{Tidal Potomac Fly Rodders} Re: Thoughts on stream gauge and educate me

Rain often has a very large impact on water temp, and also other parameters as well (turbidity is an obvious one in this region, but it can also affect pH, conductivity, etc.  Actually, in the winter in DC, snowmelt and/or rain/sleet usually jacks the conductivity trememdously because of all the salt applied to the roads.  It's insane how high the cond. gets on some of the small streams due to this.

Went to Lock 10 w. Mauro (fellow TPFRer) yesterday and we found the river to be high and muddy.  He referred me to stream gauge for the Potomac for future reference.

Note the dramatic temperature decrease July 11-12 almost 10 degrees.

Per http://www.nws.noaa.gov/climate/index.php?wfo=lwx
we did get 1.3 inches of rain at National so I figure its the rain. 

Can someone confirm or educate me on correlation?

Thanks.
