Spectral imagery of plumes or suspended material.Fish activity that resuspends sediments.Shallow or poorly developed root systems.Consider including SS as a candidate cause when the following sources and activities, site evidence or biological effects are present: For more information on specific entries, go to the When to List tab. It can help guide you in collecting evidence to support, weaken or eliminate SS as a candidate cause.

The checklist below will help you identify key data and information useful for determining whether to include excessive SS among your candidate causes. This diagram and other supporting information also may be useful in Step 3: Evaluate Data from the Case. Example of insufficient sediment, resulting from retention of sediment behind dam and periods of high flow downstream of Skelton Dam, ME.Įxcessive SS should be included as a candidate cause when potential human sources and activities, site evidence, or observed effects support portions of the source-to-impairment pathways (Figure 1).
