Louisville’s Water Supply System
What You Need to Know
The City of Louisville was founded in 1878. For a number of years the community’s water system was based solely on Louisville Reservoir, which was constructed in the late 1890’s. During the 1950’s drought, the community realized this facility could not handle residents’ needs for water during dryer weather cycles. Therefore, in the mid 1950’s, the City constructed a steel pipeline to divert water from South Boulder Creek at Eldorado Springs to Louisville Reservoir. In addition, the City embarked on a program of acquiring additional water rights to supplement its water supply. As the community grew, additional efforts were taken to enhance the reliability and quantity of water available to Louisville. These efforts included obtaining a contract right to store water in Marshall Lake, a major reservoir in the Louisville area, and constructing Harper Lake Reservoir in 1985. In the 1990’s, after a number of years of significant growth, the City realized the community’s water supply could not be reliably obtained solely from South Boulder Creek and Marshall Lake. Therefore, the City of Louisville joined the Northern Colorado Water Conservancy District (NCWCD), allowing access to Colorado Big Thompson (C-BT) and Windy Gap water resources. Since that time, NCWCD has been the primary focus of the City’s ongoing efforts to provide additional water supplies. As of 2012, the City’s water rights portfolio is valued at over $110 million.
