Drain the alpine lake IPPs – Replay

An item first published in August 2011, repeated because it demonstrates that small hydro power projects are not benign.


A regular reader informs me (and people in the msm) about issues surrounding IPP’s. In a message today, he says many things worth repeating and this is only one:

“The run of river IPP’s are not run of river. Many of them are drain the alpine lake IPP’s. Tyson Lake is a prime example.

Sunshine Coast IPP shut down over fisheries fears, Scott Simpson, Vancouver Sun, May 2010:

…The proponents are seeking relief from federal water pollution laws, as applied under the Fisheries Act, while stream-keeper groups suggest a resumption of power generation at Tyson Creek generating facility will harm fish populations downstream in the Tzoonie River.

The Tzoonie is located at the head of Narrows Inlet east of Sechelt peninsula, and supports both spawning and rearing populations of salmon and migratory trout.

…The facility’s problems first came to light in mid-January [2010], shortly after it was commissioned and for the first time began shipping electricity to BC Hydro.

The facility was designed to draw water from the bottom of Tyson Lake, a small, barren alpine lake at 3,000 foot elevation, and pipe it downhill to a generating station in Tyson Creek. The creek flows into Tzoonie River, which is used by salmon.

Within a few weeks of beginning operations, the facility began releasing cloudy water into Tyson Creek — suggesting that a disturbance had taken place under the ice-covered surface of Tyson Lake and caused a large release of silt into the lake. It appears that drawing down the lake for power generation caused the surface ice to scour a delta situated at one end of the lake.

The cloudy, or turbid, water was observed in the Tzoonie River and all the way out to the river’s estuary in Narrows Inlet…

  1. That is of no surprise. Campbell/Clark and the BC Liberals, have never cared about BC. They were just out to strip this province, for every cent they could thieve. They don't even give a damn, about their people. We are just to steal from.

    Do they care about, the dirty diseased fish farms, killing our salmon? What do they care, the First Nations people depend on the salmon. Do they give a rip, if the bears, eagles and other wildlife depend on the salmon? Do they care about, the dirty Enbridge pipeline, crossing thousands of, rivers, streams and over lands? Do they care if, the dirty oil tankers from, China, the U.S. and Europe, come into our coastal waters. Do they give a damn about oil spills? They are even so stupid. Harper and Campbell have worked to drill oil and gas, off BC's coast. There was a 6.1 earthquake in the Queen Charlotte's. That's exactly how disgustingly stupid they are. What about dumping toxic mine waste into lakes. No they don't care about that either. Greed comes first.

    I am so sick of this evil, dirty, corrupt BC Liberal party. Their lies, deceit, corruption, thieving, their crimes. Their corrupt courts, corrupt judges, special, corrupt prosecutors, corrupt police, corrupt BC Elections, and the useless g.d. media, in this province.

    Is there a BC Liberal, that doesn't belong in prison? I think, Campbell and Harper, would be excellent cell mates.
