No. 2 Dam and Spillway Project

This page was last reviewed on July 31, 2026.

The dam and spillway of the No. 2 Lake water supply reservoir has been identified for replacement due to a significant failure classification.

In February 2026, Cumberland Council supported the direction to replace the dam with a rockfill embankment with a central sheet-pile cut-off, including a concrete spillway and low-level outlet on the left abutment. The spillway will include a breast wall to limit outlet capacity to approximately the 1-in-10-year flood, directing more frequent flows toward Cumberland Creek rather than the North Branch of Perseverance Creek.

The project will also include construction of a saddle dam at the outlet to Perseverance Creek North Branch, with a design similar to but smaller than the main dam, including a 1-in-10-year flood spillway; and the upgrade of the Henderson Lake Dam spillway to safely pass increased flows, including the 100-year event with freeboard and the 1,000-year event without freeboard.

Budget and Funding Sources

Senior government funding awarded will help move the project forward without any significant financial burden to the Village:

  • $2.7 million from the Canada Strategic Priorities Fund, which supports infrastructure projects that are beyond the financial capacity of a single local government fund, under the Build Communities Strong Fund (BCSF) Community stream in BC.
  • $4.475 from the Investing in Canada Infrastructure Program

Other significant capital upgrades have been made to the Village’s drinking water system from 2017 to 2021.

Project Phases
  1. Hydrology Assessment
  2. Preliminary Design Phase: The phase includes formal engagement on the preliminary design with partners and stakeholders with interest or possibly impacted by this project before detailed designs are completed.
  3. Detailed Design: Underway in summer 2026 through a competitive tender process.
  4. Regulatory Permitting
  5. Construction: The construction tender is anticipated to be issued in early 2027 for construction in summer 2027.
