Shellfish harvesting waters in Virginia classified as "Conditionally Approved" are in the OPEN status unless a 'condition' has been met. If the condition has been met, the waters identified immediately below will convert to CLOSED (Restricted) status for a set duration of time.
Rainfall-based Conditionally Approved waters are in the CLOSED status for ten days, and open on the eleventh day, when a rainfall 'condition' occurs. When rainfall exceeds the condition threshold for a 24-hour (8pm - 8pm) period, these waters will close.
Unless otherwise classified as condemned by separate order, the current status of Rainfall-based Conditionally Approved Areas for the harvest of oysters, clams and mussels as of Sunday, March 29, 2026:
Yeocomico River and tributaries Conditional Area Sections C23 and C24, Conditional Area Sections C8, C25, C26, and C27
- OPEN.
Poquoson River and tributaries Conditional Area Sections C10 & C11, Conditional Area Sections C12 & C13, and Conditional Area Sections C14 & C16
- OPEN.
Back River and tributaries Conditional Area Sections C21, C28 & C31, Conditional Area Sections C22 & C29
- OPEN.
