TO: FROM: DATE: SUBJECT: e e bob0122 CON F IDE N T I A L MEMORANDUM Bob Hykan Ruth Yeager January 22, 1986 National Forest Reserved Rights Claims: Technical Studies; Comments on Letter to be Sent to Prospective Consultants My main comment is that I think we want to give a little more structure to the section on scope of work. If we at least give the consultants the general tasks to be included in the study, it will be both easier for them to write their proposals and for us to compare them. The following is my suggestion as to how this section might be changed. line 18: insert "or can be developed" after "available" line 20: end the paragraph with "matter." Insert the following in place of lines 21 through 55: fhre.~ Below I have outlined ~ main tasks that cover the areas in which the State of Colorado requires technical support. Within each one I have given the major goal, then listed several activities which the consultant might include as means of accomplishing that goal. These items are neither exhaustive nor are they all mandatory; rather, they simply communicate the state's initial thoughts on these studies. Task A: Critique of the Forest Service Methodology. The theoretical basis for the methodology, the means by which the theory is applied to quantify flows, and the applicability of the methodology to the streams involved in the litigation all need to be examined. Any weaknesses in the trail from theory to stream-specific claims need to be documented, and the possible effects of any corrections might have on the quantification need to be analyzed. Possible sub-tasks include: - review of relevant literature - comparison of flows claimed with actual hydrology - field measurements of channel geometry, flows, and sediment transport rates - case studies of streams on which there have historically been significant diversions - computer modeling of effects of diversions on sediment transport
