PHWH Aquatic Life Use Designations (continued) 3.If HMFEI results are questioned and no cold-cool water vertebrates are present, identify macroinvertebrate voucher sample to lowest taxonomic order a. If 4 or more cool water taxa then assign Class III PHWH stream b. If fewer than 4 cool water taxa then assign Class II PHWH stream
