Pond Boss Forums GENERAL QUESTIONS Water chemistry Low pH, low Alkalinity in Fresh ponds/Lakes

One helpful option IMO would be contact a couple local concrete contractors to see if they would bring you waste concrete from projects they know about. Contractors are always looking for ways to dispose of waste concrete. Have them dump it in separate piles along your banks. Then when the water is low, arrange the concrete pieces along the shorelines. These will stabilize the shoreline, provide habitat for minnows, invertebrates, crayfish, and probably add some calcium hardness to the water.

It would be helpful to do a soil test of the sediment shoreline. This would give some insight to what native plants would grow along the shoreline to form stability. Examining / identifying the native marginal plants along local water bodies would give you an idea what plants that are likely to grow in your pond's soil conditions. I am not familiar what marginal plants prefer lower pH conditions. Collect some of those plants and transplant them on your shorelines. Be a water gardener.
