Figure 1 . Leftmost map (a) illustrates NCDMF conditional management units with water quality sampling stations. Blue waters correspond to waters that are not approved for shellfish growing and harvesting, while the green areas correspond to the conditionally managed shellfish growing waters. The black points indicate the exact locations of the NCDMF water quality sampling stations and the orange crosses indicate the locations of the weather stations used to gather the precipitation time series data. The middle map (b) illustrates the NCDMF SGAs colored by the first letter of their SGA name. The rightmost map (c) illustrates rainfall thresholds (as of July 2021) for NCDMF conditionally managed areas measured in inches. Dark red indicates a rainfall closure threshold of 1 inch where the lightest white indicates areas with a rainfall closure threshold of 4 inches. Study area maps were created in ArcGIS Pro version 2.8.
