He has spent much of his career providing implementable solutions to water challenges.

Mr. DiNatale has 29 years of experience in the planning, design, construction, and operations and maintenance of raw water supplies. He has managed and consulted on issues related to water quality, watershed protection, reservoir management, water treatment, and wastewater treatment facilities. Mr. DiNatale has been qualified as an expert witness in Colorado Water Court and has provided expert testimony in a number of complex water court proceedings on municipal supply planning and reservoir and drinking water quality. He has provided testimony before the Colorado Water Quality Control Commission on water quality matters and has worked with several nationally recognized limnologists on reservoir water quality issues. Mr. DiNatale served as President of the Colorado Lake and Reservoir Management Association and Regional Director and Committee Chair of the North American Lake Management Society. He has presented at regional, national and international forums on water supply, water rights, water reuse, watershed protection, reservoir water quality and management issues.

Mr. Bliss received his BS degree in Mathematics from Colorado State University and holds a MS in Civil Engineering from the University of Colorado.  He is also a licensed Professional Engineer in the States of Colorado and Texas.

Matt Bliss has worked as an engineer and project manager for several different types of projects, including field data collection programs for the State of Colorado, groundwater modeling and stream depletion computations for the City of Santa Fe, New Mexico and water users in the Rio Grande basin in Colorado, hydrologic modeling and alternatives development for the Northern Integrated Supply Project (NISP) EIS and the Halligan-Seaman Water Supply Projects (HSWSPs) EIS, agricultural needs analyses for the Yampa, White and Green Basin Roundtable, planning and policy tools development for the State of New Mexico in the Lower Rio Grande basin, boat-able days tool development for American Whitewater, Aspinall unit operations analysis and the Bureau of Reclamation’s Colorado River Basin Study consultation for The Nature Conservancy, and augmentation water requirements computation for water users in the San Luis Valley.  Mr. Bliss is not only technically skilled in modeling, but he is also well practiced in using model results as tools and technical support for the needs of projects. His goal is to maximize information from models and technical analyses to ultimately provide the client with valuable information to achieve their goals and objectives.

Arista Hickman, Water Resources Engineer. Ms. Hickman has 6 years of experience in water resources engineering and project management. At DiNatale Water, Ms. Hickman works on RiverWare and advanced Excel modeling of reservoir and water supply system operations, water rights engineering and project management.  Ms. Hickman’s modeling work includes water rights accounting and operations to analyze the impacts of alterative scenarios of coordinated operations for municipal and industrial uses, augmentation, environmental and recreation purposes, river compact compliance, and overall river administration.  Additional models analyze and optimize configurations for surface storage, recharge and well pumping.  Model results not only help determine the size and location of recharge and storage facilities needed, but will also help to identify the maximum water exchange limits and the timing and volumetric requirements for recharge and storage. Ms. Hickman also works on analysis of alternative agriculture transfer methods.

She received her Civil Engineering Master’s degree through the Hydrology, Water Resources, and Environmental Fluid Mechanics program at the University of Colorado. Ms. Hickman worked with the Bureau of Reclamation at the Center for Advanced Decision Support for Water and Environment Systems (CADSWES) and researched changing demands within the Colorado River Basin. She also was a project leader for the University of Colorado’s Engineer’s Without Borders Nepal project and is currently a co-lead on a new project in Nepal with the Rocky Mountain Professionals’ Engineer’s Without Borders chapter.
