Ronald Bog is a City of Shoreline Park and is at the "headwaters" of the northbranch of Thornton Creek Watershed. (Cromwell Park is even further "upstream" and August 30th is the dedication of Cromwell Park renovation.) It is the largest watershed in Shoreline and Seattle.  It is home to 5 species of salmonids including chinook. The presence of a Great Blue Heron and other recent sightings of Osprey indicate the presence of fish.

Long ago Ronald Bog was "mined" for peat. This created the "lake like" habitat. 

The Great Blue Heron and turtles utilize a dead tree in the water. Logs and other wood in wetlands and creeks provide valuable habitat and are known technically as "LWD" or Large Woody Debris.

Ronald Bog is a well known bird watching site by Seattle Audubon members
and brings visitors to Shoreline

Many insects are present around Ronald Bog.

Many kinds of ducks frequent the Bog. A Grebe was also
sighted at this outing.

Downstream, the City of Shoreline is beginning work on a project to improve Thornton Creek's flow and prevent flooding.

City is storing large culvert sections until they are installed under 
Corlis Place to provide improved stormwater capacity

Further downstream on King County property next to
the Metro Transfer Station, the creek flows in a section
of natural channel. The City installed "box culverts"
under road crossings that provide much improved fish habitat and 
protect surrounding neighborhoods from flooding.
