Passby Flow Determination
Determine Chapter 93 Existing/Designated Water Use
Apply Tennant Method for:
Streams Not Covered by IFIM Method Criteria
EV, HQ, and Wild Trout = 25% Average Daily Flow (ADF)
Non- EV, HQ, and Wild Trout and Not AMD-Impaired = 20%
ADF
Partially AMD-Impaired with Some Aquatic Life = 15% ADF
