    I found the second paragraph of the discussion of Mrs. Dennett's paper particularly
    interesting. Assuming that Charles Merrill retired at the age of 65 (not necessarily true,
    but probably not far off), the water wheel or turbine would have been available for use
    up until around 1946. I wish someone was taking pictures before and while they removed
    it, but so far none have turned up. In Reggie Sweet's memories of the Westcott Mill in
    Spindleville, he mentioned that the water wheel there could still be used in his time which
    went up to the closing after the flood of 1955..

                     Mill River Remains An Important Asset To Milford, Hopedale

                   
                                               By Gordon E. Hopper

    Mill River is not a very enchanting name. It is not even a large river. In fact there are places
    where it is difficult to find it. It has a historical background and has always been important to
    the economy of the local area.

    The stream follows a southerly course from its point of origin through Hopkinton, Milford,
    Hopedale, Mendon, Blackstone and Woonsocket, RI. From there it runs to the tidewater at
    Pawtucket and Providence. The river starts somewhere under Lake Maspenock (aka North
    Pond) in Hopkinton and forms its outlet at the Milford dam. Around 1880, the height at this
    dam was determined as 452 feet and 9 inches above the Atlantic Ocean tidewater at
    Providence.

    Before the river leaves Milford it falls 136 feet and 9 inches reaching a height of 316 feet
    above tidewater. That is about 8 feet and 3 inches higher than the Charles River where it
    leaves Milford. There were eleven mill sites on the Mill River in the Milford-Hopedale area at
    that time, six of which were in use. The first three northernmost sites were not occupied and
    they lowered the river by 33 feet.

    The fourth dam where a miller named Fisk once operated a grist and sawmill had an 11 foot
    fall. There was a six foot fall at the so-called “City” which was idle. Hopedale Machine
    Company occupied the sixth privilege with a 12-foot fall, the next site being occupied by the
    Dutcher Temple Company in Hopedale, probably using a large dam, as it had a 16-foot fall.
    (The Hopedale Machine Company was one of a number of companies that were later
    organized as Draper Company, and by 1916, Draper Corporation. The dam referred to
    would be the one at Freedom Street, which forms Hopedale Pond. The dam and pond at
    the Dutcher Temple Company was a short distance downstream. By sometime in the 1890s
    it was drained as water power was no longer needed, but room for more shops for the
    expanding business was needed.)

    Samuel Walker’s grist mill with a 9-foot fall occupied the eighth site. The ninth was at
    Spindleville with a drop of 11 feet. The two remaining sites had a drop of about 13 feet.
    Another drop of 25-feet is absorbed by ponds and slack water.

    In 1667, the early Mendon authorities provided for the erection of their first corn mill on the
    Lewis B. Gaskill property where Mill River left Milford. Benjamin Albee or Alby, was engaged
    to maintain the mill for the convenience of the public on a piece of land that was granted to
    him. It is believed that he built the mill, but it, along with most all of the buildings built by
    Mendon’s first settlers, were burned during King Phillips’s War.

    In 1708, a road was laid out from the iron works in Mendon to Dedham. The iron works
    probably was a forge owned by Jonathan Richardson on the Mill River and this road
    probably is the present Bellingham Street.

    In 1753, there was a gristmill located on the Mill River in Mendon owned by a Quaker named
    James Cargill. From him it passed to Seth Kelly and was known as Kelly’s Mill. Although not
    verified it is possible that a sawmill, three or four cotton mill, and a machine shop did
    operate in Mendon on the river.

    The name of Mill River has never changed since the founding of Quinshipaug Plantation
    (Mendon or Mendham) around the year of 1633. Its many mill privileges led our early
    ancestors to give it the name it possesses, although Maspenock River would sound more
    graceful.

    The river had several usable fords that were familiar to the Indians and used for many years
    by the early white settlers before any bridges were built.

    The dams and mill privileges along the Mill River have remained and today they are still
    there although the purposes they serve has changed. From an early requirement of
    providing power for mill operations it has changed to become a means of providing various
    cooling processes in modern day industries. Water  levels of Lake Maspenock and a small
    mill pond on West Street at the Milford-Hopedale town line, and Hopedale Pond, are raised
    or lowered as the industrial needs of the Draper Division require, or as rainfall conditions
    dictate. Amounts of water storage and runoff are controlled by gates installed in the dams.

    A tour of the dams between Lake Maspenock and Freedom Street reveals that they are still
    in place, that they are still functional, and that they are being used. The dam at Lake
    Maspenock in Milford, owned and maintained by the Draper Division, is in first class
    condition. Without doubt it is the longest in the Mill River network of dams, being 400 to 500
    feet long, but not the oldest. It was there at least a hundred years ago and was rebuilt
    during 1901. There is a concrete dam and spillway section in the long rollway and the dam
    is equipped with a set of gates.

    Downstream from the source, the first dam encountered retains and controls the water of
    Fisk Mill Pond.  (where the Nipmuc Rod & Gun Club is located) There are two eight foot long
    concrete dams and spillways in an earth rollway that is several hundred feet long. However
    the height of this pond cannot be controlled except by using sandbags as there are no
    gates. Around 1730, a miller named Fisk operated a saw and grist mill at this site. These
    mills and others at this location were always called the “Fisk Mills.” As late as 1900 they
    were still owned by descendants of the founder.

    Next in the chain is a very serviceable dam on Mill Pond located at the Milford-Hopedale
    town line at West Street. (Route 140) All concrete construction, approximately 25 feet long,
    the dam section is probably eight feet in length. The height of the dam is manually
    controlled by the manipulation of gate sections, one on top of each other and held in a
    framework.

    The last dam north of the Draper Division is at the plant itself. It is a concrete dam, with
    rollway and spillway located at the southern outlet of Hopedale Pond. The approximately 30-
    40 foot long dam and spillway section utilizes a flashboard and is located under the
    Freedom Street bridge. A long rollway extends from the dam to either side of Hopedale
    Pond. The spillway extends from the dam to a nearby building of the Draper complex. Water
    is channeled under the plant and continues south as the Mill River. There is a network of
    pipes leading from the bottom of the spillway into the mill.

    As the Mill River flows south, it passes the old Westcott Mills in Spindleville where it was
    once utilized, through Mendon and Blackstone where industries long ago flourished along
    its shores, and finally it empties into the Atlantic Ocean via the tidewater at Pawtucket and
    Providence, Rhode Island.

    Near the end of July in 1938, continual torrential rains required the control of water in the
    ponds north of the Draper Division plant to prevent flooding in Hopedale and in particular,
    at the Draper plant and adjacent property. It took the vigil and efforts of 10 men to control
    the safety of the area. The gates and flashboards at Hopedale Pond, Mill Pond and Lake
    Maspenock were manipulated for several hours to keep the water level down. At one time,
    water levels reached new heights and sandbags were used as a precautionary measure at
    the West Street dam and at Lake Maspenock. The flashboards at Hopedale Pond were
    removed and the level of this pond was lowered somewhat. This was an instance where the
    dams were used as a flood control device although that is not their primary purpose. In the
    past, these dams provided waterpower to operate the machinery in the many mills which
    were located along the Mill River.

    Later, and at the present time, some of the water being retained by these dams is used by
    the Draper Division (currently about 275,000,000 gallons or more, per year from Mill River
    flowage) for personal and plant sanitation, along with foundry operations and various
    cooling processes. The flowage rights are very important to the corporation because water
    for high speed machinery cooling is a must.

    Mill River along with its dams and historical background, still remains a very important asset
    to the economy of Hopedale and other towns in this area. Milford Daily News, October
