Main Lake Water Quality and Flooding Analysis

Date: 2016Location: Dakota, CountyClient(s): Minnesota Zoo & The Vermillion River Joint Powers Board

SummaryEOR performed a water quality study for Main Lake on the campus of the Minnesota Zoo. The primary objective of the study was to investigate the watershed and in-lake phosphorus dynamics of the lake and to develop innovative approaches for water quality improvement for the lake.

A secondary component of the study was to evaluate options for addressing high water conditions on the landlocked lake which commonly necessitate pumping to avoid property damage. EOR built a watershed and in-lake model of the system and determined that that 83% of the Main Lake phosphorus load came from internal loading.

EOR developed a suite of in-lake management alternatives to address internal loading and renovation of the lake. Alternatives were also developed to minimize flooding within the lake including routing lake water to a near-by natural infiltration area.

Client Benefits• Determination that primary

source of nutrient loading to Lake was from internal dynamics

• Focus water quality improvement recommendations based on source

• Identified recommendations for alleviating high water levels within Lake

SummaryThe feasible locations, costs, and bene�its of urban LID retro�its were identi�ied using optimized geospatial routines in built-out areas of Edmonton. The goal was to quantify if LID could meet the City’s targets for zero increase in pollutant loading in the future as the urban area continues to grow. Retro�its were evaluated based on sustainable-net present value using Autocase, the City’s Triple Bottom Line criteria, and the expected runoff volume and pollutant reductions. A modeling exercise was conducted using PCSWMM for a neighbourhood draining to a combined sewer system in order to assess the potential reduction in combined sewer over�low (CSO) achieved by LID implementation. Overall, the study identi�ied over 85,000 LID retro�it opportunities which, if implemented broadly across Edmonton, could achieve the City’s water quality targets.

Client Benefits

• A spatial inventory of 85,000 LID retro�it opportunities with estimated costs and bene�its for City staff to reference in relation to redevelopment and other public infrastructure projects.

• Multiple metrics to prioritize broad-scale implementation by cost-bene�it ratios, Triple Bottom Line score, and net present value.
