Rivers End Neighborhood Association Subdivision (RENA)

Rivers End is an upscale neighborhood located in Eagle, Idaho, ½ mile East of Eagle Road on land formerly part of the Williamson Quarter Horse Farm. The community consists of 114 residential lots, made available in three phases. Phase one and two are complete, Phase 3 homes are complete or in the final completion phase.  The owner of the final lot has not decided to build at this time.  The area has 13 ground water fed ponds that supply water for pressurized irrigation (Apr-Oct) and recreational “catch and release” fishing for residents. Swimming , boating or ice skating is prohibited on the ponds. The ponds are not routinely stocked but do support populations of large mouth bass, sunfish/blue gills and crappie. Approximately 4 miles of paved streets are maintained by Ada County and key areas and major intersections are lighted by a system of 24 street lights. There are two unlighted gazebos in the community. There is a pedestrian bridge and two gravel paths that provide access to the South side greenbelt of the North Channel of the Boise River.There is easy access to shopping in Eagle, State Street to downtown Boise, or endless outdoor activities on the river or nearby foothills.

Past and Present Information

1. In the last year, the Association did extensive research, (phone calls and on-line) into how to remedy the problem. Geese are normally migratory but in moderating climates, such as Boise, they tend to remain in the area throughout the year and their lifetime. When this happens, the natural life cycle is to remain in and return to the immediate area where they were born or hatched. Our habitat, especially along Island Woods Drive and Ponds 6 and 9, includes mildly sloping terrain to access and enter the water. This feature enables the geese to move freely over and around common areas and sidewalks. Other ponds in the sub-division with steeper terrain and more extensive vegetation growth along the banks harbor fewer geese. Our properties provide shelter from hunters and most natural predatory animals. The geese find it easy to roost here overnight after feeding on numerous farm lands around us that have ample food.

2. Chemical treatments have limitations based on environmental issues and silhouetted predator decoys seem to have no effect. Boise Parks and Recreation have started to chemically neutralize the eggs that are laid in spring to help break the “return to where you were born” cycle. This is having some positive effect in the city parks but is not always popular with some residents of Rivers End who want to see the baby geese hatch and develop as a natural process of nature. Another possible option is using simulated firearms noise but the result according to wildlife experts is just temporary and not popular with homeowners in residential areas.

3. One approach that seems to have the most favor and success among the experts is using live “predators” such as dogs to continually harass and scatter the geese until they decide to move on. This approach has promise for our sub-division but how do we pay for such an activity and who and how often would it need to be done to have an effect. Working this is truly a “black hole and money pit.” However if any homeowners are aware of methods that have worked in other areas please let DSI know.


Capitol Lawn and Landscape is continuing to work on the common areas: pruning bushes, overhanging branches on common area sidewalks and cutting the Riparian grasses and vegetation around the ponds. The Board understands some homeowners who have pond overlooks would like some vegetation (cat tails, etc.) to remain, however our contract and the continuing position of the Board is that all areas are treated equally. Consequently this does not allow for special requests by homeowners. Please do not request the landscapers to deviate from this policy.

The pond ecosystems are quite temperamental and conditions vary by season and weather. NC Services treat our ponds with necessary animal and child safe chemicals to keep algae and bottom vegetation to a minimum. Special handling is done on pond 8 & 11 because they are the irrigation source.


Pressurized irrigation in Rivers End is non-potable water that is sourced from ground water ponds located in the subdivision. There is no direct diversion of Boise River water into any of the 13 subdivision ponds. Two interconnected ponds, #8 and #11 which are located along the South edge of Phase one are the source for irrigation. During construction, a large intake pipe system was placed at the bottom of pond #8 and is the direct connection to the water storage vault in the pump house behind the entry water feature.

There are five (5) pumps that draw water from the vault: two to operate the entry waterfall (not part of the irrigation system) and three that operate through a Variable Frequency Drive (VFD) to pump water on demand into the irrigation lines throughout the subdivision. Water leaves the pump station at approximately 60-65 psi but may vary as much as 15 to 20 psi at the homeowner’s connection location as irrigation demand changes throughout the subdivision.

Until the summer of 2015 water entering the distribution system was unfiltered except for the main intake pipe in pond #8 and at each individual homeowner’s filter where water is connected their property. During the 2015 summer an inline filtration system (picture) was added to filter water before it enters the distribution lines. This automated filter detects pressure differentials of 5 psi or more between intake and output lines and automatically back flushes debris into pond # 8 through a relief line. This filter mesh/strainer screen is finer than any used in the small filters installed at our properties. It will catch and then back flush sand and any other solid debris, however it has no effect on bacteria or fungi that are in the water.

Here is the challenge for us this year—the water coming out of the filter is pretty much debris-free but what has accumulated in the distribution lines for the last 10-12 years is problematic. Pressurized irrigation systems don’t have loops in their distribution pipes. They have dead-ends so there can be constant pressure in the lines. Ideally blow-out valves are located at the end of main lines so seasonally or when ever required, a flush out could be done. It appears our system was not installed with these blow-out valves.

Individual homeowner system air blowouts in the fall help some but it’s a hit or miss result. The Rivers End Board is working with our landscape contractor to determine if we can install some blow-out valves in our system. If not, eventually the system will cleanse itself but the timeline for that is inconclusive.

Clean your main filters and any micro-filters in drip lines regularly. If you notice a pop-up not spraying properly, take off the nozzle and clean the plastic screen. Homeowners can also flush their individual distribution lines (zones on the clock) by manually turning on a zone and removing the sprinkler head or nozzle nearest the end of the line. Let the water run freely and then replace the head or nozzle.

Hopefully with a little knowledge and some basic home maintenance our systems will perform to the satisfaction of all.


Please be a courteous pet owner and “Scoop the Poop”.


The web site below has considerable information regarding Ada Counties response to mosquito abatement. Essentially you can ask for up to three options: a larva spray, and adult spray, and if its really bad – an aerial spray. Homeowners say we pay for this service in our taxes! For more information:
