Aquatic Invasive Species

Aquatic Invasive Species - Zebra Mussels

Installation of a sampler

We distributed substrate samplers around Pike Lake, Blackstrap Lake, Brightwatwer Reservoir, and Lake Diefenbaker to monitor the possible spread of Zebra and Quagga Mussels. Once a month SSRWSI employees checked each sampler for evidence of Zebra Mussels and uploaded the information on the Survey123 App (form-centric data collection GIS App). For the summer 2019 season, no Zebra Mussels were reported. This project is funded by the Government of Saskatchewan through its Fish and Wildlife Development Fund.

Veliger sampling training

In June, we, and five other watershed stewardship groups, attended a veliger sampling training session provided by the Government of Saskatchewan’s Fish, Wildlife & Land’s Branch. Altogether, 120 waters, within 12 of the major 16 watersheds in the province (not those way up north), were sampled. The results for this year came back negative for invasive mussel larvae!

Veliger sampling in action

Over the course of three months, SSRWSI took samples at Lake Diefenbaker (Riverhurst and Elbow docks) and Blackstrap.

SSRWSI also participated at several community events throughout the summer to educate the public on Aquatic Invasive Species.


The Ministry of Environment has established an aquatic invasive species (AIS) prevention program focusing on raising public awareness to protect Saskatchewan’s waterways from the spread of harmful AIS.

Quick facts:

  • Zebra and quagga mussels are virtually impossible to eradicate.
  • Once introduced and established, they can spread rapidly – with one female producing up to a million eggs per year.
  • Invasive mussels can disrupt natural food chains, create toxic algae blooms decrease property values and reduce recreational enjoyment of natural areas.
  • Can cause millions of dollars in damage to water-operated infrastructure and can clog water supplies to SaskPower facilities, hindering power generation.
  • These mussels also pose a risk for cottages and homes that rely on these waterways for their water supply.
  • Any freshwater mussel that is attached to your equipment is an invasive mussel and should be reported to the TIP line.
  • Washing your boat with hot water and following the CLEAN, DRAIN, and DRY protocol will greatly reduce the threat of spreading these species.
