RGDSS Memorandum <br />To: File <br />From: Ray R. Bennett and Andy Moore <br />Subject: RGDSS Surface Water Gaging <br />Date: December 10, 2003 <br />Introduction <br />This memorandum summarizes the results of the RGDSS Surface Water Gaging <br />Program. The objective of this task is as follows: <br />Add additional stream gages along to assist in estimating inflow from the Sangre <br />de Cristo Mountains and river administration. Add new satellite monitoring <br />stations (DCP's) to assist in river administration. <br />BACKGROUND <br />The Division of Water Resources currently operates many stream gage stations in the San <br />Luis Valley. These stations are generally located on the upper and lower reaches of the <br />main rivers, creeks and reservoirs in the valley. These stations are used to administer <br />water rights in the valley and to assure that the requirements of the Rio Grande Compact <br />are met. However the need for additional stream gaging along the Sangre de Cristo's and <br />Conejos River were identified during the RGDSS feasibility study. <br />The Division of Water Resources currently operates areal-time satellite-monitoring <br />program that provides real time data at selected stream gages, diversions and reservoirs. <br />However the need for additional satellite monitoring stations was identified during the <br />RGDSS feasibility study. <br />SURFACE WATER GAUGING STATIONS <br />New stream gage stations were installed at eleven locations along the Sangre de Cristo <br />Mountains to assist in estimating recharge from these areas. In addition two stream gages <br />were constructed on the Conejos River to assist in river administration. The new RGDSS <br />rim stations are presented in Figure 1 and summarized below: <br />C:\Documents and Settings\cI~.DWR\Loca1 Settings\Temporary Internet <br />Files\OLK57\StreamGages_20031210.doc 7/13/20051/4 <br />
