The Cascade Water Alliance has announced that the refill of Lake Tapps will be delayed until March 15, 2025, due to significant construction activities. This project focuses on replacing a 100-year-old diversion structure to improve water diversion reliability and quality, which is crucial for the reservoir. Working with the U. S. Army Corps of Engineers, the updates will also benefit fish passage at Mud Mountain Dam and enhance sediment flow in the White River.

James Amspacher, the water resources manager, highlighted the significance of the automated gate system, designed to manage water flow while preventing obstructions from logs and sediment. The delay may affect local residents, who rely on lower winter water levels for dock maintenance and the timing of launching boats. The Cascade Water Alliance is optimistic about achieving a reservoir level of 541. 5 feet by April 15, but this is dependent on construction timelines and the water levels in the White River. The lake remains a favored summer spot for the community, prompting recent parking restrictions due to increased crowds.

With the 2009 acquisition of Lake Tapps for municipal water supply, the alliance continues to prioritize both infrastructure improvement and community needs.
