After looking over all the states and provinces which touch the Great Lakes, we were able to look at which 'cities' saw the most fish and who had the most people looking. (Note that this means places like Philly and NYC were included since they are within a state that borders the Great Lakes).

Here we show the number of observations of fish plotted against the number of observations:

No surprise that the more observations a city had the more fish were observed. the Cleveland-Akron, Ohio area though went above and beyond in their aquatic observing!

And here are the number of people who observed fish vs the total number of people participating:

Again it seems like the Cleveland-Akron, Ohio had greater proportions of fish observers than other cities directly on the Great Lakes (ignoring Philly).

Great Work everyone and thanks for promoting observations of Fish in iNaturalist!
