I live fairly close to a private lake, which has been experiencing growing problems with algae blooms and flooding. The community association hired contractors to dredge and deepen the lake. Turns out they vastly underestimated the amount of work necessary and the amount of space they would need for dumping. Which leads us to ...
The lake as it stands.
After being drained bone-dry, the lakebed developed small fissures - canyon territory in miniature. Then it started to grow over. There was still low water, creating a marsh-like environment. The growth continued, now a wild underbrush filled with poison ivy. And as the dredging stopped from lack of funds - got to love contractors who won't finish what they started - great mounds of dirt have been left behind.
This has completely changed the local ecosystems. The explosion of turtles and bullfrogs subsided into a growing flock of herons and an osprey or two. The herons have become so comfortable they're squabbling for territory. The ducks have more or less vacated the premises for other local ponds. Worse, a lot of the fish are dead, and the buzzards are definitely enjoying themselves.
To date, the project has basically been abandoned for about a month. Now they seem to be doing something, but I don't know if it's fixing something or pumping the water back in and hoping for the best.
Sure glad I don't live ON the lake.
