Saskatchewan Restricted Activity Timing Windows for the Protection of Fish and Fish Habitat
Restricted activity timing windows have been identified for Saskatchewan lakes, rivers and streams to protect fish during spawning and incubation periods when spawning fish, eggs and fry are vulnerable to disturbance or sediment. Restricted activity periods are determined on a case by case basis according to the species of fish in the water body, whether those fish spawn in the spring or fall/winter, and whether the water body is located in Northern, Central, or Southern Saskatchewan.
(Note: Central Region includes the Churchill River).
How To Determine Timing Windows
- Determine the fish species living in the water body where you wish to do work.
- Determine if the fish living in the water body spawn in the spring or fall/winter according to Table 1. There may be one or both spawning types in any given water body. In Saskatchewan, essentially all lakes and streams contain one or more of the spring spawning fish listed, however far fewer contain fall/winter spawning fish.
- Determine if the water body is located in Northern, Central, or Southern Saskatchewan according to Figure 1.
- Use Table 2 to determine the in-water work timing restrictions according to the location of a water body (Northern, Central or Southern) and the type of fish found within (spring or fall spawners). During these periods work should be avoided.
