles are combustible. During the process, when the grist is warm and moist, it is difficult to separate the bran and chaff from the flour, so the grist needs to be cooled. The grist travels up to the attic in the grist elevator, where it falls into a machine called the auger, which cools and fluffs the grist.


From the auger, the grist falls into the bolter. The bolter is a large sifting machine located on the second floor. The bolter separates the flour from the bran so that pure stone-ground whole wheat flour is the final product. Both products drop down to the main floor where they are separated into two different bags. The flour is then bagged into smaller portions which can be purchased at the mill.

Feed Grinder

The feed grinder introduced another method of grinding grain. Whereas the particular dress of the millstones limits what substance can be ground, the feed grinder was capable of grinding a variety of grains and seeds. This machine was mostly used to mix feed for the local farmers' animals. Today the feed grinder is used to grind corn, which the mill sells as duck chow.

Long Island Milling Enterprise

In addition to the grist mill, a sawmill, carding mill and bung factory were also part of the Long Island Milling Enterprise.


Located on the opposite bank of the river, Moss Kent Dickinson and Joseph Currier built their first sawmill using their newly acquired waterpower rights to the dam. The sawmill was built sometime before 1859 and wood sawn from this mill was used in the construction of the Long Island Grist Mill (Watson's Mill). The sawmill was small in size, measuring only 72 feet by 22 feet. Due to the expansion of the bulkhead in 1870, this first sawmill had to be removed. Construction for a new sawmill began before the old one was torn down.

The second sawmill was larger than the first, measuring 30 feet by 100 feet. By 1876, a 20-foot addition was added to accommodate the new Canadian Bung, Plug and Spile Factory. The second sawmill was destroyed by fire over the summer of 1887. Although all physical evidence of the sawmill is now gone, it played a vital role in the creation of Manotick by providing lumber for the manufacture of woodwork for wagons, carriages, sleighs, wheels, furniture and building construction.

Carding mill

Built in just eight months, the woolen carding mill was opened December 1, 1861. Located beside the gristmill, the carding mill completed the three buildings that made up the Long Island Milling Enterprise.

Originally the carding mill measured 32 feet by 30 feet, but by 1870 more space was needed and the mill was expanded to 60 feet by 30 feet. This mill was not only a place where farmers could have their wool carded and dressed, but also where custom cloth could be ordered. From 1874 to 1876, the carding mill was leased to R.W. Conway who ran the business. The carding mill met its fate when a fire destroyed the entire building. The exact date of the fire is not known, but it is believed to have occurred sometime between 1879 and 1885. Although useful to farming families, the carding mill was never replaced, scratched out of Dickinson's records by Moss Kent himself. Today, very little remains of the carding mill, except for remnants of its foundation buried in the riverbank.

Bung factory

Moss Kent Dickinson established the Canada Bung, Plug and Spile Factory in 1875. At the time, there was only one other operation in Canada. Dickinson shipped his bungs (wooden stoppers for barrels) all over the world

After the Sawmill, which originally housed the bung factory, burned in 1887, Dickinson decided that only the bung mill was worth salvaging. A new building was constructed a little ways downstream and on the opposite riverbank from the gristmill.

To power the bung mill, a sixth turbine was installed in the basement of his gristmill, and a 3 inch steel cable ran out of the basement window and across the river channel to the new mill. When power was needed, a string was pulled, which rang a bell in the gristmill, notifying the miller to start the sixth turbine. The bung factory was dismantled in 1926 and moved to become part of a residence on Long Island in Manotick.

Modern Times

On July 1, 1963, the National Capital Commission (NCC) entered into a lease agreement with Harry Watson to open the Mill as a heritage attraction. The Rideau Valley Conservation Authority (RVCA) purchased Watson's Mill, Dickinson House and the Carriage Shed in 1972 in order to preserve this heritage landmark and the name 'Watson's Mill' was kept. The RVCA significantly restored the Mill – reopening it as a functioning grist mill and museum. In 2008, Watson's Mill Manotick Incorporated (WMMI) became the owner of the Watson's Mill property. Today, it continues to run as a functioning industrial museum and community social centre. Watson's Mill thrives with a mandate to continue operating as a flour and feed mill, as well as a social, cultural and educational focal point for its many visitors.

Watson's Mill is situated on the banks of the Rideau River, in the village of Manotick, Ontario. It is built next to the control dam on the backchannel as the Rideau River splits around Long Island. Built across the other channel are the Long Island Locks. Watson's Mill is 20 km south of downtown Ottawa, Ontario.
