2.0 DAM SAFETY PERMIT APPLICATION RED MILL POND DAM, MONTVILLE PARTIAL REMOVAL OF RED MILL POND DAM [DEEP #08610]
Page 7a of 13 – 2.0 Dam Safety Permit Application
PART V.6
Items shown with “See attached” on Page 7 of 13 are noted as such because the current
dam configuration consists of an earth embankment dam with a primary spillway at the left side
at an elevation of 183.6 ft. and an auxiliary spillway directly adjacent to it at an elevation of
184.0 ft. Though we are proposing a partial breach, these two spillways are to be left in place.
6.a – The height of the remaining embankment adjacent to the breach, on both left and right, will
remain the same, as well as the elevations of the two remaining spillways, both of which are
broad crested weirs. The new breach opening will be a trapezoidal opening shape with a riprap
base having the characteristics noted on the plan details.
6.b – As noted above, the trapezoidal shape characteristics are detailed on the plans. The base
will be level with 2H:1V side slopes.
6.c – The base lengths of the two existing spillways are 58.6 ft. and 53.2 ft, respectively for the
primary and auxiliary spillways. The new breach opening at the base of the trapezoidal shape
will be 67.85 ft.
6.d – The spillway heights above stream bed are 6.6 ft. and 9.0 ft. respectively for the primary
and auxiliary spillways, The new breach opening situated at the right side of the dam, will slope
to the existing stream bed at a 6H:1V grade, a drop of 8.0 ft.
6.e – The freeboard for the current spillways at the 100-year storm event is 1.6 ft. The freeboard
for the partial breach during the 100-year event will be 5.1 ft. The 100-year event with the new
breach opening, at an elevation of 183.4 ft., will be 0.2 ft. below the existing primary spillway
crest. Note that this does not take into account the current sluice gate opening, which will be left
in an open position.
6.f – The water surface elevation will change from 183.6 ft. to 180.0 ft. once the breach is
constructed, a reduction of 3.6 ft. The remaining pond area will be 1.25 ac.

EXECUTIVE SUMMARY
ATTACHMENT B - EXECUTIVE SUMMARY PERMIT APPLICATION – RED MILL POND DAM PARTIAL REMOVAL OF RED MILL POND DAM [DEEP #08610]
Executive Summary - 1
EXECUTIVE SUMMARY Red Mill Pond Dam is located on Oxoboxo Brook in the Palmerstown section of the Town of Montville, southwest of Route 163 (Oakdale Road) and northeast of Maple Avenue. The impoundment behind the dam has no recent, current, or prospective use. The reservoir is impounded by an earth embankment dam situated on its southeast side. Its water surface elevation has been maintained in the recent past by the primary spillway, situated at the left side dam abutment. This spillway represents the historic water surface at the site. An additional auxiliary spillway, directly adjacent to right side of the primary spillway, was added for additional outflow capacity during the dam’s reconstruction in 1995. Discharge flow from the dam and pond continues downstream as Oxoboxo Brook, running southeasterly until it joins the Thames River. The dam, rated as a “BB” hazard structure, is currently in good condition, with maintenance performed on a routine basis. The current proposal – the subject of this permit application – seeks to permanently remove a portion of the embankment and construct a new flow channel to reduce the impoundment of flow and facilitate the passage of Oxoboxo Brook
downstream on a natural basis. Due to its lack of current or prospective use and the feasibility of
conducting a partial embankment removal without the need for removing sediment from the pond
basin, this dam is a good candidate for partial removal. Following the completion of the proposed
work, part of the impoundment area upstream of the structure is expected to return to a natural
wetland state. Although specific information on the construction of the dam was not available,
water at the site has been impounded since at least the mid-19th century, and is shown on historical
mapping as early as the 1868 Petersen Map of Montville.
The watershed for the pond encompasses approximately 9.91 square miles and the pond’s
surface area is approximately 3.3 acres in size. The watershed includes several dams and
impoundments of varying sizes and storage capacities. It is characterized by wooded rolling
terrain, sparsely developed rural housing areas, and consists of a majority of soils that are
generally well-drained to moderately well-drained. Approximately 1.5 square miles of the
watershed is located in the Town of Salem, to the northwest of the Town of Montville; the rest is
full situated in Montville. The watercourse connecting these ponds and dams is Oxoboxo Brook,
coursing its way to Red Mill Pond over a distance of 8.0 miles, while the full run to its junction
with the Thames River at Horton Cove covers about 10.4 miles.
In May of 2022, a breach analysis for the purpose of a hazard reduction was completed for
this site. There were 10 upstream dams, of which there were five major and five minor dams. The
significant upstream dams include (from the headwaters) Oxoboxo Lake, Parish Pond, Schofield
Pond, Wheeler Pond and Rockland Pond. Five dams, also included along the Oxoboxo Brook,
were smaller in size with minor impoundments and minimal storage that did not warrant inclusion
in the analysis.
The storms evaluated included the 100-year, 200-year and 500-year storm events with respect to inflow, storage and outflow at each site. Red Mill Pond Dam can withstand severe storm situations up to and including the 200-year event. For the 500-year event, it was found that the dam would be overtopped by about 0.2 ft. Because of the large size of the full watershed (9.91 square
ATTACHMENT B - EXECUTIVE SUMMARY PERMIT APPLICATION – RED MILL POND DAM PARTIAL REMOVAL OF RED MILL POND DAM [DEEP #08610]
Executive Summary - 2
miles) and the small size of the Red Mill Pond Dam impoundment (3.2 acres), an analysis between pre-breach and post breach flows, based on a 3-hour breach time, showed no increase in downstream water levels due to the breach. Based on these findings, a hazard reduction was granted by Dam Safety from a “B” to “BB” in August of 2022. As part of the proposed work, a staging and storage area will be required during construction, outside of the bounds of the proposed breach area. Sufficient area for this purpose exists outside wetland areas (denoted on the plans) adjacent to the west / right side of the dam. All excavated material, after drying out, will be taken off site. Environmental controls have been included in this proposal and additional safety measures will be instituted once construction on this project commences. Submittals will include a water
control plan, as well as an emergency plan, to be provided prior to the start of construction. It is
anticipated that the water level in the reservoir will be lowered for ease of construction, and
subsequently left at that level following completion of work.

FLOOD CONTINGENCY PLAN
Prior to undertaking the construction of the dam breach, the Contractor is required to
submit a flood contingency or emergency plan, as well as a water control plan. This will be
reviewed and approved by the Engineer, who will work with the Contractor during construction
to avoid any potential hazards.
Weather conditions will be monitored on a continual basis while work is undertaken and
if any predictions of serious conditions are anticipated, construction equipment will be removed
from any flood hazard area and work will be protected and / or reinforced to avoid any serious
environmental problems. Sedimentation and erosion controls are required to be in place prior to
the commencement of construction and will be inspected on a continuous basis until such time as
slopes and other susceptible areas have been fully stabilized.
Attached is a sample form for emergency plans for water related construction projects for
the type such as that being submitted for the current application. Unless the Contractor has a
suitable form addressing items noted herein, this form will be used to prepare for the event of a
significant storm event during the work under this permit application.

4. Emergency Situations / Duties to be Performed3: (A) Heavy Precipitation / High Winds / Potential Flooding:
Subsequent to predictions of heavy rains and / or associated wind storms, and
prior to high flows, the Contractor will monitor weather conditions and place a responsible individual and associated crew on notice to be available to remove equipment from flood plain and / or other flood prone areas to high ground that will not be affected by flooding and to tie down or store loose equipment that
could become air-borne during high wind situations. Note that the responsible
individual and associated crew will also be available during the storm to monitor conditions and perform any duties related to maintaining the safety of the site. This may include use of equipment to deter flooding of the direct construction site and to divert flow away from erodible or collapsible work areas.
(B) Material Storage and Flooding: Weather conditions and forecasts will be monitored on a continual basis while work is undertaken and if any predictions of serious conditions are anticipated,
mechanical construction equipment, loose or unstabilized storage piles of earth
materials, tools, concrete forms and any other work related materials or storage containers will be removed from any flood hazard area and work will be protected and / or reinforced to avoid any serious environmental problems. Sedimentation and erosion controls, required to be in place prior to the commencement of
construction, will be inspected on a continuous basis until such time as flooding
abates or is no longer a threat to the work site. (C) Stability of Existing or New Facilities:
Where necessary and predictable, existing or new facilities must be stabilized
prior to a storm event, to the extent possible and safely workable without endangering Contractor’s personnel or the public. This may include bracing or buttressing of walls, placement of barriers around new soil slopes, placement of diversionary cofferdams, etc. to avoid damage or loss of facilities under
construction.
(D) Fire: Basic firefighting equipment, such as extinguishers, shall be maintained on site at
or near equipment. The first responsibility in the event of a fire will be to contact
emergency services through 911 and then attempt to extinguish the blaze with equipment on hand relative to the severity of the situation without putting personnel into danger prior to arrival of emergency services.
3 These items are intended as guidelines, not directives to the Contractor. They may be used and / or modified by the
Contractor in setting up an individual plan.

PARTIAL REMOVAL OF RED MILL POND DAM [DEEP #08610]
Alternatives Assessment - 1
ALTERNATIVES ASSESSMENT
Red Mill Pond Dam is an existing structure. Based on its current condition, alternative
courses of action at the site would include doing nothing or breaching and / or removing either
the entire dam or a portion thereof.
In its existing condition, continued maintenance could ensure that the dam remains in
good condition and continues to function properly, including during storm events. However, the
dam has no current, recent, or prospective future use. As such, its full or partial removal presents
a logical and feasible alternative to doing nothing. A partial removal has been deemed the most
practical alternative as it can be accomplished without the removal of sediment from the base of
the impoundment and will leave a portion of the impoundment remaining in place while
beginning to return the impoundment to a natural, wetland environment and restoring the
upstream portion of the natural channel of Oxoboxo Brook.
A secondary benefit to a partial removal of the dam will be realized in the form of a
reduced hazard to downstream areas in the event of a potential breach caused by overtopping and
/ or a collapse of portion of the structure during a high flow storm event.
It should also be noted that the absence of a spillway or other large stone or concrete
elements in the section of this dam proposed for removal will facilitate an efficient completion of
the partial removal proposed in this application.

Recommendation for Red Mill Pond Dam (#08610)
While a fishway at Red Mill Pond Dam is desirable, it is not currently necessary at this time.
Oxoboxo Brook has been identified as a target for anadromous fish restoration. Alewife,
Blueback Herring, Sea Lamprey, and American Eel once utilized the brook as spawning and
rearing habitat. American Eel continues to be present upstream and downstream of the dam,
and the current engineered plans to lower the pond will allow safe, timely, and effective
passage for American Eel.
Although no formal plans exist at this time, discussions are ongoing regarding improvements to
fish passage along Oxoboxo Brook, from its confluence with the Thames River upstream beyond
Red Mill Pond. Once anadromous fish can migrate past the two downstream dams, Red Mill
Pond Dam will become the first barrier preventing further upstream migration. At that point,
implementing fish passage at this dam will be necessary to support the restoration efforts for
anadromous species in Oxoboxo Brook.

The proposed work at Red Mill Pond Dam will be limited to areas already existing as
parts of the dam or its structural appurtenances. The major part of the work will consist of a
partial breach of the dam, via removal of a portion of the right side earth embankment, such as to
reduce the water level within the pond. Flow will continue from this site, after breaching, via a
new channel created by the lowering of a section of the embankment discharging into Oxoboxo
Brook, thence continuing downstream to its outlet at the Thames River. There is some clearing
of brush proposed along adjacent areas, but the majority of the existing embankment will be left
in a natural state.
The overall environmental impact of the proposed work is expected to be positive, as it
will stabilize the long-term condition of the site, preserve the flow regime of Oxoboxo Brook,
and return the site to a more natural, less maintenance-intensive state which presents a lower
potential hazard to downstream areas in the event of a dam failure.
Finally, it is important to point out that this site – including both the dam and the pond –
is not located either within or near an NDDB resource area.
