• Spawning areas (>20% of the adult population of a run at a single location for spawning)
• Spawning usually occurs in gravel riffles of small tributary streams, including lake inlet streams.
• Fry associated with low velocity side channels, abundant instream cover (cobble/boulders).
• Adequate instream cover is important for juvenile habitat, and important for overwintering success.
• Low velocity water with sufficient depth for refuge, instream and overhead cover important for adult overwintering.

• Minimize or avoid activities within the RMA of BT occupied streams during spawning and migration periods.
• Maintain the hydrologic characteristics of the site when activities are planned within identified habitat, including: cover, substrate quality, pool depth and volume, large woody debris, groundwater flow, water quality, temperature, and channel structure..
• Plan activities so that key habitat features remain available for use throughout all seasons.

All Activities

• Identify key habitat features using appropriate measures (i.e. QP direction, desktop review, field confirmation, etc) and plan activities within the operating area accordingly.
• Observe riparian setbacks and avoid planning stream crossings within spawning locations and migration corridors.

 

All Activities

• Undertake construction and operation of oil and gas activities in a manner that minimizes impacts to desired plant communities and key habitat features

 

Timing considerations:

• As per EPMG Section 1.6.3.3 Timing Window Guidance for HPW, the proponent must consider and plan riparian works and/or stream crossings within “least risk windows” for Aquatic species in the Peace Region. Refer to Section 4.8 of the Oil and Gas Activity Application Manual for additional information regarding Changes in and About a Stream.

 

Linear Features

All

• Upon completion of the activity, undertake the following measures to encourage re-establishment of the pre-disturbance ecological trajectory:

• deactivate unnecessary access corridors,
• undertake measures to control access,
• promote natural or assisted regeneration.

• Construct necessary crossings to the highest standards to minimize risk of sediment input or impacts to the channel.
