The ideal candidate will have fundamental knowledge of scientific data types and collection methods; relational databases including data-structure analysis, database development and design, data-access methods, and query language; programming and scripting languages and utilities; and basic web-design.

The ideal candidate should possess strong verbal and technical writing skills and be able to present technical information in a clear, concise and timely manner; possess knowledge of Colorado River Basin hydrology and reservoir operations; have a basic understanding of Colorado River models, including model inputs and outputs; be able to process large data sets and report results in various forms; and have a basic understanding of statistical hydrology.

GENERAL PURPOSE
Under general supervision, collects, processes and reports a variety of hydrologic, well production and water quality data from various locations throughout Southern Nevada; participates in the deployment, maintenance and repair of field systems to monitor hydrologic conditions and well production; analyzes data and prepares technical memoranda, reports and data submittals; and performs related duties as assigned.

DISTINGUISHING CHARACTERISTICS
Hydrologist I is the entry-level class in the professional Hydrologist class series. Incumbents perform entry level assignments primarily focused on the collection and processing of hydrologic data throughout the Las Vegas Valley, small systems, Lower White River System and Northern Resources Area in accordance with established division policies and Field Operating Procedures. Incumbents perform basic data analyses following approved workflows and documenting methods and assumptions in accordance with detailed Operating Procedures. With experience, work becomes more diversified and difficult and is performed with increasing independence.

Hydrologist I is distinguished from Hydrologist II in that incumbents in the latter class have full responsibility for the design, development, administration and evaluation of hydrologic research programs and projects which require a detailed understanding of complex hydrologic systems.
