Drained & Refilled: The Erickson Garden Pond

Over the past decades, the Erickson Garden pond has gradually become shallower as silt and organic material accumulated. One adverse effect of the shallower water was a relative increase in temperature, making it less hospitable as a frog habitat. A full restoration of the pond will come eventually, but in the meantime, remediation was called for. Neill Cumberbirch, member of AEF's House & Garden Committee, reports: "It took five days of digging and wheelbarrowing of material from the pond to the bins located outside the gate on the boulevard. There was 3 to 4 inches of fine silt on top of 8 inches of matted root material, leaves and astonishingly well preserved pine needles and below that the original membrane. We removed material down to the membrane being careful not to damage it. The total water depth is now at its original 18”. Before we started it was 6” ... We left approximately 20% of the original root mass in the pond for regeneration of the waterlilies and irises."
