The Stream Multi-Cache
simplyred: I will be archiving any caches that need maintenance. I’ve not been caching as much. Moving on to other things. Thanks to all who have enjoyed.

This cache is part of the WTPEHB series. The actual cache is not here, although it's on the same stream. It's around 5 kms away.
The Co-ords above will take you to a place where you'll find the minute portions of the real cache location. Locate the minute portions and add to your GPS. Your best to follow the gravel road till your approx 275m from the actual cache location. Then you'll have to walk in.
SOME STREAM INFO
Dissolved Oxygen:
Dissolved oxygen is the one of the most critical characteristics of our surface waters. Fish, mussels, macroinvertebrates and all other aquatic life utilize the dissolved oxygen to breath, without it not much would survive.
Dissolved Oxygen in streams is affected by 3 primary factors: water temperature, atmospheric pressure, and dissolved solids. Also important is the amount decaying matter in the stream, turbulence at the air-water interface, and the amount of photosynthesis occurring in plants within the stream
Volume and velocity of water flowing in the water body
In fast-moving streams, rushing water is aerated by bubbles as it churns over rocks and falls down hundreds of tiny waterfalls. These streams, if unpolluted, are usually saturated with oxygen. In slow, stagnant waters, oxygen only enters the top layer of water, and deeper water is often low in DO concentration due to decomposition of organic matter by bacteria that live on or near the bottom of the reservoir.
Dams slow water down, and therefore can affect the DO concentration of water downstream. If water is released from the top of the reservoir, it can be warmer because the dam has slowed the water, giving it more time to warm up and lose oxygen. If dams release water from the bottom of a reservoir, this water will be cooler, but may be low in DO due to decomposition of organic matter by bacteria.
Climate/Season
The colder the water, the more oxygen can be dissolved in the water. Therefore, DO concentrations at one location are usually higher in the winter than in the summer.
During dry seasons, water levels decrease and the flow rate of a river slows down. As the water moves slower, it mixes less with the air, and the DO concentration decreases. During rainy seasons, oxygen concentrations tend to be higher because the rain interacts with oxygen in the air as it falls.
More sunlight and warmer temperatures also bring increased activity levels in plant and animal life; depending on what organisms are present, this may increase or decrease the DO concentration.
The type and number of organisms in the water body
During photosynthesis, plants release oxygen into the water. During respiration, plants remove oxygen from the water. Bacteria and fungi use oxygen as they decompose dead organic matter in the stream. The type of organisms present (plant, bacteria, fungi) affect the DO concentration in a water body. If many plants are present, the water can be supersaturated with DO during the day, as photosynthesis occurs. Concentrations of oxygen can decrease significantly during the night, due to respiration. DO concentrations are usually highest in the late afternoon, because photosynthesis has been occurring all day.
