The current surface area of Chapman Lake is given as 345,518 m2 at lake full. At 8 meter drawdown, the area is reduced to be 194,445 m2. That is 56% of lake full surface area. The northeast stream is classified as high quality fish habitat suitable for all stages of fish life cycles (spawning, rearing, overwintering, migration, and spawning/holding). It contains 240 meters of good habitat that is critical in sustaining fish. During drawdown the northeast stream would flow onto dry lake bed leaving fish exposed without a channel, cover or streamside vegetation. The drying mud flats would extend 137 meters from the outflow to the lake at 8 meter drawdown. It is unlikely any fish would survive the transit and access to Dolly Varden spawning areas would not be possible.
