14.4 Developing a sustainable source of high quality groundwater for the Okanagan sockeye fish hatchery

Presented By: Douglas Geller, Western Water Associates Ltd.
Time: Tuesday, 3:50 - 4:20 PM

In 2014, the Okanagan Nation Alliance (ONA) together with its project partners will commission the Okanagan Sockeye fish hatchery in Penticton, B.C. that is the culmination of nearly a decade of planning intended to reintroduce Sockeye to the lakes above Okanagan Falls. In 2006, ONA commissioned a feasibility study to evaluate two candidate sites for a permanent hatchery and determined that a site near Penticton was preferred. Successful rearing of Sockeye requires a source of consistently cool (10-12 degree C) groundwater that is disease-free, and of a high aesthetic quality. To confirm that such a source was available at the Penticton site, ONA completed a series of groundwater investigations between 2007 and 2009, involving test wells, aquifer testing, water quality monitoring, and pilot-scale treatment studies. The Shingle Creek aquifer at the site proved to be a productive, high quality source, with the only concern being slightly elevated iron.

The initial hatchery phase requires up to 150 L/sec of groundwater, and at full buildout, up to 225 L/sec. Following the completion of a federal (CEAA) environmental assessment for the hatchery project in 2012, the full-scale groundwater production facilities were constructed in 2012-2014. When the hatchery begins operations in the late summer of 2014, there will be three 400 mm (16 in) diameter production wells with capacities ranging from 57 to 95 L/sec. (900 to 1,500 US gpm). As part of the environmental assessment process, a long-term groundwater-monitoring program was designed to help the ONA keep track of water use and how the aquifer responds to pumping.

14.5 A decision support tool for surface water resource management in Northwest BC

Presented By: Benn Kerr, Foundry Spatial Ltd.
Time: Tuesday, 4:20 - 5:50 PM

A representative model of streamflow across Northwest BC has been created using detailed climate, topography, and vegetation information. Streamflow estimates were generated using a combined water balance and statistical approach. These estimates were then integrated with BC Freshwater Atlas watershed data and information on existing water allocations and environmental flow needs to support the development of a decision support system. The decision support system uses a map based interface to provide users with a watershed based view of the monthly water availability data for any location in the Skeena Region of the Ministry of Forests, Lands and Natural Resource Operations. This approach builds upon the learning from the development of the Northeast Water Tool (NEWT), and extends on its capabilities by also providing the results of hydrometric analyses for gauged watersheds in the study area, including the recent update to the Skeena Streamflow Inventory. This presentation will describe the challenges and solutions encountered during the modeling process as well as the guiding principles and objectives for the development of the decision support tool - the capabilities of which will be demonstrated.
