About Coeur d'Alene Lake

Coeur d’Alene is a glacier formed lake whose depth was increased by the construction of the Post Falls Dam in 1906.  The dam is now owned and operated by Avista Utilities for hydroelectric generation, flood control and irrigation.  The water level of the lake is controlled naturally during the summer season, then Avista Utilities drops the level in the fall to create storage capacity for spring snow melt.  The Coeur d’Alene Tribe owns the southern third of the lake.  The EPA has ruled that the Tribe may set its own water-quality standards on its portion of the lake.


Sources for the lake include the St. Joe, St. Maries and the Coeur d’Alene Rivers.  The lake flows outward through the Spokane River where it flows for 25 miles into East Central Washington.

Design Considerations for Coeur d’Alene Lake

Coeur d’Alene and its rivers have a diverse range of bottom conditions/materials, water depths, wave and wake environments, currents, spring debris issues.  We consider each of these factors when developing a purpose driven design for HDB customers.

Design Considerations for Connecting Rivers

St. Joe, St. Maries and Coeur d’Alene Rivers:  These rivers boast mud, sand, and clay banks, featuring strong spring currents and heavy debris flow during spring melt-off. Subject to spring floods reaching up to +7 feet and sustaining year-round currents, the preferred dock for these conditions is the HDB Cedar Log Dock, anchored with long wood or steel pilings. Designing the dock to orient boats facing upstream is the preferred configuration for optimal performance.


Spokane River:  Is characterized by a hard river rock bottom. In this environment, steel pilings are preferred for their superior ability to penetrate the riverbed. The two most popular dock designs for this location are Fixed Pier and Floating Docks. Fixed Pier docks, especially those with bottom-mounted boat hoists, emerge as the top choice for sites with heavy boating traffic, as the fixed dock provides a stable platform unaffected by boat wakes.
