Tributary Water Testing

In 2013 the Moose Lake Watershed Society received a Community Initiatives Program grant from the Alberta Government. Riparian areas are portions of the landscape influenced by water along creeks, lakes and wetlands. When properly functioning, these zones are the most ecologically diverse and sustain both fish and wildlife. They provide good water quality and support people on the landscape. The intent of the Riparian Health Inventory is to provide a state of the environment report to the local community. Cows and Fish will continue with the baseline study that was conducted in 2004. By comparing the results from these two Riparian Inventory studies we will be able to produce up to date data and information to the general public.

 


Water sampling was conducted by LARA on the tributaries of Moose Lake which included Thinlake River (two sites), Yelling Creek, Vincent Creek and two smaller unnamed creeks. This sampling will be analyzed for routine chemistry and fecal matter.  

Time 1 samples were collected on June 24, 2013

Time 2 samples were collected on September 30, 2013

From sampling in June to October, the total number of coliforms on average decreased significantly. However the number of fecal coliforms increased greatly. An interesting occurrence at site A, which does not have a large agricultural influence, has the highest number of fecal coliforms. In future it would be interesting to DNA sample to see if it is human caused contamination.

  • Surface waters in this region usually have a pH around 8 due to parent soil materials.

  • Total Dissolved Solids (TDS) is a measure of particles that are greater than 2 microns. Conductivity can be used to measure TDS. The aesthetic objective of TDS for human consumption is less than 500mg/L, but most groundwater TDS is around 1000 mg/L. High levels of TDS are associated with hardness, mineral deposition, corrosion and poor taste. Calcium and magnesium contribute to the hardness of the water. Soft water ranges from 0-50 mg/L, moderately soft from 50-100 mg/L, moderately hard from 100-200 mg/L, hard from 200-400 mg/L, and very hard from 400-600 mg/L.  

  • Of the routine samples, Manganese exceeded the recommended guidelines. Manganese has a large effect on aesthetics of the water. Higher values increase discoloration, odour and taste of the water and will decrease the amount of water consumed which also decreases the productivity of the livestock.
