Stormwater Inspection Checklist - Clarity/Support Needed

Hello Michael, There are about eight ponds that all feed into each other (like the Great Lakes between Canada and U.S. and the St. Lawrence Seaway). The water does not actually drain off of the site, they keep their levels even based on how much/little rainfall we receive. If there is not enough, the irrigation is turned on manually. If there is too much, we hope there isn't an overflow (we have an on-site person that watches it). The ponds evaporate 1-2"/day depending on the weather. In the rainy season, the rainwater from the roofs (4 buildings) filters through stones and grassy sections and flows into the ponds, therfore, no need to turn the irrigation lines on to raise the pond levels. Unfortunately, the rainwater comes when we don't really need it (wet season). The ponds all have a drainage system and the plastic filters between the ponds are cleaned as needed (bi-annually). Maybe these ponds are irrelevant because the water never actually leaves the site to go to the stormwater drains off-site? Basically, all of the rainwater stays on site, and we add water for irrigation and raising the pond levels. I do not have a "plan" that shows or proves this, just an older Landscaper that explained how it works. No way to prove this. The ponds all have cement bottoms that are sealed aside from the drianage pipes between them. Anyway, I am either way on or way off track here. I think it is a good concept though! Your thoughts? Thanks, Michelle
