  3. 3. Water Quality Monitoring – Improvements with SLIPPBefore SLIPP With SLIPPSeveral agencies (5) and local Coordinated water quality monitoring in thegovernments (5) monitored water quality in Shuswap Lake all serving the sameShuswap Watershed independently and objectives.with different objectives.No data sharing. Data sharing and integrated reporting.Many small independent or non-published Goal to create one data base.reports.Monitoring duplication between agencies. Sampling programs coordinated and streamlined.Insufficient sampling due to limited funds Sampling programs include objectives forwithin each agency. more than one agency. Shared funds ensure sufficient sampling.Studies provided information on specific Monitoring information of all projects willissues and areas. 3 provide a picture of overall water quality health.

  17. 17. Monitoring under SLIPP – 1st Year - Results Summary•  Generally Increased organic Nitrogen in Main, Sicamous and SalmonArm in 2011 compared to historic data (2003-2008)•  Slight increase of phosphorus at Sandy Point in Salmon Arm fromhistoric data (2003-2006). Increase was already observed in 2008.•  Large tributaries contribute significantly higher nutrient loadings thansmaller streams (even nutrient poor streams such as Adams andSeymour).• Shuswap River provided the highest Nitrogen, Phosphorus and OrganicCarbon Loading into Shuswap River System during Mar-Apr (Low-Land-Runoff) and June-July (High-Elevation Snow Melt).•  Salmon River Nitrogen and Organic Carbon Loadings are similar toAdams, but Phosphorus loadings similar to Shuswap River during peakflows.17
