My well has been decreasing in productivity over the last week or so here in the mountains of CO. It fills a 400 gallon cistern in the basement that is no longer staying full as it usually does. I went outside to take a look at the well today and think I found the problem, but wanted to consult with you all first. The pump/well company came out about a year ago to service the pump and ended up putting the pump down another 5-10ft (from what I remember) farther than it was before. As a result, my well cover no longer really covers my well. As a result of the high winds and low temps we've had here lately, the well is now filled with snow (at least at the top). I am guessing this is freezing the outside of the pipes, reducing the flow into the cistern/house. I was going to use a blow dryer to melt the snow or just pour warm water over it to get rid of the snow, but wanted some advice before I did anything stupid/caused any more problems. I have attached some pictures to give you an idea of what is going on. Thank you in advanced for the help friends!!!
