Hi all,
My first post and I'm still reading and absorbing the wonerful info I've found here ...
First, let me describe my location ...
My 5ac parcel sets on a steep ridge. About 3 ac is "usable", and then a steep slope (aka >60% steep

) drops to the other 2ac. My drive way, house and shop are on the "upper" side. My driveway runs down the upper side of the "ridge" and has a 6" PVC culvert that feeds a "mud pit" with seasonal runoff (runoff from neighboring property, gravel road). it actually collects quite a bit of the watershed, but is still seasonal (in the PNW, it rains LOTS during the winter, but is quite dry during the summer).
The "mud pit" (aka future pond site) is about 25' by 50' long. It the input, it's about 1' below the drain, and then narrows to about 4' across and 4' below the drain. Very little to just "fill" the ravine at the end ... (I'll get some pics up very soon, since it's hard to describe).
I'm thinking I could hoe out around 1-2' of muck,
put some fill where the exit narrows, and have a nice 25'x50' pond. With my soil (very sandy), and the smallish size, I'd probably need to put down a liner (and perhaps put 2-4" of "sandy" fill over the liner?)
Being a newb tho I don't want this to become a 25x50 sesspool, or could easily build a "damn" that would just fail in a few years.
Would really appreciate some opinions about the "task" ... I could just make this be a serias of "stream fed pools" (perhaps with recirculating pump for the dry seasons ...
(pics will be in a followup post here in an hour or so ...)
