Harvey Lake Found--ha ha


It's part of the Duteau system...actually. 
Yup.
Not some newly-discovered water source near Grizzly Swamp.
Not some indistinct Gold Paradise water bog.

Who knew?
Obviously not me.

Here's details, this from Technical Memorandum 3:

"The outlet at Haddo supplies the controlled releases to Lower Duteau Creek  ... further downstream at Harvey Lake."

"Harvey Lake is the headpond created on Lower Duteau Creek for the main pipeline diversion into the GVW distribution system.  The head pond and associated infrastructure were completed in the late 1960s..."...travelling intake screens, gas chlorination system, flow meter and telemetry.  AECOM (2006) identified Harvey Lake potential upgrades to the headgates as part of the Duteau WTP upgrades."

"Prior to construction of the Duteau WTP, GVW commissioned Earthtech (2005) to examine options...updating the Harvey Lake intake.  The intake pond requires dredging every five to ten years...frequently cleaning silt and debris from the infrastructure.  The study examined different forms...prevention and complete bypass.  The study summarized that the most economical option was to replace the infrastructure one day."

See this document:  Headgates Dam Improvements (Ref #372-14-14.03)  regarding sediment removal and the protection of incubating Coho Salmon eggs. 

Harvey Lake found...it's basically Duteau "headgates"

"Sheesh...", exclaims Kia.

The plot thickens now with three water sources...yup, three (technically).
A whole new Vernon irrigation system is born?

At the expense of domestic customers...who will be paying for the entire system...always.
