Honey Lake Valley is a simulation data set for use with the three-dimensional finite difference ground-water flow model MODFLOW by McDonald and Harbaugh (USGS, 1988). The data set represents a four-layer mathematical model of a portion of the Honey Lake Valley, California and Nevada, developed by Mitten and Londquist (USGS, 1991). The modeling was performed as part of a regional hydrogeologic study as reported by Handman et al. (USGS, 1990). The description of the construction of the regional model and its use in characterization of water resources management options, together with the complete model input files provides an excellent opportunity to become familiar with the MODFLOW model and to understand its application to regional-scale water resources studies.

Honey Lake Valley is a 2,200-square-mile, northwest trending, topographically closed basin about 35 miles northwest of Reno, Nevada. Unconsolidated basin-fill deposits on the valley floor and fractured volcanic rocks in the northern and eastern uplands are the principal aquifers. The model represents a 1,700-square-mile area in the eastern part of the valley.

DISTRIBUTION INFORMATION

This data set contains ready-to-use MODFLOW input and output files and includes hard copies of the data set documentation by Mitten and Londquist (1991) and the Water-Resources Investigations Report by Handman et al. (1990). The data set is distributed by IGWMC on a DOS-formatted diskette, requiring 1.1 Mb disk space to down load.
