“Saving York Factory” Project 2007 Hydrology Report LeeAnn Fishback Scientific Coordinator Churchill Northern Studies Centre January 15, 2008

Overall Project York Factory NHS Overall project goal: to determine a method(s) for stabilizing the riverbank to protect the NHS. Investigate hydrological process affecting riverbank erosion “Saving York Factory”2007 Hydrology Report

Hydrology Project Goals Examine surface hydrology across site Elevation model to determine potential water flows on site Explore subsurface flows with groundwater wells Monitor hydrological components year round Investigate links with historic drains on site “Saving York Factory”2007 Hydrology Report

2007 Hydrology Project Goals Scope of work for borehole installations Equipment purchases Site locations for boreholes Installation of boreholes Data acquisition for elevation model Workplan and ideas for future “Saving York Factory”2007 Hydrology Report

Monitoring Well Equipment Onset Hobo Water Level Loggers Remote point interval measurements Pro: Easy to install and cost effective Con: Can’t be frozen

Sample Processing Borehole samples arrived in Churchill post drilling All samples arrived at Churchill Northern Studies Centre around October 10, 2007 Sorted into various “projects” Samples have been weighed in plastic bags and frozen for further analysis “Saving York Factory”2007 Hydrology Report

Data Acquisition for DEM Digital elevation model (DEM) for site mapping and making hydrological model Working with Manitoba Hydro to get required information “Saving York Factory”2007 Hydrology Report

Wish List for 2008 Hire student for hydrology project Spring snowmelt for surface hydrology Installation of equipment in boreholes Groundwater tests Identify areas for additional measurements Survey of borehole locations Historical drains on site DEM extraction Processing borehole samples “Saving York Factory”2007 Hydrology Report

2008 Wish Visits 5 visits to site 2008 – April – Late May/early June – Early July – End of August – mid to late September Would like a winter visit in 2009 or 2010 “Saving York Factory”2007 Hydrology Report
