Arkansas Basin Roundtable Technical Meeting #4 <br />Meeting Summary <br />non-tributary groundwater, M&I reuse, and control of non-native phreatophytes. These <br />families of options were broken down into further detail to comprise the following: <br />^ Active M&I conservation <br />^ Agricultural efficiency <br />^ Permanent agricultural transfer <br />^ Interruptible agricultural transfer <br />^ Rotating agricultural transfer, or fallowing with firming for agricultural use <br />^ Water banks <br />^ New storage <br />^ Enlarge existing storage <br />^ Control of non-native phreatophytes <br />^ M&I reuse by temporary storage <br />The benefits and issues with each of these options were also presented by Kelly. <br />Water Supply Availability <br />The water supply availability at various locations in the Arkansas Basin and the methodology <br />involved was reviewed by Kelly DiNatale. Conditional storage rights by total amounts and by <br />priority were also presented. Various issues are involved that can potentially affect future <br />supply availability. Examples of these factors include interstate compacts and decrees, <br />endangered species issues, instream flows, recreational in channel diversions and changes in <br />climate. <br />Feedback on water supply availability from the BRT members follows. <br />^ Does that mean conditional rights are not economically viable? <br />^ There is no reason for legislators to know numbers for restricted reservoir storage. <br />^ Two Buttes not viable, no yield due to seepage. <br />^ The fact that it is a storage reservoir should make rehabilitation more feasible. <br />- No, because no firm yield on these reservoirs. <br />^ PSOP also conducted a reservoir site study and identified 35 sites - add to dam site inventory. <br />^ Need a slide on groundwater issues: High Plains aquifer, other groundwater availability. <br />^ We should include legal and physical availability of water in discussions. <br />^ New storage - issue add more potential impacts, enlarge reservoir, less environmental <br />impacts. <br />^ Hydrologic variability should be included in factors affecting water availability. <br />Alternatives Development <br />Sue Morea presented the overall approach to the development of alternatives, specifically <br />highlighting the results of the objectives scoring process from previous roundtable meetings. In <br />order to develop alternatives, the performance of the options in terms of the water management <br />objectives were evaluated to give the SWSI team an outline of those ideas that would have wide <br />~~ <br />Arkansas BRT Mtg #4 Summary.doc 11/29/2004 <br />
