NSDSS Web Tool: Environmental Analysis Used to Assess Environmental Impact and Risk Lake Water Budget Analysis Potential impact to lake water supply given uncertain weather Takes into account fish presence and regulatory requirement 95% of models predict this much water will be available 5% of models predict this much water will be available Water Required to build road Because min level for blue line is higher than 55M gal, shows that 50% of models agree that there will be sufficient water, even in dry years. 50% of models predict this much water will be available Because red line crosses 55M gal at 65%, shows that 5% of models predict there will be a 65% chance of insufficient water.
NSDSS Web Tool: Environmental Analysis Used to Assess Environmental Impact and Risk Lake Dissolved Oxygen Analysis Potential impact to lake water quality given uncertain weather Takes into account impact of thickening ice and extraction of waters impact to total liquid lake volume and resulting DO level.
