Shoreline restoration on the Trent River

Shoreline restoration on the Trent River takes us from Hastings down through Healey Falls and Crowe Bay to Campbellford and Percy Reach. Trent Hills counts about 14 km of river along Percy and through Hastings and another 45 km through Campbellford/Seymour, with many cottages built before conservation authority flood rules. We take out failed walls, re-slope the bank on a gentle grade with mixed stone, and plant a no-mow buffer, with the permits filed for you.

Shoreline restoration

Bank washing into the lake, an old wall leaning out, ice shoving the stone around every spring? You get a shoreline rebuilt to hold, in the form the permit offices approve.

  • ✓Eroded banks re-sloped and armoured with river rock on a 3:1 slope
  • ✓Failed timber, concrete and stone walls taken out
  • ✓Native planting and a no-mow buffer that roots the bank
  • ✓Armour stone steps and seating walls up the bank to the water
  • ✓Machine and stone access planned, the site restored when we leave

The permits, handled

On the Kawartha lakes most shoreline jobs need two approvals, and the calendar matters as much as the paperwork. You sign; we prepare and file.

  • ✓Your survey checked for a City shoreline road allowance
  • ✓Pre-consultation and permit with Kawartha Conservation or Otonabee Conservation
  • ✓Parks Canada in-water and shoreline works application on Trent-Severn lakes
  • ✓The build timed to the fish-spawning window
  • ✓Every approval in hand before a machine touches the bank

We run our own excavators and skid steers, so the grading, the stone and the planting are one crew's work, with an owner on site every day.

We design to what the conservation authority and Parks Canada approve. If what you picture is a vertical armour stone wall at the waterline, you hear at the first visit what gets permitted instead, before you spend a dollar on drawings.

Shorelines on the Trent River: what the permits allow

Who signs off

Two offices sign off on most Trent River banks. Parks Canada lists the Trent River under its jurisdiction and permits all work on, under and over the bed, shoreline stabilization included, and asks for applications several months ahead. Lower Trent Conservation regulates the river corridor under O. Reg. 41/24, notes that shoreline protection can need permits from more than one agency, and has 90 days to decide a complete application. Under Bill 97, Lower Trent, Otonabee and Kawartha merge into the Eastern Lake Ontario Regional Conservation Authority on February 1, 2027. We prepare and file each application.

What gets approved

Lower Trent Conservation describes Paleozoic bedrock outcropping in the Trent River valley, and Trent Hills maps Lake Iroquois beach sands and the Campbellford and Dartford eskers across the municipality. Fifteen Trent-Severn dams between Rice Lake and the Bay of Quinte hold the river for navigation, and LTC notes that frazil ice adds flood risk beyond the spring freshet. On April 15, 2026, Parks Canada reported the Upper and Lower Trent above full and rising on inflows that included the Otonabee and Crowe rivers, and it warns that wind-driven ice can push onshore and damage shorelines.

The calendar

Because Parks Canada holds the bed, its in-water and shoreline policies set the build. Native vegetation comes first, bio-engineering second, rip-rap third. Rip-rap is clean, imported angular stone 10 to 45 cm over geotextile fabric, at a 3:1 slope and no steeper than 2:1 without a geotechnical report. The slope is cut upland rather than dug from the bed, and no stone comes out of the river. Rip-rap can reach 1 m onto the bed to protect shrubs, or 1.5 m for trees.

Shoreline restoration on the Trent River: your questions answered

Do I need a Parks Canada permit to fix my shoreline in Campbellford?

Yes. The Trent River is on Parks Canada's list of waterbodies under its jurisdiction, and all work on, under and over the bed, shoreline stabilization included, takes its permit. Permits run one year, work can be paused for fish spawning, and a Lower Trent Conservation permit can apply as well. We prepare and file both.

Can I pull the cattails and weeds in front of my Trent River property?

Parks Canada allows removal of submerged aquatic plants only after an application and review, and it does not permit removing emergent plants such as cattail, bulrush, pickerel weed and pond lily. Our work stays on the bank: a re-sloped face, stone at the toe and native planting above it.

Is my Trent River cottage in the floodplain?

Lower Trent Conservation updated its Trent River floodplain mapping from the Bay of Quinte to Hastings in 2023 and 2024, using the 100-year flood as the regulatory event, and the Trent Hills Official Plan allows no further shoreline residential development in that floodplain. We check your lot against the mapping before we draw the plan.

Do I need a permit to fix my shoreline?

On the Kawartha lakes, almost always two. Parks Canada permits all work on the bed and waters of the Trent-Severn lakes, including shoreline stabilization, and the conservation authority permits work in its regulated area along the shore. We prepare and file both.

Can I put an armour stone wall at the water's edge?

Kawartha Conservation's published guidance steers away from hardened shorelines, meaning retaining walls, sheet piles and armour stone at the water's edge. What it recommends is river rock in mixed sizes on a 3:1 slope along the natural contour, native plants and a no-mow buffer. We design to that, and put armour stone where it earns its place: steps, seating walls and terraces up the bank.

When can the work happen?

On lakes that hold walleye and bass, which is most of the Kawarthas, Fisheries and Oceans Canada's timing window keeps in-water work off-limits from March 15 to July 15 while fish spawn. Parks Canada permits are valid for one year, so we file in fall or winter and schedule the build for the open window.

How long do the permits take?

Kawartha Conservation publishes its timelines: a streamlined permit is checked for completeness in 10 days and issued within 14 more, a standard minor permit in 14 plus 21 days. Parks Canada asks for applications several months before the start date. That is why fall is the time to start.

Can you take out an old wall?

Yes. Removing a failed timber, concrete or stone wall is shoreline work too, so it goes through the same permits, and the bank is re-sloped and planted where the wall stood.

How is a shoreline priced?

By the length of frontage, the slope, how machines and stone get to the water, and what the permits require. You get a written price after the site visit, with the permit work priced in the same quote.
