LIA has many programs and projects aimed at enhancing the water quality of Lake Iroquois, preventing further invasives from entering the lake, reducing and controlling the existing invasive Eurasian Watermilfoil (EWM), preventing sediment from entering the lake, and reducing nutrient levels in the lake which feed the invasive EWM. However, just about everything people do on the land can affect water resources meaning best management practices on the land around the lake is a necessary part of maintaining the health of the lake and the surrounding ecosystem.
- Nutrient enrichment: In particular, accumulation of the nutrient phosphorus in lakes can invasive plants, such Eurasian Watermilfoil, and cause cyanobacteria (blue-green algae) blooms.
- Sedimentation: Soil eroding from shorelines where native vegetation has been removed is carried with runoff from roads and surrounding properties and deposits nutrients, especially phosphorus into the lake. Sediment from erosion also fills in coves and shallow areas, disrupting fish and amphibian habitat.
- Reducing nutrient runoff into lakes through preventing soil erosion, not using fertilizer on lawns or gardens, and proper installation and maintenance of septic systems.
- Preventing soil erosion through maintenance or reestablishment of naturally vegetated lakeshores, lake friendly landscaping, and use of erosion control measures during construction.
- Preventing runoff that can carry sediment and nutrients into the lake from roads, driveways, and lawns by reducing mown lawn areas (mown grass does not soak up runoff), using rain barrels, and replacing impervious surfaces with pervious surfaces wherever possible.
- Maintenance of vegetated buffers using native plants along lakeshores, creating no mow zones near lakeshores, and conserving undeveloped shores wherever possible.
- Insuring that Best Management Practices are followed along the shoreline.
- Joining the Vermont LakeWise program and creating “lake friendly” shorelines.
- Following the provisions of the Vermont Shoreland Protection Act.
