<br />e <br /> <br />e <br /> <br />e <br /> <br />1693 <br /> <br />cause and effects relationships between dam operations, or other driving <br />variables, and resource responses (e.g., how IS the abundance and composition <br />of benthic invertebrates affected by grazers, predators and dam operations?). <br />Research requires a purposeful design with established statistical criteria, <br />Including allowable errors for accepting and rejecting null hypotheses. Research <br />may also result In the collection of data that can be used to help determine or <br />refine Core MOnitoring Information Needs. <br /> <br />. Supporting Information Need (SIN): A SIN contributes to understanding the <br />basis for a resource response and its link to other resource management goals. <br /> <br />. Status and Trends: Status refers to the condition of a resource at a given time or <br />place. Trends refer to a statistically based temporal or spatial series for a given <br />resource, during the periods and at the locations where data were collected. <br /> <br />. Cause and Effect: Cause and effect assigns a resource response to a particular <br />event(s) or driving variable(s). <br /> <br />. Glen Canyon Dam Operations: Glen Canyon Dam operations refers to the <br />operation of the power plant and other release structures, such as bypass <br />structures, spillways, and potentially a temperature control device among others. <br />Their uses conform to applicable law. The AMWG develops recommendations <br />for all of the dam's structures to further the purposes of the GCPA and meet the <br />environmental commitments in the EISIRecord of Decision on the operations of <br />Glen Canyon Dam. This is done within the limits of the Record of Decision <br />andlor through experimentation. <br /> <br />. Record of Decision Operations: Record of Decision operations are defined as <br />the modified low fluctuating flow alternative described in the Record of Decision <br />including restrictions on upramp and down ramp rates, the allowable range of <br />daily fluctuations and the allowable minimum and maximum daily flows. In <br />addition operations Include beach/habitat-building flows (up to 45,000 cfs) habitat <br />maintenance flows (up to power plant capacity) and any flows defined as <br />experiments within the environmental commitments of the Record of Decision. <br /> <br />NOTE: The MOs presented in this document represent language that has been <br />extracted and paraphrased from the original MOs table. It is included here to provide a <br />context for reviewing the INs without having to embed them in the original Goals and <br />MOs table. In the next version of the Strategic Plan, approved Information Needs and <br />their sequence order wiil be incorporated into the MOs table. <br /> <br />Kev to CateQories, as approved bv AMWG Januarv 2003: <br /> <br />CateQorv A: Information Needs that are appropriate for fundine bv power revenues <br />and for accomplishment bv the Grand Canvon Monitorine and Research Center <br />(GCMRC). <br /> <br />AHCIQ memo <br /> <br />Page 3 <br /> <br />[ Fonnatted <br /> <br />[ Forma..... <br />
