'arks and Recreation Dept. <br />Page 4 of 9 <br />(1) Recreation flow requirements requested in Department instream water right applications <br />shall be based on the methodology in this section. According to this methodology, the <br />recreation flow is the flow or water level needed to accommodate the predominant <br />recreational use(s) occurring during any given month. The Department shall make this <br />determination using the following procedure: <br />(a) Each existing type of recreational use shall be identified and fully described. Each type may <br />have separate, discrete, instream flow requirements and seasons of use. Some stream flow <br />dependent uses may occur on the riverbank including, but not limited to, scenic attraction and <br />wildlife viewing, camping, hiking, boating access, and picnicking; <br />(b) Each type of recreational use shall be described as follows and according to the definitions <br />(OAR 736- 060 - 0010): <br />(A) Time period of recreational use; <br />(B) Stream flow, or range of flows, that support the use depicted by month, or by half -month if <br />appropriate, and quantified in cubic feet per second (cfs), or, if for a lake or other standing <br />water body, in feet above mean sea level or acre feet; <br />(C) Location(s) of recreational use. Locations may be described in any way that provides <br />sufficient details to identify a common location for the use, including by reference to the <br />Environmental Protection Agency's stream reach numbering system or other such <br />documented system in wide use; <br />(D) Experience setting. Reference to the "Recreation Opportunity Spectrum" system of the U.S. <br />Forest Service is helpful, but not mandatory. A discussion of current and planned recreation <br />developments and management programs must be included; <br />(E) Amount of recreational use. The popularity of a stream, river, lake, or wetland, while not <br />the sole basis for instream water rights requests, must be taken into account. The Department <br />will use its best efforts to obtain quantifiable data on actual recreational use. Professional <br />judgment described in relative terms (i.e., low, moderate, or high) may be used when precise <br />data are not available; <br />(F) Competing use(s), if any; <br />(G) Institutional constraints. These may include, but are not limited to: <br />(i) Recreation use permits; <br />(ii) Fishing regulations; <br />(iii) Dam releases; <br />(iv) Minimum perennial streamflows or other instream water rights; <br />http: / /arcweb.sos.state.or.us /rules /OARS_700 /OAR 736/736_060.html 10/30/00 <br />
