(A) The water bodies listed in table 8-1 of this rule are ordered from downstream to upstream. Tributaries of a water body are indented. The aquatic life habitat, water supply and recreation use designations are defined in rule 3745-1-07 of the Administrative Code. The state resource water use designation is defined in rule 3745-1-05 of the Administrative Code. The most stringent criteria associated with any one of the use designations assigned to a water body will apply to that water body.
(B) Figure 1 of the appendix to this rule is a generalized map of Ohio outlining the water body drainage basins and listing associated rule numbers in Chapter 3745-1 of the Administrative Code. Figure 2 of the appendix to this rule is a generalized map of the Hocking river drainage basin.
(C) RM, as used in this rule, stands for river mile and refers to the method used by the Ohio environmental protection agency to identify locations along a water body. Mileage is defined as the lineal distance from the downstream terminus (i.e., mouth) and moving in an upstream direction.
(D) The following symbols are used throughout this rule:
* Designated use based on the 1978 water quality standards;
+ Designated use based on the results of a biological field assessment performed by the Ohio environmental protection agency;
o Designated use based on justification other than the results of a biological field assessment performed by the Ohio environmental protection agency; and
L An L in the warmwater habitat column signifies that the water body segment is designated limited warmwater habitat.
