What’s Happening in NWA Circa 1950

• 1950 – Sam Walton purchased a store in Bentonville and opened Walton’s 5 & 10

• 1952 – Don Tyson Graduates From the University of Arkansas

• Late 1950’s – Meatpackers begin to base operations in NWA

• 1958 – Tyson’s Randall Road Plant Opens• Joe Steele looking to expand his canning company

What’s Holding Us Back?

• “By the 1950s, the springs that had always watered the area could not produce enough water to supply the area’s growth” Quote about Springdale from the Encyclopedia of Arkansas History & Culture

NWA Water Sources

Water Supply Sources

◦ Fayetteville: West Fork/Clear Creek/Lake Fayetteville/Lake Sequoyah

◦ Springdale: Spring Creek Springs/Shiloh Springs/Fulbright Springs/Little Osage Creek

◦ Rogers: Frisco Spring/Diamond Spring/Deep well/Lake Atalanta

◦ Bentonville: Unnamed spring/Ford Spring

What are we going to do DAM IT!• 1927: Flooding results in

almost 100 deaths and 1 million in damages

• 1929: COE begins study of White River basin

• 1938: FDR signs Flood Control Act

• Flood Control Act authorized civil engineering projects such as dams, levees, dikes, and other flood control measures through the United States Army Corps of Engineers

Page 8: Past, Present and Future Water Supply Planning and Needs Present and Future Water... · Past, Present and Future Water Supply Planning and Needs By Bill HagenBurger, P.E. Plant Engineer

The Birth of Beaver Lake

• 1940’s a group of NWA businessman push for the construction of a dam near Eureka Springs

• Beaver Dam Association Formed after WWII

• 1954: Congress adds Beaver Reservoir to the Flood Control Act for the purpose of:

– Flood Control

– Power Generation

Page 9: Past, Present and Future Water Supply Planning and Needs Present and Future Water... · Past, Present and Future Water Supply Planning and Needs By Bill HagenBurger, P.E. Plant Engineer

Ok we are all set BUT HOLD ON!

• COE performs Cost Benefit analysis based on– Flood Control– Power generation

• Cost GREATER Than Benefits• 1958 Congress passes the Water Supply Act • Water Supply Act allows COE to include Municipal

Water Supply in Cost Benefit analysis• Benefits GREATER Than Cost• CAVEAT

Page 10: Past, Present and Future Water Supply Planning and Needs Present and Future Water... · Past, Present and Future Water Supply Planning and Needs By Bill HagenBurger, P.E. Plant Engineer

The Birth of Beaver Water District• Federal Water Supply Act requires a local sponsor to

pay for the water supply portion of the lake• Arkansas Legislature passes Act 114 of 1957

– Creating Regional Water Distribution Districts

• August 27, 1959 Beaver Water District is Born!– Includes Benton & Washington Counties– Sells water to cities of Fayetteville, Springdale, Rogers &

Bentonville– Governed by a Six member publicly elected Board of

Directors

Beaver Water District’s Future

• Western Corridor pipeline project• Construction for additional Emergency Power• Continue to be proactive about drinking water

regulations• Be involved with local and national drinking

water associations

• Continue with our Watershed Protection Program

Page 22: Past, Present and Future Water Supply Planning and Needs Present and Future Water... · Past, Present and Future Water Supply Planning and Needs By Bill HagenBurger, P.E. Plant Engineer

Regional Growth Study

• Completed in January 2006

• Develop population forecasts and water demand projections through 2055

• Investigate the need for a new transmission line to serve existing & future customers

Key Findings

• Growth will create water demands that will exceed BWD’s deliverable capacity

• Development Could “Box-in” BWD

• Rapid growth (residential congestion)

• Future water demands will occur West of current service area

• Increasing easement costs

Page 26: Past, Present and Future Water Supply Planning and Needs Present and Future Water... · Past, Present and Future Water Supply Planning and Needs By Bill HagenBurger, P.E. Plant Engineer

Western Corridor Pipeline Project• Currently obtaining easements

for two future 60” dia. pipelines

• Cross I-49 then parallel future 412 Bypass to east of Hwy. 112

• Construct Pump Station near Willis Shaw Elementary School

• Customer Cities Future Pipelines will go the new PS

Closing Thoughts

• Beaver Lake is needed to meet the future drinking water demands of the region

• Beaver Lake has been a tremendous investment for the region

• Beaver Lake is a very important asset for the region and it needs to be treated as such
