Message from the New MADCS President
This is exciting, my first message representing MADCS!!!  
I must first thank Vern Stokes for his hard work and dedication to the MADCS
organization. Vern has helped to grow membership to an all-time high and is always striving to have one of the best educational conferences in the State. Vern will still be very active in MADCS and will continue to serve on the Board.
A little about myself, I am a Civil Engineer by trade and work for Great West
Engineering. I have been involved with water resource projects over the last 15 years working for various water users, private and non-profit organizations, and City/County Municipalities. I am married and have two children. Our family enjoys everything the Montana outdoors has to offer; just about every weekend of the year you can find us doing something in the outdoors whether it's hunting and fishing, skiing or maybe riding our dirt bikes.
MADCS had a very successful 2016 conference in Missoula. We had over 120
attendees and a fantastic group of presenters covering some very insightful topics. Our field trip took us to some great project locations and gave us a glimpse of some of the things happening around Missoula.  Almost 20 vendors were in attendance and I hope everyone had a chance to visit with these folks and maybe pick up some useful information. Please support our vendors when you can as they do a great deal to support our organization.
I would personally like to thank everyone who attended the conference and look forward to another great conference in 2017.

Happy Holidays,
Jeremiah Theys

Who We Are And What We Do

The owners and operators of Montana Dams and Canals face similar concerns:
  • Drought
  • Age related problems
  • Downstream development
  • Recreational users
  • Regulations
  • High costs of rehabilitation
  • Maintenance
  • Liability and Insurance
Aging of infrastructure: The majority of dams and canals in Montana were built between 1900 and 1960. Many components of these dams are at the end of their design life and need rehabilitation. For example, dams built prior to 1970 commonly use corrugated metal pipe as outlet material. Corrugated metal is subject to corrosion, and rarely lasts more than 50 years. Replacement of outlet components is usually very expensive, often costing in excess of 1 Million dollars. It is difficult for many dam owners and operators to fund high cost dam repairs.

Public benefits of dams: Dams have tremendous public benefits in addition to providing irrigation and drinking water. Many reservoirs are used for fishing, boating, and flood control. Montana dam owners are very sensitive to the needs of recreational users and operation their reservoir for multiple uses. However, the dam owners and operators bear much of the cost of operating, maintaining and rehabilitating the dams.

Drought: Prolonged drought in the state of Montana has been especially difficult for Montana dam owners.

Downstream urbanization: Development downstream of dams has a direct impact on dam owners. As the population downstream of a dam increases, the dam owner has to deal with increased liability and stricter regulations. Coordination and communication between dam owners, county planners and developers is critical. Proper planning can help to minimize liability for the dam owner.

Coordination and communication between dam owners: Many dam and canal owners deal with similar issues. Rodent control, reservoir operation, canal lining, inspection techniques and response to emergencies are some of the many concerns facing dam owners. All dam owners have their share of success stories dealing with these issues. This association is a means of sharing information and experiences with one and other.

MADCS was organized to help dam and canal owners with these and other critical issues.
