<br />The instream flow right consists of flow in excess of the first development allowance <br />(Carve Out I) and consists of two components: <br /> <br />1) A modifiable portion (Paragraph 4) which may be converted by the Board <br />from instream flow uses to consumptive uses. This modifiable portion <br />provides the means of protecting the second level of development <br />allowance (Carve Out II), which will be available for future consumptive <br />uses, and <br />2) A non-modifable portion (Paragraph 3) which consists of water that must <br />flow out of Colorado because of compact obligations. <br /> <br />Administration <br /> <br />Division Engineer/CWCB tracks running monthly 10 year volumes at the Maybell gage. <br /> <br />Monthly instream flow call triggers are developed for the Maybell gage as follows: <br /> <br />a) determine lowest 10 consecutive year total discharge volume for each month. <br />b) determine monthly development allowance (Carve Out I) and multiply by 10. <br />c) monthly instream flow call trigger = a-b <br /> <br />When the running monthly 10 year volume is less than the monthly instream flow call trigger, <br />junior rights will be called out to meet the instream flow appropriation. <br /> <br />To allow for the use of the second development allowance (Carve Out II), the following process <br />is used: <br /> <br />for large modification of Paragraph 4, recalculate and modify the instream flow appropriation as <br />done originally and recalculate the monthly instream flow call trigger, and <br />for small modifications of Paragraph 4, recalculate the monthly instream flow call trigger only. <br /> <br />c :\miscel\su604 II .a11 <br /> <br />Option II - 2 <br />
