Tide pools provide habitat for a wide variety of Puget Sound flora and fauna.  During low tides, the captive inhabitants of tide pools may be closely inspected. 

Great Lakes water availability studies conducted by the U.S. Geological Survey aim to help characterize how much water the Basin has now, how water availability is changing, and how much water it can expect to have in the future.

USGS hydrologist Martha Nielsen examines cuttings as a drill crew works to drill a new monitoring well at USGS station 443647070552303 (ME-OW400A) near Middle Dam on Lower Richardson Lake. The existing well heaved due to frost and had to be replaced.

The island was severed by a breach that may have developed as the back bay drained excess water following the peak of the storm surge, although the breach could have been initiated by waves and surge from the Gulf side. More analyses are required to determine the forcing processes.
