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.

Boise River Annexation and Rezone - City of Eagle UPDATE

The city of Eagle is requesting an annexation and rezone from RUT (Rural Urban Transition – ADA County designation) to PS (Public/Semipublic). Upon incorporation into the Eagle City limits hunting via the discharge of a firearm on the identified property will be prohibited. The 40.5 acre site is located along the north side of the north channel of the nBoise River approximately 1/4 mile east of Eagle Road. UPDATE: Oct 5 2016 Hearing will be: Oct 25, 2016 at 6:30pm, Eagle City Hall,660 E Civic Lane, Eagle, ID


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 Sentry Management 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.


The irrigation system sources water from Pond 8 (behind the entry water feature).  There is a flow between Pond 11 and Pond 8 but no other ponds.  The ponds are strictly ground water fed with no diversion water from the Boise River.

There are five (5) pumps in the vault.  Three (3) pumps for the irrigation system and two (2) to provide water for the entry water feature which are not connected to the irrigation system.

Irrigation pump one (1) is a small jockey pump that keeps a minimal pressure in the system when the demand is basically static (no down line demand for water).

Irrigation pump two (2) is a twenty five HP pump that is set to provide 80 PSI water to the system.  It is controlled by a VFD (variable frequency drive) that sends a signal to irrigation pump three (3) when demand on the system exceeds the output of pump 2.

Irrigation pump three (3) is a duplicate of pump two and when activated by the VFD (about a five (5) PSI differential) comes on to keep the system pressure in that 80-85 PSI range.

Pressurized water is routed from the pumps to the system filter (installed about 3 years ago).  The  filter is self cleaning and runs its cleaning cycle anytime there is a 5 PSI differential between the water coming in and going out to the down line system.  Down line system pressure will probably drop a few PSI during the filter flush operation.  Based on the cleanliness of the water coming into the vault this flush operation will happen numerous times a day.  The filter screen in this system filter is smaller than most filters that are installed when the water enters the homeowner’s property.  This should filter out most particles but does not keep biological growth from occurring in the down line systems.

Routine homeowner maintenance of their irrigation components is a must to keep the system operating efficiently.  This means routine cleaning of the main filter, drip line filters (if installed these have finer mesh than your main filter) and  individual filters that are part of the sprinkler head itself.

If you observed the inadequate pressure to run your system, try the following:

Check and clean all filters.  Remember if they are catching debris or biological growth they are doing their job.

Make sure you are only running one zone of your system at a time.

Adjust the time of the day you water.  When the common areas are being watered there is a maximum demand on the system.  Popular watering times seems to be between 4:00AM and 8:AM.  This is another time of maximum demand on the system so changing from this time might help.

Remember there are 114 homeowners properties and all the common areas in our system requiring irrigation so staggered watering by homeowners has a positive effect Coordination between the Association and the Landscaper is also necessary to minimize excessive demand on the system.

One final note: Be sure to have your sprinkler system blown out in the fall once the irrigation is turned off or you elect to isolate your system from the subdivision system.  If you don’t there could be component damage from freezing or residue/algae that gets trapped in your system.


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:
