Commissioned by the Nulki-Tachick Lakes Stewardship Society (NTLSS) and conducted by EDI Environmental Dynamics Inc., this study evaluates the potential of an aquatic macrophyte harvesting program to improve water quality in Nulki and Tachick Lakes. Among the most hypereutrophic lakes in BC, they face severe algal blooms, low oxygen levels, and fish kills—primarily driven by excess nutrient loading.
​
Key findings include:
-
18% of Nulki Lake and 25% of Tachick Lake are covered by aquatic macrophytes.
-
Harvesting 2.1–3.1 hectares daily could remove 1.6–711.9 kg of phosphorus per day, depending on plant density.
-
Targeted harvesting in the western sections of both lakes, where phosphorus concentrations are highest, is recommended.
-
The program should be integrated into a larger watershed restoration effort, including wetland restoration, riparian buffer improvements, and community education.
​
The study provides guidance on permitting, operational logistics, and long-term monitoring to ensure the success of the macrophyte harvesting initiative as part of a broader lake restoration strategy.
Nulki Lake Weather Station

In May 2024, the Nulki-Tachick Lakes Stewardship Society (NTLSS) partnered with the University of Northern British Columbia (UNBC) to install a weather station at Nulki Lake on the Nielsen family property.
What the Weather Station Monitors:
-
Air & water temperature
-
Wind speed & direction
-
Precipitation & relative humidity
-
Snow depth
-
Soil temperature at multiple depths (via a custom frost probe)
The station is solar-powered and collects data every 15 minutes, helping researchers track lake conditions, climate trends, and ecosystem changes.
Why It Matters:
-
Supports research on water quality and eutrophication
-
Helps identify trends contributing to algal blooms and fish kills
-
Provides data for long-term restoration efforts
-
Contributes to studies on wildfire impacts on lake ecosystems
Fish Research

Fishing & Aquatic Life in the Nulki-Tachick Watershed
Every May long weekend, Saik’uz First Nation hosts an annual fishing derby, celebrating the lake’s rich angling opportunities and bringing the community together.
To support recreational fishing, the BC Ministry of Environment, Lands, and Parks introduced a rainbow trout stocking program in the 1970s in response to population declines. Since 1993, Nulki Lake has been stocked annually with 10,000 rainbow trout yearlings, to promote a sustainable fishery for local anglers.
​
Fish Species in Nulki & Tachick Lakes
The watershed is home to a diverse range of fish species, including:
-
Sportfish: Rainbow trout
-
Native species: Northern pikeminnow, peamouth chub, lake chub, mountain whitefish, redside shiner, longnose sucker, largescale sucker, burbot, and prickly sculpin
There are ongoing opportunities to track and document fish populations, contributing to conservation efforts and the long-term sustainability of the fishery.
