O&G Activities and the Charlie Lake Watershed Presentation by Allan Blair OGC SCEK Fund Workshop June 10, 2004
Agenda Charlie Lake Watershed What are the issues? Strategic Environmental Plan for the Charlie Lake Watershed Run-off – a sediment primer Oil and Gas activity successes Future work More information?
Charlie Lake Watershed
What are the issues? Major concerns*: –lake water quality –recreational fishery –other recreation uses Other concerns: –maintaining bird and wildlife habitat *Based on CLCS/PRRD survey of concerns from lake residents and users
Strategic Environmental Plan Key Areas for improvement upgrading of poorly functioning stream crossings (primarily culverts that pass under roads) Preventing run-off from oil and gas sites, agricultural and lakeshore development sites reducing impacts from isolated septic systems.
SiO2- PO Cd+ Pb2+ Electrostatic charges on sediment surfaces can carry nutrients/chemicals Run-off – a sediment primer Fine sediments (silts, clays) can carry nutrients and chemical contaminants Suspended sediment reduces water clarity - Affects growth of bottom algae (basis of food chain) Reduces hunting success of predatory fish (fish are generally visual hunters)
Visible sediment load in Stoddart Creek Run-off – a sediment primer (cont’d) Can cover over important fish spawning areas Over time lakes fill in. As lakes shallow, turbidity increases and algae- bloom related problems worsen. Erosion ultimately results in the loss of valuable land.
Oil and Gas activity in the Watershed 130 oil/gas and related industrial sites Oil field roads
Oil and Gas – culvert / road restoration Before After Site Restoration – road and culvert removed
Oil and Gas - site drainage Before After
Scope of Future work OGC SCEK matching funding for 2005 ID sites with opportunities to remedy or mitigate ongoing erosion issues Expand efforts in working with well site operator, OGC and land owner Develop strategies and a plan of action to deal with the identified erosion issues Explore best practices for erosion control for future development
