How can I identify activities that may impact fish habitat in a watershed through a desktop analysis?

You can examine the area around the river and look for features related to forestry or agriculture, developments such as bridges, dams, weirs, and culverts, and habitats such as scour holes, riffles, and erosion sites. You can also measure the wetted width of the channel, evaluate the stability of the channel’s meanders by measuring their radius, and measure the meander length to see if it falls within the expected range of 10–14 times the channel width. By comparing the predicted and observed characteristics of the river, you can identify areas that may be candidates for restoration due to unstable banks or other potential habitat issues.
