| Much of the dense brush was limited to rivers, creeks, drainages, and in small mottes on the prairie. |
| In springs of average to high runoff, a few drainages may prove unfordable, requiring a detour. |
| These drainages envelop the ephemeral wet surfaces and subterranean systems that rarely hold a diverse molluscan fauna. |
| As is illustrated by Lake Nokomis, some drainages have been altered by the construction of dams and artificial channels. |
| Approximately two acres of vernally significant ephemeral drainages and pools have been noted in the Blue Oak-Gray Pine Woodland. |
| A southern taxonomic form is distributed in North America in Pacific drainages from northern Washington north to the Alaska Peninsula. |
