Vernal pool sizes and types
Vernal pools range in size from the very small to the very large. Some pools would fit in your living room while others might have a surface area over an acre in size. All are relatively shallow and dry periodically (usually annually) or are otherwise free of fish. A typical pool might be 30 feet by 100 feet long and 3 feet in depth. Pools might be found in low areas of a forest, in the floodplain or a river or stream, within a vegetated wetland, in an open field, between coastal dunes, in abandoned quarries or natural rock formations and other areas where water might pool. Some examples of vernal pool locations are illustrated below.
