Where is Morrison Dam Conservation Area (MDCA)?

Address: 71108 Morrison Line, Exeter, Ontario

Open seven days a week, from sunrise to sunset, unless otherwise posted

Morrison Reservoir (Morrison Lake) is a human-made reservoir created by the construction of Morrison Dam in 1959 to provide a consistent water supply to a former canning factory in the town of Exeter. We invite you to explore Morrison Dam Conservation Area (MDCA) throughout the year and experience all its natural wonders!

Recreational Trails 

Explore Morrison Dam Conservation Area’s four-kilometre (2.5 mile) of recreational trail and travel along two kilometres (1.2 miles) of wide, accessible trails with an optional excursion down an additional two kilometres (1.2 miles) of more rugged trails.


Cycling is allowed along the main trail only. 

Trail etiquette 
  • Share the trail. Keep on the right, pass on left. 
  • Be a safe cyclist. Cycle slowly, give right-of-way to hikers, use a bicycle bell to warn hikers, be cautious at curves, and wear a helmet. 

Morrison Dam Conservation Area is a great place for a picnic or family reunion. The pavilion is available on a first-come, first-served basis. If you wish to reserve the pavilion, please contact the ABCA for fees and details.

Fishing is permitted in compliance with applicable legislation. Outdoor Cards and Fishing Licences can be purchased from Service Ontario and other licence issuers. Please release any fish caught out of season. 

There is a number of native fish species in the Ausable River and in Morrison Reservoir (Morrison Lake).


Geocaching is a worldwide game of hide and seek that uses GPS (Global Positioning System) technology to help people find hidden treasures called ‘caches.’ There are two geocaches at the Morrison Dam Conservation Area east of Morrison Line (more caches can be found west of Morrison Line, along the MacNaughton-Morrison Section of the South Huron Trail). Caches are of different sized waterproof containers and are hidden in a safe spot close to trails. They often contain a logbook and simple treasures like coins or toys inside. If you find a camouflaged cache by accident, have a look and put it back in the place you found it for others to enjoy.

Visit to find and download coordinates and clues to find these ‘treasures’ at the Morrison Dam Conservation Area.

Tips to Enjoy your Visit

Be aware of the following to help you enjoy your visit. 

Poison Ivy

Poison Ivy is a common, native plant in the Ausable Bayfield Conservation Authority watershed. 
‘Leaves of three, let it be. Berries white, take flight.’ Leaves may either have smooth edges or a few coarse teeth and may appear shiny. If you come into contact with Poison Ivy wash the affected area with hot soap and water as soon as possible, launder clothes in hot water. 
Habitat: Open woods, fields and roadsides, disturbed areas.

Giant Hogweed

Giant Hogweed is an invasive, non-native plant introduced from Asia. It has large, flat-topped to slightly dome-shaped flower (similar to Queen Anne’s Lace/Wild Carrot) and seed head and a bumpy or bristly stem. It can grow up to five metres in height. Skin contact with Giant Hogweed sap may cause severe skin rashes when exposed to sunlight.

Habitat: Roadsides, streambanks, waste areas, yards

Stinging Nettle

Stinging Nettle is from between half a metre in height to three metres tall. Stems and leaves are covered with short, stinging hairs which can cause irritation and inflammation if touched with bare skin. Flowers are in clusters with separate flowers attached by short stalks along a central stem about 1-7 centimetres long.

Ticks are present in the Ausable Bayfield Conservation Authority watershed. 

  • Wear light-coloured clothing, so it’s easier to see ticks
  • Wear closed-toed shoes
  • Wear long-sleeved shirts
  • Wear long pants, tucked into your socks
  • Use insect repellent containing DEET
  • After outdoor activity put your clothes in the dryer

Check yourself and your children:

  • Behind your knees
  • On your head
  • In your belly button
  • In your groin area
  • In your underarm area
  • On the back of your body – use a mirror, or ask someone to check for you

It’s a good idea to have a shower as soon as you can to wash off any ticks.

If you discover a tick on your body remove it, place the tick in a secure container and contact your local public health unit 

Directions for removal can be found here:

Why should I visit?

Morrison Reservoir (Morrison Lake) is one of the area's only inland lakes.

Visitors enjoy canoeing, fishing, picnicking, birdwatching, hiking on the five-kilometre trail.

After the construction of Morrison Dam in 1958, the Ausable River, east of Exeter was transformed into a lake ecosystem with many recreational opportunities.

Morrison Dam Reservoir has provided recreation, nature enjoyment, habitat benefits for more than 60 years

Morrison Dam Reservoir is one of area’s only inland lakes 

More than sixty years ago (in 1958), local partners created Morrison Dam and Morrison Dam Reservoir (Morrison Lake) east of Exeter.

The dam and reservoir were created, in part, to supply water for the former canning factory in Exeter. At that time, the business was a major employer and purchaser of local crops and the canning factory needed a reliable supply of water to cool the cans.

The former Ausable River Conservation Authority built the dam “with the financial assistance of both the Town of Exeter, which also gained a supplementary water supply, and the Township of Usborne, because situating the dam on the road allowance upstream from Exeter meant the replacement of an obsolete Township bridge,” according to engineer Charlie Corbett in his article From an Engineer’s View in the booklet 40 Years of Conservation.

The conservation authority began work to build the dam and reservoir in the mid-1950s and completed the work in 1958. The dam and reservoir are named after John A. Morrison.

Today, Morrison Reservoir is one of the only inland lakes in the area. The lake isn’t used as a water supply anymore but it offers many important benefits such as habitat for aquatic and terrestrial species and recreation for residents and visitors. The water surface area of the lake, at the normal summer level, is about 25 acres. At the normal summer level, the maximum reservoir depth is about 16 feet with the average depth around six feet.

People enjoy canoeing, kayaking, fishing, and nature appreciation on Morrison Lake.

Andrew Dixon, in the booklet A Tour through 25 Years of Conservation (1971), wrote that if you like to fish, canoe, or watch birds, “then the Morrison Lake is for you and is a beauty spot worth a visit.”

The conservation authority planted trees around Morrison Lake to create wildlife habitat and Morrison Dam Conservation Area (MDCA) was born.

People enjoy walking, hiking, and other multi-use trail uses such as bicycling at the conservation area. The conservation area is also home to the administration centre and office of Ausable Bayfield Conservation Authority (ABCA). The conservation area surrounding the Reservoir maintains areas of wetland habitat for many species of plants and animals.

The trails of the conservation area join with MacNaughton-Morrison Trail to form the eight-kilometre South Huron Trail.

Today, it is hard to imagine the local landscape without Morrison Dam, Morrison Lake, and the surrounding protected conservation area. David McClure, in his 2006 Annual Report article about conservation authority history between 1956 and 1960, wrote that the creation of Morrison Dam was one of the late-1950s projects that turned vision into action. He wrote that “the environmental benefits and recreational enjoyment,” of two major projects including Morrison Dam, “are the living legacy that grew out of the roots of that vision by local conservation pioneers.”

Jones Bridge - A new pedestrian bridge constructed on South Huron Trail

A community campaign took place to raise funds to create a pedestrian bridge, downstream of Morrison Dam, to join two sections of the South Huron Trail. This bridge, called Jones Bridge, provides trail users with a safer, more scenic alternative to walking beside vehicle traffic on the roadway in order to enjoy both trail sections.

The community raised more than $300,000 towards the trail bridge project, surpassing the campaign fundraising goal, and turned the Jones Bridge dream into reality in 2018.

The bridge is called Jones Bridge as it is dedicated by Donna Jones, in loving memory of Ted Jones, who was a dedicated community volunteer, conservationist, Exeter Lions Club member and Ausable Bayfield Conservation Foundation director.

The Brian Clarke memorial stairs have been constructed thanks to a generous donation, in Brian's memory, by his family.
