Memo 

To: Members of the Technical Work Group 

From: Mary Orton for the AMWG Ad Hoc Committee on Strategic Planning 

Date: February 28, 2000 

Re: Attached WORKING DRAFT of Management Objectives 

Attached please find a work in progress – draft management objectives for the AMWG goals. 

Please review these before your meeting on March 2, when they will be discussed. We would 

like to have your comments on the following questions: 

a. Are these MOs necessary and sufficient to achieve e the goal? 

b. Do the MOs fit the new definition of MO (also attached)? 

c. Is the goal properly stated? 

d. Are the metrics correct? 

e. Are the current and target levels correct? 

f. Are the MOs consistent with our guiding documents? 

g. Does the text in the “Purpose” column fit one of these four purposes: hypotheses, linkages 

to other goals, assumptions, notes when the stated element and attribute are surrogates. 

Please note the following about the chart: 

1. At the end of the chart, there is a list (by Goal and MO) of Information Needs, Management 

Actions, and Notes. These were captured during this process, and although they are not 

complete, they can amplify your understanding of the MOs. (Not every Information Need that 

is noted in the “current level” and “target level” column is listed here.) The full list of INs and 

MAs will be developed during a process to follow. 

2. If the committee was not able to put a number in the “current level” or “target level” column, 

they did indicate the method they would use to fill in the blank. The methods are: 

The number will be obtained from the literature; 

The number will be developed through an Information Need, that is, through research; or 

The number will be developed through a specific Decision Process (see #3, below). 

3. The Decision Process is a one in which the target is developed within the range of 

operational flexibility (ROF) of the dam, taking into account the range in which the target 

resource(s) thrive (RTR), and the Range of Natural Variability (RNV). 

4. Where there are data in the “current level” or “target level” columns, the source of the data 

will be footnoted in the final MO table. 

5. Where there is a number in the target level, remember that those data will be validated 

through the monitoring program. 

6. Some questions will be answered before going forward on the Information Needs. One 

example of this is the question under MO 3, “Is this a cost-effective measure?”

Goal 1. Protect or improve the aquatic foodbase so that it will support viable populations of species at higher trophic levels. 

____________________________________________________ Old MOs: BRMO 1: Maintain and enhance the aquatic food base in the Colorado River ecosystem to support desired populations of native and non-native fish. At a minimum, maintain continuously inundated areas for Cladophora and aquatic invertebrates at or above 5,000 cfs discharge levels from Glen Canyon Dam. BRMO 2: In the Colorado River downstream of Glen Canyon Dam to the confluence of the Paria river, sufficient ecological conditions (such as habitat, foodbase and temperature) should be maintained, which in conjunction with management by Arizona Game and Fish will produce a healthy self-sustaining population of at least 100,000 Age II+ rainbow trout that achieve 18 inches in length by Age III with a mean annual relative weight (Wr) of at least 0.90.
