Founded in 1991 by two individuals passionate about water resources, Martin and Wood is one of the most respected consulting water resource firms in Colorado.


Now in our third decade, Martin and Wood has completed assignments in the Western United States ranging in scope from seven days to seventeen years. Our strength lies in the depth of our experience and the diversity of our skills. We specialize in complicated or controversial water rights issues and have the ability — and persistence — to stay with you for the long haul. 



Joe Tom Wood


Joe Tom Wood, P.E., retired from Martin and Wood in 2018. He continues to apply the knowledge and skills amassed during his satisfying career through technical papers, presentations, and mentoring of other water professionals. Joe Tom specialized in the engineering analyses associated with changes of water rights, plans for augmentation, and water supply/water demand analyses. Throughout his career, Joe Tom has provided the primary engineering for over thirty plans for augmentation in the South Platte, Colorado, Arkansas, and Rio Grande River Basins. In addition, he also worked to protect clients’ water rights by analyzing the effects of changes of water rights and plans for augmentation proposed by others. Joe Tom was qualified as an expert in the Water Courts for Water Division I, II, III and IV, the United States Court of Claims, and the United States 10th District Court.
