Master Plan

Master Plans are documents that span several years and guide and inform enhancements to our Conservation Areas.

Stream Flow Monitoring

The Niagara Peninsula Conservation Authority monitors stream flow, rainfall and other meteorological information at locations across the watershed. The information is transmitted from each station to the NPCA’s Head Office in Welland, Ontario, in near-real time where it is monitored and analyzed. The data gives us an up to date picture of the conditions within the watershed and allows us to develop a deeper understanding of the fluxes and behaviour of the systems.

Looking for more data? The NPCA also publishes water quantity and quality data through our CUAHSI-HIS Hydroserver. The HydroServer is part of the Authority’s developing Hydrologic Information System (HIS), providing publication, discovery and access to its hydrologic data through CUAHSI web services, and includes GIS water resources data.

Water Quality

The NPCA completes monthly sampling and testing at some surface water stations and groundwater wells across our watershed. Surface water samples are tested for numerous parameters, including ecoli, nitrates and lead. Groundwater sample tests include nutrients, metals and bacteria.

Water Quality Reports detailing this initiative are produced annually and available for download (pdf): The Water Quality Monitoring Program completed the NPCA Groundwater Study in 2005, the results of which are available here: NPCA Groundwater Study Final Report.

Water Quality data that is collected by the NPCA is now available through the Ontario Ministry of the Environment’s map portal.

This section also administers the Water Well Decommissioning Grant Program, which provides financial assistance to landowners to properly close inactive water wells and ensure they do not become a future threat to ground water quality. For information about the program, and to apply, visit the Water Well Decommissioning Grant Program page.

Watershed Report Cards

The Niagara Peninsula Conservation Authority (NPCA) is pleased to present the 2018 Watershed Report Card—a check up on the health of the Niagara Peninsula watershed, focusing on surface and groundwater quality, forest conditions, and wetland cover.

Since 2005, the NPCA and its partners have produced report cards to inform its residents on the overall health of the Niagara Peninsula watershed. The 2018 Watershed Report Card is part of an initiative by conservation authorities to evaluate key indicators of watershed health with guidelines and grading system provided by Conservation Ontario.

The 2018 report card, despite some low grades, gives a clear snapshot of the status of the watershed in 2018, a baseline against which we can use to measure all future efforts. These grades are typical of watersheds in Southern Ontario. The good news is that the Niagara Peninsula watershed scored well with respect to groundwater quality, and the amount of wetland cover within its area, but there is still some work to do regarding the quality of surface water and forest cover.

The NPCA works in many local, provincial and federal partnerships with governments, other agencies, landowners, and residents to plan and deliver watershed management programs that strive to keep the Niagara Peninsula watershed healthy.

Back in October 2017, it announced eight exciting initiatives which set aggressive targets for improving water resource management and the overall health of the watershed. Environmental health is everyone’s responsibility, and these goals can’t be achieved without the help of the people of the watershed.

The watershed report cards are used to target specific actions to address issues and improve conditions. These actions can result in better watershed health and provide benefits to water quality, fish and wildlife habitat, improved forest conditions and quality of life for residents. It is anticipated that with the help of the people of the watershed, grades will improve over time.

Individuals, community groups, and businesses alike are encouraged to get involved and play a key role in improving the health of their watershed by planting native trees and/or rainwater gardens, sponsor community clean ups to keep waste and garbage out of natural areas, or invest in ‘greener’ alternatives to current practices.

To find out more about what individuals, community groups, and businesses can do to help, please see complete 2018 Niagara Peninsula Watershed Report Card.

Please note: The NPCA’s role is to evaluate the quality of local watersheds and provide that information to the public and our partners. By doing this, the NPCA can measure environmental change, improve local knowledge, focus natural resource management actions where they are needed most, and motivate action in our watershed. The NPCA’s water and land resources provide important ecological, economic, and societal benefits to its residents, and the organization continues to ensure its programs contribute to a healthier watershed.

The NPCA fulfills its responsibility to evaluate the quality of the watershed alongside upper and lower tier local municipalities, The Province of Ontario (MOECC, MNRF and OMARFA) and Environment Canada and Climate Change.

Watershed Plans

The Niagara Water Quality Protection Strategy is a multi-stakeholder initiative based on public and agency consultation. The NWQPS was developed by the Regional Municipality of Niagara in partnership with the Niagara Peninsula Conservation Authority and the Ministry of the Environment, with help from watershed municipalities and local stakeholders. One of the recommendations of the NWQPS was to complete watershed plans for all of the watersheds in the Niagara Peninsula Conservation Authority’s jurisdiction. The NWQPS identified 32 Local Management Areas (LMAs) that is based on watershed boundaries. To this end, the completed watershed plans have adopted the vision as presented in the Niagara Water Quality Protection Strategy:

“Niagara’s watersheds will contribute to an improved quality of life for all living things. There will be enough water, of the necessary quality, to sustain healthy rural and urban communities, in harmony with a natural environment, and rich in species diversity. Citizens and neighbours of Niagara will share the responsibility of efficient water use, and will respect the long-term sustainability of all our water systems and the life that depends on them.”


Source Water Protection

All of us in Ontario have a role to play in protecting our fresh water. Protecting water at its source is the first step in ensuring we all have access to safe drinking water. By stopping contaminants from getting into sources of drinking water, we can provide the first line of defense in the protection of our environment and our health.

Niagara River (Ontario) Remedial Action Plan (RAP)

Restore - Protect - Engage

In the early part of the 20th century, the Niagara River was considered to be the most polluted places in North America. In 1972, Canada and the United States signed the first Great Lakes Water Quality Agreement to clean-up the Great Lakes, including the Niagara River.

Over the past 50 years, major clean-up efforts in the Niagara River have reduced discharges of pollution and toxic chemicals. The Niagara River is on track to be successfully remediated from one of the most degraded places in North America to one of improved health recognized for its contribution to global biodiversity.

Native Plant Suppliers

Native Plants have evolved naturally, growing in your area, and find its’ soil and climate home. Plants from seed sources closest to your site will survive best, having adapted these local soil and climate conditions.

  • For increased plant survival ask for plants/seed with origin from EcoDistrict 37 (7E-3 and 7E5)
  • Order plants by scientific name to ensure native species, and
  • Ensure plants are not endangered or threatened. These plants require very specific areas only.
  • Check the NPCA Native Plant Guide for Native Niagara Plant Species
