| 520 | |a"The Lake Chubsucker population in the East cell of the St. Clair Unit is estimated to be below the minimum viable population size of 600–1,000 adults (East cell estimate of 234–247 adults and 1,302–1,375 total individuals), with the probability of extinction greater than Pr = 0.12 in the absence of water level drawdown. Drawdown of the East cell will increase the likelihood of harm to the population, with greatest initial increases in the probability of extinction beginning at drawdown increments of 0.2 to 0.45 m below NOL 176.1, and the probability of extinction reaching 1.0 at drawdown increments of 0.45–0.75 m below NOL 176.1"--Conclusions, page 24. |
