Yentna at Lake Creek.

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

* 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 recreators
should anticipate higher than normal water levels and are advised
to monitor weather and river forecasts.
