Attention Burnt River Residents

Kawartha Conservation, in partnership with and on behalf of the City of Kawartha Lakes, is undertaking a flood plain mapping study for Burnt River, between Cameron Lake to the Village of Burnt River, to plan future development and prepare for possible flood emergencies during heavy rains or rapid snow melts. As part of this study, we will be doing survey work within the area during the next few weeks.

To facilitate this study, starting in mid-June, Kawartha Conservation staff and surveying consultants will need to access Burnt River resident properties to gather elevation data and survey water crossings, such as culverts and channel cross-sections.

No personal information will be collected during this time. The survey information will be used to develop a computer model to assist in mapping the Burnt River flood plain.
Staff and consultants will endeavor to contact homeowners while in the area before accessing their property.

NOTE: If you do not wish staff to enter onto your property, please contact Galen Yerex at 705.328.2271 ext. 237 or This email address is being protected from spambots. You need JavaScript enabled to view it..

We are also asking for your assistance gathering information on historical flooding in your area. If you have observed any flooding in your neighbourhood in the past, please assist us by contacting the above to provide details such as the date and location.

Flood plain studies are being conducted to assist the City of Kawartha Lakes in generating accurate hydraulic and hydrological models which will provide regulatory flood lines for the study areas on the map below. Flood plain models will also provide a baseline for developers to use to ensure future development proposals do not negatively impacted others within and close to the existing flood plain. The information will also benefit the City of Kawartha Lakes Emergency Management Planning process to plan and deal with future flood emergencies.

Project Initiation and Development

Several areas in the City of Kawartha Lakes have been identified as flood damage centres through various studies and observed events. These areas are typically not well defined by detailed modeling exercises which would provide clarity of the flooding extent. This becomes particularly important in urban areas, where additional runoff can be expected. To clarify the extents of these flood damage centres, this study was initiated.

Developing and updating flood plain mapping for the priority flood damage centres was included as a Strategic Action within the Kawartha Conservation Strategic Plan (2012 to 2016). We assisted the City of Kawartha Lakes in acquiring LIDAR data for urban development areas and the drainage areas of flood damage centres identified by the study area.

In 2012, we began a survey flood plain mapping project, funded and supported by the City of Kawartha Lakes, to complete and/or update flood plain mapping for ten priority flood damage centres. The Ops Drain # 1/Jennings Creek watershed was selected as the highest priority and was initiated first. The map below indicates the 10 study areas as well as the current order of priority.

The project is guided by a technical committee consisting of representatives from the City and Kawartha Lakes, Kawartha Conservation, Ministry of Transportation (as necessary), and technical advisors from Ganaraska Region Conservation Authority. The Technical Committee gathers frequently for meetings and working sessions over the course of the studies. A peer reviewer has also been contracted to verify the efficacy of modeling procedures and results.

A brief summary of the flood plain study process

Flood plain studies involve an assembly of required information; some existing, some which needs to be collected. Almost all of this information is stored in GIS format and is then transferred into the computer models. Below is a list of several types of information required:

  • Elevation data (from both LiDAR, manual survey, previous works)
  • Land use (both existing and future determined from planning documents)
  • Impervious surfaces
  • Flow paths for surface run off and in-channel flow
  • Precipitation data
  • Key flow nodes where sub catchments input water flow
  • Existing storm water management plans and infrastructure detail plans
  • Culverts and other infrastructure sizing and attributes
  • Location of channel cross sections and their elevation profile.

The various data are then used in the hydrology and hydraulic models along with various precipitation events to determine the resulting water surface elevations for each event. The highest resulting water surfaces are then used to identify the regulatory flood line. Throughout the entire process, the input data and results are confirmed by a water resource engineer and technical committee to ensure that the information used and decisions best reflect the system in study. Results are also sent to a water resource engineer at another agency to peer review the processes and results to ensure they are correct and meet industry standards.

Study 1 - Ops Drain No.1/Jennings Creek, Lindsay - Complete

Located north and west of the Town of Lindsay, this area drains both urban and rural lands to the Scugog River. The Ops #1 Drain and the lands it drains are very flat which has resulted in difficulty in completing previous flood plain and storm water assessments in the past. With the acquisition of LIDAR data an accurate base data is now proposed which has been identified as a requirement for study completion in past reports.

Flood Plain Management Policies

Policies have been developed for where there is a risk to flooding in the Ops #1Drain/Jennings Creek watershed. The goal of these policies is to guide and regulate existing and future development in order to protect personal safety and property.

Study 2 - Sinister Creek, Lindsay – Completion 2016

Located northeast of the Town of Lindsay, this area drains both urban and rural lands to the Scugog River. A new flood plain study will be created for this watershed within the urban area of Lindsay. The watercourse has a number of crossings in the Colborne Street East area of town and runs through Rivera Park before entering the Scugog River downstream of the Lindsay dam.

Study 3 - Fenelon Falls North, Fenelon Falls – Completion 2016

Located north of the Fenelon River, this water course drains both rural and urban areas to the Fenelon River upstream of the Falls. This watercourse also has a large enclosed section from Francis Street to the river outlet. A Flood Damage Reduction Study was completed in 1996 identifying flood lines and hazards for the area. The new flood plain study will build on the existing information and provide more detail using the LiDAR elevation data.

Study 4 - Omemee East Tributary, Omemee

This watercourse drains mainly rural lands east of Omemee and south of Highway #7 and outlets to the Omemee Mill Pond after crossing Queen Street South. Previous reports have identified flood elevations for the Mill Pond and this study will use this information as a starting water level. Further mapping based on the hydrology and hydraulics of this channel will be completed within the village’s future urban boundary.

Study 5 - Bobcaygeon Tributary, Bobcaygeon

Located north of the village of Bobcaygeon this tributary drains a large rural section before entering the village’s urban boundary and outlets to Big Bob Channel. Interestingly this channel is kept separate from Big Bob Channel west of the dam by a concrete barrier since the lake water is higher and then outlets below the dam once the receiving water surface is low enough. A flood plain study will be completed within this area of Bobcaygeon.

Study 6 - Fenelon Falls South, Fenelon Falls

Located south of Fenelon Falls this tributary drains rural and urban lands to Sturgeon Lake just south of the Fenelon River. This tributary potentially shares an upstream drainage area with another watercourse draining north to the Fenelon River. This phenomenon will require additional attention to ensure amounts of upstream water entering the downstream section is accounted for adequately. A flood plain study will be completed within this area of Fenelon Falls.

Study 7 - Burnt River

Burnt River drains a very large area north of Cameron Lake and flooding occurs commonly on this river. An existing flood study was done previously by the Ministry of Natural Resources; this study will be used to support development of updated hydrology and hydraulic models using LIDAR data, which will provide tools to assess low frequency events which also results in threats to people and their property.

Study 8 - Mariposa Brook, Little Britain

The Mariposa Brook has a large watershed which drains mainly rural agricultural lands. Two large sections of the brook join immediately downstream of the village of Little Britain, and just north of Little Britain Road. Little Britain has had flooding in the past and a previous report has been completed. New models and regulatory mapping will be completed to better understand the system and the flooding extent that can be produced.

Study 9 - McLarens Creek, Cambray

McLarens Creek drains land from Goose Lake through the village of Cambray and outlets to Sturgeon Lake after crossing Highway 35. A small dam also exists within the village north of Cambray Road. A flood plain report will be produced for the village of Cambray.

Study 10 - Emily Creek Tributary, Dunsford

This tributary drains rural lands west of Dunsford before flowing through the village and then along and under County Road 36 before entering the Emily Creek south of County Road 36.flood plain models and mapping will be developed for the village of Dunsford.
