Upper Beaver Brook Capacity Improvement Project Nears Completion The project is currently on schedule and remains under budget. The project met a substantial completion milestone for the labyrinth weir spillway structure as of early April. Quality control testing and completion of necessary components indicates that the design intent of the structure has been met. On this basis, the District requested that the Dam Safety Branch of the State Engineer’s Office approve the Temporary Fill Plan. Since January, the stored water has increased by about 27 Acre Feet and may fill to the pre-construction high level sometime in May, under current conditions. Tree removal and Flume installation: Due to the likelihood of filling the reservoir above the ‘old’ high water level this season, trees had to be removed along the waterline and a replacement measuring device had to be installed (comprised of a flume with other equipment and located within the primary influent stream). The trees and the old flume would have been inundated with water at the new higher lake levels. These required items were outside the scope of the main construction project and were contracted directly with EZ Forestry and Treatment Technology. The dead and dying trees would have created debris and impacted water quality, so both projects were completed. Outstanding items prior to close out: Replacement of the outlet works gate valve stem, installation of the new staff gauge, grading, safety fencing, site reclamation, monument surveying, and documentation including as-built plans, construction quality control data and final reports. These items are anticipated to be complete around the end of June.

DEDICATION SCHEDULED FOR THE JOHN ROSCOE
RESERVIOR AND DAM AT UPPER BEAVER BROOK
By resolution signed by the Board of Directors on July 9, 2012, the Upper Beaver Brook Reservoir and Dam were
officially renamed to the John Roscoe Reservoir at Upper Beaver Brook and the John Roscoe Dam at Upper Beaver
Brook. Mr. Roscoe’s service and dedication have been invaluable and deserve both thanks and recognition. Accordingly,
the Board of Directors has determined that it is appropriate to rename the District’s primary water supply in his honor.
Mr. Roscoe and his wife, Eugenie, have been residents of Panorama Estates on Lookout Mountain since 1978. Mr. Roscoe
was elected to the Board for every consecutive four year term until 2012. Mr. Roscoe notes that the physical replacement of
the LMWD reservoirs and pipelines is economically challenging due to topography, elevation and distances. His concerns
for the future operation of LMWD, just to name a few, were:
• Eventual replacement of the main transmission pipeline
• Upgrading lateral connections to meet health codes
• Obtaining financing for future upgrades
• Coordination with lateral organizations who wish to upgrade
• Acquisition of firm yield water supplies to offset emergencies and/or future drought periods and offset senior calls
• Anticipation of the State Engineer’s storage increase and runoff criteria
• Anticipation of possible “panic legislation” creating hardships for LMWD
While President of the Board, Mr. Roscoe was instrumental in starting the capacity improvement project by using a labyrinth weir. Congratulations to John from all of us for his many achievements.
REMINDERS
Inactive Taps: Important Dates
The policy has important fast approaching deadlines. If you have not already addressed
your inactive tap status, please refer to the documentation sent last fall (or check out our
website at www.lookoutmountainwaterdistrict.org)
Look for your Annual Drinking Water Quality Report in place of your newsletter next
month!
Construction Locates—Remember the Lookout Mountain Water District ONLY locates
main lines; Lateral’s are responsible for locates on the Lateral and Homeowners' are
responsible for the service line on/to their property (private property). Call 811, but
please understand the limitations and where your responsibility begins.
The Beacon “Eye on Water” technology is still
available. We now have 15 customers utilizing the
Beacon Technology. With summer-time weather
already here, water usage increases for District
Customers. Wouldn’t it be nice to know “How Much
Am I Using”? $1.00 per month and a flat $375 to get
this technology installed on your meter can give you a
warning in real time if there is a leak or high usage. No
surprises on your water bill!
This is a bird’s eye view of
the 10’ Labyrinth Weir that is
now complete at the John
Roscoe Reservoir at Upper
Beaver Brook.
