There are pros and cons of Beaver Dams.

Do they block spawn movement? "no they are natural and usually last less than 5-10 years"

Does you Trout Of A Lifetime live here? "yes for stream wise trout the biggest ones are in spring fed beaver dams"

Do long term dams make water temps go up and ruin the ph? "not often as far as i have seen"

Do you get fired up when you see a dam? "always"

Have you ever had 2 outings at a beaver dam where both times you scored over 100 trout? yes and they were bigger and badder than anything else i had ever caught in that brook"
What do you think of them?
