<br />~ <br />W; <br />~ <br />~( <br /> <br />MONITORING AND EVALUATION ANNUAL REPORT 1993 <br />COLORADO RIVER SALINITY CONTROL PROGRAM <br />LOWER GUNNISON, COLORADO UNIT <br /> <br />""I. <br />?}f.i~ <br /> <br />I. INTRODUCTION <br /> <br />1. Overview and Methodology <br /> <br />Monitoring and Evaluation (M&E) is a~ integral part of all SCS <br />planning activities. The need for M&E in the Colorado River salinity <br />Control (CRSC) Program is mandated and specifically funded. It is ' <br />required that monitoring address hydrosalinity, economics and wildlife <br />effects. PrograE success is measured thru both hydrosalinity M&E <br />(inforEation collected to quantify salt reduction from irrigation <br />system improvements and from irrigation water management) and wildlife <br />M&E (information gathered to Eeasure achievement of voluntary <br />replacement of wildlife habitat). It must also be determined that the <br />salt load reduction is accomplished in a cost effective manner and <br />that sufficient on-farm benefits are received to offset on-farm costs. <br /> <br />Guidelines for M&E activities are found in the Framework Plan for <br />Monitorinq and Evaluatinq the Colorado River Salinitv Control PrOqraE. <br />InCluded therein is an outline which offers a means for consistancy <br />regarding data collection amoung all the CRSC Project Units. <br /> <br />preparation of the Annual Reports is directed by the Monitorinq and ~0~ <br />Evaluation Report Format and Guidelines. <br /> <br />Further detail (for the activities in this Unit) is found irithe <br />Monitorinq and Evaluation Plan for the Lower Gunnison. Colorado Unit <br />of the Colorado River Salinity Control Proqram. <br /> <br />General description of the monitoring and evaluation in' this salinity <br />unit <br /> <br />The Lower Gunnison, Colorado Unit (LGCU) is located in both Delta and <br />Montrose Counties. A portion of the drainage area for the Gunnison <br />River and for the Uncompahgre River (a tributary) are included in this <br />Unit and monitoring activities are distributed herein (Figure 1). <br /> <br />The monitoring and evaluation program was established in August 1989. <br />During the 1993 field season, information was collected from 3 weather <br />stations and from 7 hydrosalinity sites (Figure 2). Data collection <br />from all 3 weather stations and inflow/outflow from all 7 of the <br />hydrosalinity sites was at the desired level. Equipment functioned <br />well overall. <br /> <br />use of existing computer programs was the <br />regards to data; however, a workshop this <br />and then to complete data processing. <br /> <br />greatest challenge in <br />fall lead to problem SOlving <br /> <br />:_,-:':k <br />.><~: <br /> <br />1 <br />
