10/6/A-005 Supplemental Data

• Case Number: 10/6/A-005
• Stream Name: Morrison Creek
• Water Division: 6
• Instream Flow App - Doc Type: Supplemental Data

• 0
• A several mile long pipeline is required from the diversion structure to the upper
Little -Morrison Creek drainage. 500 feet of the pipeline would be buried at over 70
feet deep. .
• This concept has the same potential negative impact on the Little Morrison Creek
drainage as the concepts above.
• No cost estimate was developed for this concept.
4. Morrison Creek Canyon Diversion
• A diversion structure would be placed in Morrison Creek Canyon. A pipeline would
transport the water around the hill to Stagecoach. This option may combine both an
open trench pipeline as well as a bored pipeline.
• Access to the diversion would be difficult.
• As this diversion point is below the confluence of Silver Creek and Morrison Creek,
this option would also have the potential sedimentation problem.
• There would be a significant out in the hillside for the road and pipeline.
Commissioner Monger stated that the county would not likely approve this design
due to the environmental impacts.
• The project has been estimated to cost approximately $1,000,000.
5. irrigation Ditch
• This diversion point above the confluence of Silver Creek and Morrison Creek.
Therefore, this option does not get the benefit of the Silver Creek water.
• This diversion site would have excellent access.
• We have considerable concern about the amount of sediment transported in Morrison
Creek from Muddy Creek. This sediment will end up in Stagecoach.
• A several mile long irrigation is required from the diversion structure to the upper
Little Morrison Creek drainage. This potential ditch would impact multiple property
owners.
• Likely very high maintenance costs.
• This concept has the same potential negative impact on the Little Morrison Creek
drainage as the concepts above.
• No cost estimate was developed for this concept.
6. Pump Back from Confluence of Morrison Creek and the Yampa River
•
This diversion point . is below the confluence of Morrison 'Creek and the Yampa River.
• Access may be an issue as the diversion point is on private property (Bill Gay)
• Pipeline would follow the existing road up to Stagecoach.
• Pumps would pump excess water from Morrison Creek up to Stagecoach.
• The ongoing operating cost would be the difference in what we get for producing
electricity and what we pay for electricity as well as the additional electricity losses to
overcome the frictional line losses. t' E f V
• Least environmentally damaging project overalL
• No cost estimate has been established for this concept.
