Abstract/Description or Keywords British Columbia Timber Sales and and the Powell River Community Forest provide funds to the Powell River Salmonid Enhancement Society for monitoring water quality throughout the Haslam Lang Community Watershed. This report presents 2011 data (as well as selected 2010 data) and discusses progress of the water quality monitoring program to date.

During 2011, the automated monitoring station located at the Salmon Enhancement Society Counting Station at the mouth of Lang Creek continued to record stage, rainfall, turbidity, and water and air temperature on a continuous basis. Stage, water and air temperature data was deemed reliable with sensors working properly. Unfortunately turbidity data was rejected in its entirety. The rainfall meter appeared to be working but the calibration must have been off and so rainfall total was underestimated.

Bi-monthly, on-site sampling has been carried out by the Powell River Salmonid Enhancement Society at six strategic locations within the watershed throughout the 2011 season. This data has been collected from 1997 to present with a two year gap (2006, 2007) and provides an excellent historic record of variability of water quality parameters. As well as capturing water quality data at distinct points in time at a number of locations, the repeated visits of the observer to sites throughout the watershed enhanced the understanding of local sediment generation problems.

Water temperature recorders, (Hobos) have been employed in 2011 on Anderson Creek, Blackwater Creek and at the hatchery on upper Lang Creek. This continuous temperature data was of high quality and provides important insights into temperature fluctuations during the critical maximum high water temperatures of summer.

The hydrograph developed from lower Lang Creek data indicated a peak flow of 30 m3/sec in a mid November storm whereas in December 2010 there was a peak flow measure at 62 m3/sec. Summer low flow appeared to be similar with those in 2010, albeit not such a long duration. Management of the weir outlet and sluice gates strongly influences both high and low flow on Lang Creek.

As a result of non-participation of the Ministry of Environment, no water samples were analyzed by laboratory in the 2011. Last year that laboratory samples were analysed was 2009

All digital data, well beyond what can be presented here, is archived at the office of the Powell River Salmonid Enhancement Society and can be made available to interested users.

Recommendations are provided to fine tune efficiency of the monitoring program. As mentioned in last year’s report the existing turbidity meter at the mouth of Lang Creek should be removed from service. Recalibrating the low discharge portion of the rating curve is also recommended. The rain gauge should be checked and recalibrated.
