Haslam Lake and Lang Creek, located just west of Powell River on the Sunshine Coast, are within a multiple-use community watershed that currently provides drinking water for approximately 20,000 people of Powell River and Brew Bay. The system is also a substantial fisheries resource, with 2003 returns of approximately 1800 Coho, 1800 Chinook, 1000 Pink, 10,000 Chum, 500 Steelhead, and some Sockeye. Water temperatures in this system are very warm during summer and are known to have exceeded 30oC in the marshy headwaters of Lang Creek, though they cool downstream through contributions of cooler tributaries and groundwater, and from evaporation and riparian processes. The British Columbia Ministry of Water, Land and Air Protection (MWLAP) hired Aquatic Informatics Inc. to complete an investigative study on the watershed. The objectives of this study were to: 1. Evaluate recent impacts of warm stream temperatures to salmonids in Lang Creek;2. Estimate the impacts of climate change on Lang Creek salmonid populati
