A small watershed and nearby spring feed the lake.

One reason is the limited runoff from their small watersheds.

Numbers 1 and 9 are used for the small watersheds on the edges of the strait.

Channel slope and rainfall intensity become the third most important factors for small and large watersheds, respectively.

Since these calculations involve many assumptions, they tend to be more accurate for either smaller watersheds or when expressed as longer period averages.

This is a result of the underdeveloped soils found in its relatively small watershed.

The relatively small watershed, contained mostly within the town of Calamus, is entirely rural with no cities or villages.

Restricting mountaintop mining to small watersheds could substantially impact the amount of extraction that takes place.

As for floods, they can also substantial, considering the relatively small watershed.

Research in the 1960s focused on effects of logging on water, sediment, and nutrient losses from small watersheds.
