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?
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.
PO4- PO4- - - + + - SiO2- - Pb2+ + Cd+ - PO4- - + 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) Electrostaticcharges on sediment surfaces can carry nutrients/chemicals
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. Visible sediment load in StoddartCreek
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 After Before
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
