I should add that few fish we have here now in wy are native to the area whre i fish- they where introduced. Many & most of the lakes are manmade with the daming of the rivers etc.
There are 4 dams upstream( going south)from my house which is southwest of casper. The platte is fed from snowpack & mtn streams etc in wy & from the colorados front range mtn ranges south of me also- the rocky mtns & are the rivers orgins. Also south of me is the greatdivide basin area & the red desert of wy- it is a true desert with very little rainfall there-rain dosnt fall to much at my house either

The red desert is surrounded by that great divide line( the rocky mtns) & its mtns- water from one side going& flowing to the pacific ocean & on the other side to the alantic ocean ( and or the gulf?)etc ussally .

It is the only place that froms a circle( a rough circle)of that mtndivide line anywhere that i am aware of - all water stays within that circle of mtns that falls within& forms the red desert- with no outlets to either oceans i believe.


I have seen more rain in the last 2 mths here in the southern us where i am now-then i have seen fall in almost 2 yrs in wy where i live( and its about 7 yrs of drought conditions- even in good yrs of rainfall it isa very dry, semi arid place even in the good yrs of rainfall in my part of wy).
