Abstract/Description or Keywords The guidelines presented in this report are founded on the beliefs that it is possible and desirable to
manage our watersheds and their natural surroundings in a sustainable manner and that sustainable
management is the shared responsibility of all stakeholders, including proponents, professionals
and all levels of government. This report provides risk-based management guidelines for fish
habitat on the shoreline of Mabel Lake under which proponents and qualified professionals can
proceed with common, low-risk works without review by Fisheries and Oceans Canada (DFO), but
where specific, detailed design and assessment information is required by DFO for review of less
common, higher-risk works.
The guidelines presented in this report are based on technical results of shoreline inventories
recently completed on Mabel Lake as part of the larger Shuswap Watershed Mapping project.
These inventories provided important background information concerning fish habitats that occur
on Mabel Lake and fish habitat impacts caused by common development activities. The guidelines
are intended to protect and restore important fish habitat values, consistent with conservation and
restoration goals of the DFO Policy for Management of Fish Habitat (DFO, 1986) and concerns of
residents expressed in the Kingfisher Local Area Plan (MMM Group and Site 360, 2010). These
guidelines do not address development risks to non-fish species (e.g., reptiles), or riparian or
upland ecosystems that do not also provide fish habitat (e.g., provincially モred-listedヤ cottonwood
riparian ecosystems on large river floodplains) because the assessment only includes features that
are within 50 meters of the high water mark. Additional inventory and mapping projects such as
Sensitive Ecosystem Inventory would be required to address concerns related to wildlife species
and ecosystems along the shoreline.
A solid understanding of aquatic and riparian fish habitat values, common development activities
and the effects of these activities on fish habitat is required to identify and differentiate low and
high risk works. Foreshore Inventory and Mapping (FIM) is a standardized, spatially explicit
shoreline inventory methodology that was employed to map the shorelines of Mabel Lake. This
methodology has been used to map the shorelines of other BC lakes and provides a common basis
for integrating environmental information into land use guidance documents.
Guidelines presented in this document are based upon the FIM methodology and data collected
during FIM surveys. These guidelines are the final step in an inventory and management
framework that has been previously applied to other lakes in the Shuswap, Okanagan and
Kootenay regions of BC:
1. Shoreline Inventories following the FIM methodology were completed using a variety of
techniques and data was derived from numerous sources (Schleppe, 2009c). These baseline
inventories provided an understanding of the current condition of foreshore areas of Mabel
Lake.
2. An Aquatic Habitat Index (AHI) was generated using FIM data to determine the relative fish
habitat value of mapped shoreline areas (Schleppe, 2009c). This index employed similar
methods to previous AHI projects on Shuswap, Mara, Moyie, and Monroe Lakes (Schleppe,
2010a; Schleppe, 2010b). 3. Shoreline management guidelines contained within this document were prepared for mapped
shorelines to clarify and streamline review processes for development activities that may
impact fish and fish habitat. These shoreline management guidelines will better inform
proponents, professionals and government agencies of risks posed to fish and fish habitat by
development activities that would alter the lake shoreline.
Key deliverables for this project include a map of the shoreline of Mabel Lake in which individual
shoreline segments - or モvulnerability zonesヤ - were colour-themed based on their current relative
habitat value. Under this system, red shoreline segments represent the highest value fish habitat
areas, receive the highest level of protection and require the most detailed project design and
assessment information to support agency and local government reviews. In contrast, green
shoreline segments represent areas of lower habitat value or areas that have been significantly
impacted by past development where common, low-risk works may proceed under existing
guidelines without DFO review. Application of present-day development guidelines to all
shoreline segments is expected to maintain current fish habitat values of natural areas while
gradually recovering fish habitat values lost to past development impacts. This gradual recovery
of fish habitat is required because the extent of development-related impacts that has been
documented to occur without appropriate best management practices in place to mitigate these
impacts is now noticeable (e.g., extensive substrate modification due to groynes or removal of
important riparian vegetation to create "landscaped" areas consisting predominantly of turf).
Relative risks of common development activities were also recorded in tabular format for the full
range of relative habitat values and tables and flow charts were developed to guide proponents,
professionals and practitioners through project assessment, reviews and works.
This report only provides guidance related to conservation and protection of fish habitat values. It
does not consider other development factors such as erosion hazards, drinking water quality or
navigation as these lie outside of the current scope of work and require data that is not adequately
collected following the FIM methods. Also, guidelines and review processes detailed in this report
apply only to fish habitat protection requirements of the federal Fisheries Act as administered by
DFO on Mabel Lake. It remains the obligation of proponent, professionals and other government
agencies to ensure compliance with other legislation that may apply to their projects.
