Coeur d’Alene Lake Water Budget Development

Conducted in cooperation with Idaho Department of Water Resources

Methods

The main study area is the lake boundary, with water-use data focusing on the city of Coeur d’Alene and smaller incorporated towns around the perimeter of the lake.

We will develop datasets from existing (monthly and annual data collected between 2000-2005) and newly collected data in both tabular and geospatial (GIS) formats with appropriate metadata. All site-specific data for water use will be stored in the Site-specific Water Use Database System (SWUDS). Datasets will be available to access and manipulate using existing technology and software, and they will include:

Data
Collection or Computation Method
Inflow, outflow, changes in storage Existing streamflow USGS gages
Precipitation National Weather Service
Evaporation estimates Previous studies and other published methods
Publicly-owned supply well withdrawls Purveyor measurements
Domestic, commercial, and industrial withdrawl estimates Standard methods
