Hydrologic Concerns

* Elevated water levels persist on many area streams and rivers.
  Additional rainfall may bring sharp rises to water levels. Higher
  than normal water levels may continue through the weekend.

* Many lower locations along rivers such as gravel bars and other
  spots popular for camping and recreating may become
  inundated with water.

* Heavy rain may result in localized ponding in low-lying areas and
  locations with poor drainage.

Next Steps

* Residents along area streams as well as river users and
  recreationists should anticipate higher than normal water levels
  and are advised to monitor weather and river forecasts.

* Reports on river conditions may be sent to the river forecast
  center by calling 1-800-847-1739.
