Hello – We were pulling up rocks from around my garden pond to replace the liner and came across this big spider, with a baby sac. Do you know what kind it is? If you like the picture, feel free to post it. Just let me know if you do. I named her Mary Beth, the Jurassic Pregnant Pond Spider. We relocated here to a different part of the yard.

Hi Cathy,
This is a female Fishing Spider in the genus Dolomedes, probably the Northern Dolomedes, Dolomedes tenebrosus.  They are generally associated with bodies of water, which makes her habitat around your pond significant.
