9- 'I:." ~ ....0:">\ .. ~. :. .) .~ ~ .' J .-- b. Mt. Vernon Creek flows arudded to the flows at the Morrison Gage adjusted by Item lL For Morrison Gage virgin flows oC less than 30 ds, the Mt. Vernon Creek flows are zero. Above 30 ds, the Mt. Vernon aeek flows are assumed to be equal to 2 percent oC the Morrison Gage virgin flows. I I I I I I I I I I I I I I I I I I I 2. Return flows !rom diversions upstream oC the Bear Creek Lake and downstream oC the Morrison Gage are assumed to be equal to zero. This assumption is reasonable since the Harriman Ditch is now lined or in a pipeline, and there is very little irrigation above Bear . Creek Lake. It was agreed amongst the engineers that Turkey Creek inflows would be ~nsidered zero, which is consistent with the assumptions for the Model. The Town oC Morrison diverts upstream oCthe Morrison Gage, but Cor this study it is assumed that it diverts below the gage. Some return flows occur upstream oC Bear Creek Lake as sewage effluent d~~h"rged !rom Morrison's wastewater plant, whid1 has been neglected in the Model. 3. Depletions !rom exempt wells upstream oC the Morrison Gage are assumed to be zero. 4. Recharge !rom Bear Creek Lake to the Arapahoe or Uramie.Fox HiIJs aquifers are assumed to be zero. A rise in some of the downstream Arapahoe wells after the permanent pool in Bear Creek Lake was filled was observed. However, the USGS is no longer monitoring these wells so that no official evidence of any further rise has been documented. 5. All transfers of water rights in Bear Creelc to new points of diversion and new uses are strictly adminiqered aa:ording to the decrees granted in Water Court. All oC these water rights, as well as other rights will be diverting the full amount granted by these decrees at all times when in priority. 6. The State of Colorado's Simonton Ditch for 2.2S cis is assumed to be in priority whenever water is available at the Morrison Gage. This assumption allows greater diversions by the State's Simonton Ditch than those shown on page 2, which may result in artificial shortages to other Bear Creelc Water rigbts, espec:ialIy during dry periods. However, the difference in the 2.2S cis and that shown on page 2 does allow for a poss.Ible S"ct'....~ transfer of a small portion of Denver's Simonton Ditch ownership. 7. Return flows will provide sufficient water to meet the McBroom Ditch demands at all times. 4
