Project to Increase Storage Capacity at Upper Beaver Brook Reservoir Completed

As of January 1st, 2018, the project was officially closed out by the LMWD and the CWCB (Colorado Water Conservation Board).  The new spillway is being monitored under the First Fill Plan, which will last for a minimum of one year.  Notice of Completion CWCB-UBB

Project Timeline Summary

Design:   August 2013 to April 2016

Construction funding secured:  November 2015

Construction:  June 2016 to June 2017

Project Completion and Approval:  June 2017 to December 2017

Location

John Roscoe Reservoir at Upper Beaver Brook located on Lookout Mountain Water District lands, accessible through easement on USFS lands. Approximately 7.5 miles northwest of Evergreen, Colorado, in Clear Creek County within the Beaver Brook Watershed. The only adjacent property is under the jurisdiction of the United States Department of Agriculture.

Project Summary

The John Roscoe Reservoir at Upper Beaver Brook is the primary source of water supply for the Lookout Mountain Water District, which serves approximately 485 homes, several private businesses, a high school, and a number of government-owned facilities.  The reservoir was built by the City of Golden in 1924, improved by the LMWD in 1990 (holding 257 acre feet of water when full — each acre foot of water contains 325,851 gallons). The District supplies its customers with a total of 140 to 180 acre feet of water in most years, so 257 acre feet provided little carry-over storage capacity to provide for a multi-year drought.  Water supply is entirely dependent on the annual stream flows from the Beaver Brook Watershed and related water rights.

The design safety margins were such that the existing upper dam and reservoir is physically capable of storing an additional 138 acre feet of water if the reservoir’s water level is increased by 10 feet. Engineering studies indicated that a 10-foot concrete labyrinth weir could be installed to safely raise the dam’s spillway and this project was completed in 2017.  With this expansion of the reservoir, its new capacity is now nearly 400 acre feet. Water rights are not expected to be able to fill the reservoir to 100% capacity in every water year.

Budget

Total costs for the project were estimated at about $3,325,000 including engineering, legal, water rights, permitting, financial planning, and construction from 2013 – 2017 (excluding financing).  State and Federal permitting requirements have been a significant part of the initial costs (LMWD received a matching grant for the engineering and permitting phase). The CWCB issued a loan for the construction cost of $3,099,690 but only $2,746,062 was expended, a savings of about $353,625.

See below for the public announcements.  The District’s distribution water main originally had a proximity conflict with this project, but the District’s engineer worked with CDOT to successfully resolve it so that it would not impact the District’s customers or create water outages.

Lower Beaver Brook Dam

Comments Off on Lower Beaver Brook Dam

Unusually sustained precipitation coupled with normal spring snowmelt in the Beaver Brook Watershed has resulted in higher than normal flows in Beaver Brook.   The State Engineer’s Dam Safety Branch requires monitoring under certain conditions, including extreme weather events, higher than normal flows through the Lower Beaver Brook dam spillway and a higher than normal pool level.  Under the Dam’s existing Emergency Action Plan, the Lower Beaver Brook Dam is currently being monitored at a Level 1.  This is a precautionary Level and does not indicate deteriorating conditions to the dam itself.  The dam’s crest is not designed to “overflow” or “overtop” and overtopping should be avoided.  If the spillway cannot adequately pass an unexpectedly large flow, the dam crest could be “overtopped.”  The District is doing everything possible to maintain dam safety under the Emergency Action Plan and is in compliance with the State Engineer’s direction.

The District had a window of time between the first heavy rains on Tuesday and the expected precipitation later in the week in which sand bags were placed to increase the freeboard (freeboard is the distance between the pool level and the dam crest).  Having more freeboard creates a greater margin in order to avoid an overtopping.  The sand bags do not alter the amount of water that can be stored on a permanent basis, nor control the water entering or leaving the spillway.  The extra barrier provides a safety buffer, and would serve to channel water in the pool toward the spillway at approximately the same rate as the inflowing beaver brook water, should the water pool reach the original dam crest elevation.

Recent events have caused concern to residents in Beaver Brook Canyon, especially those who experienced flood damage in September of 2013.  In 2013, types of damage included culverts that were overwhelmed, severe damage to bridges, damage to structures, and severe damage to public and private roads and driveways; utilities were also damaged and access to property was restricted.  The District had over $100,000 in property damage and many thousands of dollars of other types of mitigation costs.  During the extreme weather events in 2013, the Lower Beaver Brook Dam was also monitored at a Level 1.  The County as a whole was included in the federally declared disaster areas in Colorado and FEMA became part of our everyday conversation.

We have chosen to be located in a natural “funnel” at the bottom of a 5,120 acre drainage basin, known as Beaver Brook Watershed.  We often find ourselves worried about water shortages, but this time it is the opposite.  Fortunately, this time around residents are more informed and aware, and some property has been improved during or after the 2013 flood mitigation occurred, and can now withstand greater flows within Beaver Brook.
