bull shark. This includes the following WBIDs; 1339, 1341I, 1345A, 1373, 1382, 1440AB, 1479, 1508, 1528, 1528A, 1528B, 1528C, 1535, 1538, 1554, 1562, 1567,

### Where a parameter was 1998 303(d) listed, the priority for TMDL development is the year provided and is assigned based on the consent decree schedule. Where a parameter was only identified as impaired under the IWR, a priority of “medium” was assigned. Exceptions are waters where the impairment poses a threat to potable water or human health, which have been assigned a “high” priority, and fecal coliform impairments, which have been assigned a “low” priority. All other listings as of this cycle are prioritized based on the following: it is the Department's intent that listings with a "High" priority be addressed within the next 5 years, listings with a "Medium" priority be addressed within 5-10 years as resources allow, and listings with a "Low" priority be addressed within the next 10 years.

The Group 5 Springs Coast Basin Verified List is based on IWR Run 29 except for WBID 1709F, which uses data from IWR Run 28-2.
