State of Colorado participation in the GASP reregulation project. Page. 2 use outside this state measured at the point of release from storage or at the point of diversion." (CRS 37.81.104) . State line flow is that flow measured at the Compact gage as designated in the Colorado Nebraska Compact. (Article II, paragraphs 1 and 2. Julesburg gage) Lower Section "means that part of the South Platte river in the State of Colorado between the west boundary of Washington County and the intersection of said river with the boundary line common to the signatory states." (Article I, paragraph 4 of the Compact) Compact Account is that flow at the state line that is measured by the Compact gage which is kept by both Colorado and Nebraska officials. Article II paragraphs I and 2 of the "South Platte River Compact". Recoverv Account is that amount of water which the state of Colorado has generated for delivery to the Critical habitat and which Nebraska has the responsibility to deliver to the Critical habitat. By applying simple arithmetic to line I of Example #1 we see that the State line flow is 100 cfs which is the sum of Native Flow + Well Replace + Tamarack Recovery - Junior Diversions (68 + 6.4 + 25.6 - 0 = 100). The Recovery Account reflects 2S.6 cfs which Colorado has generated through the Tamarack Project and has notified Nebraska officials that such water is arriving at the state line. . Everything seems to work well until line 6. Here there is a Junior Diversion of S cfs. The math equation is still the same (93 + 6.4 + 25.6 -S = 120). The problem is that the Compact gage passed 120 and a junior decree somewhere in the "Lower Section" of the river noticed that the Compact was being fulfilled and requested that portion which the Compact says that the junior decrees to the Compact are entitled to divert. Notice that the Recovery account has been reduced by 5 cfs. As the native flows continue to increase so does the diversion by junior decrees and likewise the recovery account reaches zero by line II. Notice that the wells continue to replace until the native flows reach 120 cfs. Line 17 is the first line to show any significant change as the process is reversed and the native flows are declining. As the native flow drops below 120 the wells begin to replace so as not to affect that amount of water available to the junior decrees. By line 23 the juniors have ceased to divert and the problem with the recovery account has corrected itself Notice that the amount of water generated by Tamarack (1624.4 aft) was reduced to 971.6 aft at the state line with a balance 0016.2 aft being diverted somewhere in the "Lower Section" by junior decrees. Example #2 is an illustration of how most thought that the water would be accounted across the state line. All columns are the same as in Example # I. . o V ,r^ 1t-.~vr' \ \' \f~ ~ ~\ ~ V~'~
