A risk-based adaptive management framework ECCC conducts the monitoring and surveillance activities based on the level of risk to water quality in a watershed. Near-perfect matching; little to no variation in color, tone, luster, shape or size.
For the modern shells five recently dead Actinonaias ligamentinaindividuals grew faster compared to some relic specimens of the same species and comparable age, with thicker growth annuli being observed in particular specimens. Strands will display spotting and blemishing.
There are many regional Freshwater quality planning efforts that encompass all or a portion of this watershed. 2007for example, Freshwater quality models showing a projected increase in schistosomiasis around the Three Gorge Dam and the Dongling Lake Region in China based on predicted hydrological and epidemiological data.

One federal-territorial site is found in Yukon.
Some of the year-to-year variation can be explained by variations in precipitation and runoff.
