Water Quality Monitoring – Improvements with SLIPP

Before SLIPP With SLIPP

Several agencies (5) and local governments (5) monitored water quality in Shuswap Watershed independently and with different objectives.

Coordinated water quality monitoring in the Shuswap Lake all serving the same objectives.

No data sharing. Many small independent or non-published reports.

Data sharing and integrated reporting. Goal to create one data base.

Monitoring duplication between agencies. Insufficient sampling due to limited funds within each agency.

Sampling programs coordinated and streamlined. Sampling programs include objectives for more than one agency. Shared funds ensure sufficient sampling.

Studies provided information on specific issues and areas.

Monitoring information of all projects will provide a picture of overall water quality health.

Summary

•  Generally Increased organic Nitrogen in Main, Sicamous and Salmon Arm in 2011 compared to historic data (2003-2008)

•  Slight increase of phosphorus at Sandy Point in Salmon Arm from historic data (2003-2006). Increase was already observed in 2008.

•  Large tributaries contribute significantly higher nutrient loadings than smaller streams (even nutrient poor streams such as Adams and Seymour).

• Shuswap River provided the highest Nitrogen, Phosphorus and Organic Carbon Loading into Shuswap Lake System during Mar-Apr (Low-Land-Runoff) and June-July (High-Elevation Snow Melt).

•  Salmon River Nitrogen and Organic Carbon Loadings are similar to Adams, but Phosphorus loadings similar to Shuswap River during peak flows.
