The most efficient management is pollution-prevention of existing resources. However, restoration and remediation are essential tools to reverse past damage and to mitigate the impact from new impacts. This category includes stream stabilization projects, wetland creation projects, stormwater retrofits, and other approaches to provide tangible water quality improvements.  

Eroding banks can be a significant source of pollution to the lake.  Stabilizing banks with stone is an effective way to reduce erosion and protect water quality in our watershed.  We have partnered with multiple municipalities on bank stabilization projects along streams and roadside ditches.​

Sucker Brook Wetland Restoration

Sucker Brook Restoration

Sucker Brook has had flooding and water quality issues in the past. Two restoration projects were built recently in this subwatershed to increase flood resiliency and improve water quality.  Both projects bring water from Sucker Brook during storm events into a water quality area, where it can be naturally filtered before it is slowly released back to the stream.

Project Partners: NYS Department of State, City of Canandaigua, Town of Canandaigua

Route 5 & 20 Project

Project Partners: Department of State, City of Canandaigua, Town of Canadaigua

A portion of high flows from Sucker Brook will flow into an existing wetland and a newly created wetland.

County Road 30 Project

Project Partners: Department of State, City of Canandaigua, Town of Canadaigua

A portion of high flows from Sucker Brook will flow into a large temporary storage area.

Sucker Brook Headwaters Project

Restored stream with newly planted riparian trees

Project Partners: Department of State, Town of Canadaigua, Morrell Development

A tributary to Sucker Brook had an artificial sharp turn that was prone to erosion.  The stream was restored with a more natural meander and trees were planted in the riparian area.  A conservation easement now protects 7.1 acres of stream buffer and 6.7 acres of wetland.

Naples Creek Floodplain Restoration Project: Overview

Project Partners: NYS Department of State, Town of Naples, Town of Canandaigua, the Nature Conservancy, Ontario County FLLOWPA, Ontario County WRC, Canandaigua Lake Watershed Association

Naples Creek is prone to flooding, especially in the Parish Flats Road and Route 245 area.  A long history of berming has cut off Naples Creek from its floodplain. This area is especially important, because 25% of all flow the enters Canandaigua Lake passes by this project area. 


A series of projects were constructed to reconnect Naples Creek to its floodplain in strategic locations for water quality and flood resiliency benefits. Naples Creek now has more frequent and greater access to 100s of acres of additional floodplain that provides major water quality treatment. This project covers a wide geographic area (see map to the right) and included:

  • 13+ new berm breaks to allow flow to enter floodplain

  • 7 new culvert systems to convey flow into water quality storage areas

  • 110 acres of land permanently protected- including 6,300 feet of riparian corridor

  • 4 debris jams removed from the stream and bridge areas

  • Fixed trail system along stream and allowed flow to access adjacent forested floodplain system

Berm Breaks on Naples Creek and a Tributary

Multiple berm breaks were constructed along Naples Creek and one of its tributaries.  Floodwaters can now slowly filter through open lands for water quality and flood resiliency benefits.

Before project: March 18,2018 flood event - TNC land (looking south) is dry


After berm breaks were installed: August 2021 flood event - TNC land (looking north) is covered in floodwaters 


After project: multiple berm breaks were installed to allow water to reach this DEC land.

Cross Culverts for Hydrologic Reconnection

Roads often act like berms, trapping water during storm events and routing it to undesired locations. Additional cross culverts were installed under Route 245 and Parish Flats Road to allow flood waters to travel under the road and into open areas. During storms, these waters will slowly move through the land, helping to filter out pollutants and increase flood resiliency.

New cross culverts under Route 245 to carry high flows under the road and into an open area for filtering.

Stream and Road Bank Stabilization

Eroding streams and road banks can be a significant source of sediment pollution to Canandaigua Lake.  The Watershed Council has partnered with multiple municipalities and NYS Department of State to stabilize stream and road banks. Recent project photos are shown below.

Cottage City Drive Bank Stabilization

Project Partners: Department of State, Town of Gorham

A highly eroding bank was stabilized with large rocks.





Sucker Brook Streambank Stabilization

Project Partners: NYS Department of State, City of Canandaigua

A highly eroded streambank was stabilized.





Gannett Hill Road Ditch Stabilization

Project Partners: NYS Department of State, Town of South Bristol

An eroding road ditch along a steep slope was stabilized with rock rip rap.





Eelpot Creek/Garlinghouse Road Stabilization

Project Partners: NYS Department of State, Town of Naples

The road/stream bank was stabilized with stacked rock.

Sunnyside Road Drainage Improvement Project

Project Partners: NYS Department of State, Town of Italy

Improvements to catch basins and the road, along with installation of debris catches, help prevent downstream problems.




After - example of improved catch basin & debris catch

Dinehart Cross Culvert Replacement

Project Partners: NYS Department of State, Town of Middlesex

Replaced culvert, which was failing, to ensure Vine Valley Creek can continue to flow under Dinehart Cross Road and stabilized bank.

South Lake Road Rehabilitation

Project Partners: Department of State, Town of Middlesex

South Lake Road is prone to flooding and erosion problems. To increase flood resiliency, multiple undersized cross culverts were replaced and drainage improvements were constructed.  In addition, a slope failure along the road was repaired using soil nails.  

Before: Debris deposited due to undersized culvert
