Man-Made Lake Features

Lake Opuha isn't just a stunning swimming destination; it also features impressive man-made structures that enhance its utility and environmental management. At the heart of this is a 50-meter high earth dam, which boasts a crest length of around 300 meters.

This zoned earth and rockfill dam, with its clay core rockfill design, showcases advanced dam engineering principles. It's built on rock and contains approximately 800,000 cubic meters of fill, ensuring stability and durability.

The hydroelectric power generation system operates with a single horizontal Francis turbine, providing a continuous capacity of 7 MW. Water flows from the bottom of the lake through a 200-meter horizontal penstock, driving the generator efficiently.

This system not only supports energy generation but also plays a crucial role in water management. With a radial gate at the downstream weir, water is released to maintain ecological balance in the rivers below.

Priority is given to environmental releases and community water supply, demonstrating a commitment to sustainable practices. However, challenges like invasive algae and sediment discharge highlight ongoing efforts needed to protect river health.

Recreational Activities Available

At Lake Opuha, you'll find plenty of recreational activities to enjoy.

Whether you're casting a line for trout, gliding across the water in a kayak, or wandering along scenic walking tracks, there's something for everyone.

This spot truly caters to all kinds of outdoor enthusiasts.

Fishing Opportunities Abound

Fishing opportunities abound at Lake Opuha, offering a diverse range of species and experiences for anglers. You'll find rainbow and brown trout thriving in the lake, with rainbow trout present since before the dam was built and brown trout introduced later.

Additionally, there are Chinook salmon, although they're landlocked and have a shorter life expectancy. The fishing season for trout runs from October 1 to April 30, while salmon fishing is permitted until March 31. Be sure to follow the fishing regulations, which include a bag limit of six fish in total—four trout or six salmon—and a minimum size limit of 300 mm for salmon.

You can enjoy various fishing methods, such as trolling from a boat or spinning from the shore. Multiple boat ramps make launching easy, and on sunny days, sight fishing for cruising browns can be particularly rewarding.

With ideal water levels and a low to moderate number of anglers, you can expect a pleasant experience. Don't miss the annual fishing competition in November, which is a great way to connect with fellow fishing enthusiasts while testing your skills!

Local Wildlife and Environment

Lake Opuha brims with diverse wildlife and unique ecosystems, showcasing a mix of indigenous and introduced species. As you explore the waters, you'll encounter fascinating indigenous species like the longfin eel and kōura, both vital to the local ecology. The lake is home to both longfin and shortfin eels, along with Stokell's smelt, whose declining populations are concerning for ecological health.

Introduced fish, such as rainbow and brown trout, provide exciting fishing opportunities, but they also pose challenges for native species. The trout and salmon fishing seasons, running from October to April, draw anglers eager to catch these prized fish. However, keep an eye out for bag limits to help maintain balance in the ecosystem.

Monitoring efforts, including eDNA sampling, provide insights into the lake's ecological health, revealing ratings from "average" to "pristine" across various tributaries. While the South Opuha River boasts a pristine rating, concerns about high-nitrate tributaries downstream remind us of the delicate balance in this environment.
